```
bazel [&lt;startup options&gt;] &lt;command&gt; [&lt;args&gt;]
```

or

```
bazel [&lt;startup options&gt;] &lt;command&gt; [&lt;args&gt;] -- [&lt;target patterns&gt;]
```

See the [User's Guide](/versions/9.0.0/docs/build#specifying-build-targets) for the
target patterns syntax.

## Option Syntax

Options can be passed to Bazel in different ways. Options that require a value
can be passed with either an equals sign or a space:

```
--&lt;option&gt;=&lt;value&gt;
--&lt;option&gt; &lt;value&gt;
```

Some options have a single character short form; in that case, the short form
has to be passed with a single dash and a space.

```
-&lt;short_form&gt; &lt;value&gt;
```

Boolean options can be enabled as follows:

```
--&lt;option&gt;
--&lt;option&gt;=[true|yes|1]
```

and disabled as follows:

```
--no&lt;option&gt;
--&lt;option&gt;=[false|no|0]
```

Tristate options are usually set to automatic by default, and can be
force-enabled as follows:

```
--&lt;option&gt;=[true|yes|1]
```

or force-disabled as follows:

```
--no&lt;option&gt;
--&lt;option&gt;=[false|no|0]
```

## Startup Options

Options that appear before the command and are parsed by the client:

`--[no]autodetect_server_javabase` default: "true"
:   When --noautodetect\_server\_javabase is passed, Bazel does not fall back to the local JDK for running the bazel server and instead exits.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE)

`--[no]batch` default: "false"
:   If set, Bazel will be run as just a client process without a server, instead of in the standard client/server mode. This is deprecated and will be removed, please prefer shutting down the server explicitly if you wish to avoid lingering servers.

    Tags:
    [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE), [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION), [`deprecated`](#metadata_tag_DEPRECATED)

`--[no]batch_cpu_scheduling` default: "false"
:   Only on Linux; use 'batch' CPU scheduling for Blaze. This policy is useful for workloads that are non-interactive, but do not want to lower their nice value. See 'man 2 sched\_setscheduler'. If false, then Bazel does not perform a system call.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--bazelrc=&lt;path&gt;` multiple uses are accumulated
:   The location of the user .bazelrc file containing default values of Bazel options.
    `/dev/null` indicates that all further `--bazelrc`s will be ignored, which is useful to
    disable the search for a user rc file, e.g. in release builds.

    This option can also be specified multiple times. e.g. with
    `--bazelrc=x.rc --bazelrc=y.rc --bazelrc=/dev/null --bazelrc=z.rc`.

    1. `x.rc` and `y.rc` are read.
    2. `z.rc` is ignored due to the prior `/dev/null`.
       If unspecified, Bazel uses the first `.bazelrc` file it finds in
       the following two locations: the workspace directory, then the user's home
       directory.

    Note: command line options will always supersede any option in bazelrc.

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

`--[no]block_for_lock` default: "true"
:   When --noblock\_for\_lock is passed, Bazel does not wait for a running command to complete, but instead exits immediately.

    Tags:
    [`eagerness_to_exit`](#effect_tag_EAGERNESS_TO_EXIT)

`--[no]client_debug` default: "false"
:   If true, log debug information from the client to stderr. Changing this option will not cause the server to restart.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING)

`--connect_timeout_secs=&lt;an integer&gt;` default: "30"
:   The amount of time the client waits for each attempt to connect to the server

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

:   The hash function to use when computing file digests.

    Tags:
    [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE), [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--experimental_cgroup_parent=&lt;path&gt;` default: see description
:   The cgroup where to start the bazel server as an absolute path. The server process will be started in the specified cgroup for each supported controller. For example, if the value of this flag is /build/bazel and the cpu and memory controllers are mounted respectively on /sys/fs/cgroup/cpu and /sys/fs/cgroup/memory, the server will be started in the cgroups /sys/fs/cgroup/cpu/build/bazel and /sys/fs/cgroup/memory/build/bazel.It is not an error if the specified cgroup is not writable for one or more of the controllers. This options does not have any effect on platforms that do not support cgroups.

    Tags:
    [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING), [`execution`](#effect_tag_EXECUTION)

`--[no]experimental_run_in_user_cgroup` default: "false"
:   If true, the Bazel server will be run with systemd-run, and the user will own the cgroup. This flag only takes effect on Linux.

    Tags:
    [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING), [`execution`](#effect_tag_EXECUTION)

`--extra_classpath=<a string&gt;` default: ""
:   A colon-separated list of classpath entries to be added to the classpath of the Bazel server.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--failure_detail_out=&lt;path&gt;` default: see description
:   If set, specifies a location to write a failure\_detail protobuf message if the server experiences a failure and cannot report it via gRPC, as normal. Otherwise, the location will be $&#123;OUTPUT\_BASE&#125;/failure\_detail.rawproto.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE)

`--[no]ignore_all_rc_files` default: "false"
:   Disables all rc files, regardless of the values of other rc-modifying flags, even if these flags come later in the list of startup options.

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

`--io_nice_level=&#123;-1,0,1,2,3,4,5,6,7&#125;` default: "-1"
:   Only on Linux; set a level from 0-7 for best-effort IO scheduling using the sys\_ioprio\_set system call. 0 is highest priority, 7 is lowest. The anticipatory scheduler may only honor up to priority 4. If set to a negative value, then Bazel does not perform a system call.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--local_startup_timeout_secs=&lt;an integer&gt;` default: "120"
:   The maximum amount of time the client waits to connect to the server

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--macos_qos_class=<a string&gt;` default: "default"
:   Sets the QoS service class of the bazel server when running on macOS. This flag has no effect on all other platforms but is supported to ensure rc files can be shared among them without changes. Possible values are: user-interactive, user-initiated, default, utility, and background.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--max_idle_secs=&lt;integer&gt;` default: "10800"
:   The number of seconds the build server will wait idling before shutting down. Zero means that the server will never shutdown. This is only read on server-startup, changing this option will not cause the server to restart.

    Tags:
    [`eagerness_to_exit`](#effect_tag_EAGERNESS_TO_EXIT), [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE)

`--output_base=&lt;path&gt;` default: see description
:   If set, specifies the output location to which all build output will be written. Otherwise, the location will be $&#123;OUTPUT\_ROOT&#125;/*blaze*$&#123;USER&#125;/$&#123;MD5\_OF\_WORKSPACE\_ROOT&#125;. Note: If you specify a different option from one to the next Bazel invocation for this value, you'll likely start up a new, additional Bazel server. Bazel starts exactly one server per specified output base. Typically there is one output base per workspace - however, with this option you may have multiple output bases per workspace and thereby run multiple builds for the same client on the same machine concurrently. See 'bazel help shutdown' on how to shutdown a Bazel server.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE)

`--output_user_root=&lt;path&gt;` default: see description
:   The user-specific directory beneath which all build outputs are written; by default, this is a function of $USER, but by specifying a constant, build outputs can be shared between collaborating users.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE)

`--[no]preemptible` default: "false"

    Tags:
    [`eagerness_to_exit`](#effect_tag_EAGERNESS_TO_EXIT)

`--[no]quiet` default: "false"
:   If true, no informational messages are emitted on the console, only errors. Changing this option will not cause the server to restart.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING)

`--server_jvm_out=&lt;path&gt;` default: see description
:   The location to write the server's JVM's output. If unset then defaults to a location in output\_base.

`--[no]shutdown_on_low_sys_mem` default: "false"
:   If max\_idle\_secs is set and the build server has been idle for a while, shut down the server when the system is low on free RAM. Linux and MacOS only.

    Tags:
    [`eagerness_to_exit`](#effect_tag_EAGERNESS_TO_EXIT), [`loses_incremental_state`](#effect_tag_LOSES_INCREMENTAL_STATE)

`--[no]system_rc` default: "true"
:   Whether or not to look for the system-wide bazelrc.

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

`--[no]unlimit_coredumps` default: "false"
:   Raises the soft coredump limit to the hard limit to make coredumps of the server (including the JVM) and the client possible under common conditions. Stick this flag in your bazelrc once and forget about it so that you get coredumps when you actually encounter a condition that triggers them.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--[no]windows_enable_symlinks` default: "false"
:   If true, real symbolic links will be created on Windows instead of file copying. Requires Windows developer mode to be enabled and Windows 10 version 1703 or greater.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--[no]workspace_rc` default: "true"
:   Whether or not to look for the workspace bazelrc file at `$workspace/.bazelrc`

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

Remote caching and execution options:

`--[no]experimental_remote_repo_contents_cache` default: "false"
:   If enabled, the remote cache will be used to store the results of reproducible repository
    rules. If a repository rule needs to be evaluated and its result is already in the remote
    cache, the contents of the repository will be kept in an in-memory file system and are
    only downloaded when needed, either by Bazel itself or an action that runs locally.

    Tags:
    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS)

Miscellaneous options, not otherwise categorized.:

`--host_jvm_args=&lt;jvm_arg&gt;` multiple uses are accumulated
:   Flags to pass to the JVM executing Blaze.

`--host_jvm_debug`
:   Convenience option to add some additional JVM startup flags, which cause the JVM to wait during startup until you connect from a JDWP-compliant debugger (like Eclipse) to port 5005.

    Expands to:

      `--host_jvm_args=-agentlib:jdwp=transport=dt_socket,server=y,address=5005`

`--server_javabase=&lt;jvm path&gt;` default: ""
:   Path to the JVM used to execute Bazel itself.

## Options Common to all Commands

Options that appear before the command and are parsed by the client:

`--distdir=<a path&gt;` multiple uses are accumulated
:   Additional places to search for archives before accessing the network to download them.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--[no]experimental_repository_cache_hardlinks` default: "false"
:   If set, the repository cache will hardlink the file in case of a cache hit, rather than copying. This is intended to save disk space.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--experimental_repository_downloader_retries=&lt;an integer&gt;` default: "5"
:   The maximum number of attempts to retry a download error. If set to 0, retries are disabled.

    Tags:
    [`experimental`](#metadata_tag_EXPERIMENTAL)

`--experimental_scale_timeouts=<a double&gt;` default: "1.0"
:   Scale all timeouts in Starlark repository rules by this factor. In this way, external repositories can be made working on machines that are slower than the rule author expected, without changing the source code

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--http_connector_attempts=&lt;an integer&gt;` default: "8"

`--http_connector_retry_max_timeout=&lt;An immutable length of time.&gt;` default: "0s"
:   The maximum timeout for http download retries. With a value of 0, no timeout maximum is defined.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--http_max_parallel_downloads=&lt;an integer&gt;` default: "8"
:   The maximum number parallel http downloads.

    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--http_timeout_scaling=<a double&gt;` default: "1.0"
:   Scale all timeouts related to http downloads by the given factor

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--repo_contents_cache=<a path&gt;` default: see description
:   Specifies the location of the repo contents cache, which contains fetched repo
    directories shareable across workspaces. An empty string as argument requests the repo
    contents cache to be disabled, otherwise the default of `&#123;--repository_cache&#125;/contents`
    is used. Note that this means setting `--repository_cache=` would by default disable the
    repo contents cache as well, unless `--repo_contents_cache=&#123;some_path&#125;` is also set.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--repo_contents_cache_gc_idle_delay=&lt;An immutable length of time.&gt;` default: "5m"
:   Specifies the amount of time the server must remain idle before garbage collection happens
    to the repo contents cache.

    it's garbage collected. If set to zero, only duplicate entries will be garbage collected.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--repository_cache=<a path&gt;` default: see description
:   Specifies the cache location of the downloaded values obtained
    during the fetching of external repositories. An empty string
    as argument requests the cache to be disabled,
    otherwise the default of `&#123;--output_user_root&#125;/cache/repos/v1` is used.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--[no]repository_disable_download` default: "false"
:   If set, downloading using `ctx.download&#123;,_and_extract&#125;` is not allowed during repository
    fetching. Note that network access is not completely disabled; ctx.execute could
    still run an arbitrary executable that accesses the Internet.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

Options that control build execution:

`--experimental_ui_max_stdouterr_bytes=&lt;an integer in (-1)-1073741819 range&gt;` default: "1048576"
:   The maximum size of the stdout / stderr files that will be printed to the console. -1 implies no limit.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

`--gc_churning_threshold=&lt;an integer in 0-100 range&gt;` default: "100"
:   At any point after an invocation has been running for at least one minute, if Blaze has spent at least this percentage of the invocation's wall time doing full GCs, Blaze will give up and fail with an OOM. A value of 100 effectively means to never give up for this reason.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--gc_churning_threshold_if_multiple_top_level_targets=&lt;an integer&gt;` default: "-1"
:   If set to a value in [0, 100] and this is a command that takes top-level targets (e.g. build but not query) and there are multiple such top-level targets, overrides --gc\_churning\_threshold. Useful to configure more aggressive OOMing behavior (i.e. a lower value than --gc\_churning\_threshold) when they are multiple top-level targets so that the invoker of Bazel can split and retry while still having less aggressive behavior when there is a single top-level target.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--gc_thrashing_threshold=&lt;an integer in 0-100 range&gt;` default: "100"
:   The percent of tenured space occupied (0-100) above which GcThrashingDetector considers memory pressure events against its limits (--gc\_thrashing\_limits). If set to 100, GcThrashingDetector is disabled.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

Options that configure the toolchain used for action execution:

`--[no]incompatible_enable_proto_toolchain_resolution` default: "true"
:   If true, proto lang rules define toolchains from protobuf repository.

    Tags:
    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--bep_maximum_open_remote_upload_files=&lt;an integer&gt;` default: "-1"
:   Maximum number of open files allowed during BEP artifact upload.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--[no]experimental_strict_repo_env` default: "false"
:   If true, repository rules and module extensions will only inherit `PATH`, `PATHEXT`
    (on Windows), and environment variables explicitly specified by `--repo_env`.

    Note that unless `--incompatible_repo_env_ignores_action_env` is true,
    `--action_env=NAME=VALUE` will also be included.

    Tags:
    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]incompatible_repo_env_ignores_action_env` default: "true"
:   If true, <code>--action\_env=NAME=VALUE</code> will no longer affect repository rule and module extension environments.

    Tags:
    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

`--remote_download_all`
:   Downloads all remote outputs to the local machine. This flag is an alias for --remote\_download\_outputs=all.

    Expands to:

      `--remote_download_outputs=all`

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--remote_download_minimal`
:   Does not download any remote build outputs to the local machine. This flag is an alias for --remote\_download\_outputs=minimal.

    Expands to:

      `--remote_download_outputs=minimal`

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--remote_download_outputs=&lt;all, minimal or toplevel&gt;` default: "toplevel"
:   If set to 'minimal' doesn't download any remote build outputs to the local machine, except the ones required by local actions. If set to 'toplevel' behaves like 'minimal' except that it also downloads outputs of top level targets to the local machine. Both options can significantly reduce build times if network bandwidth is a bottleneck.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--remote_download_symlink_template=<a string&gt;` default: ""
:   Instead of downloading remote build outputs to the local machine, create symbolic links. The target of the symbolic links can be specified in the form of a template string. This template string may contain &#123;hash&#125; and &#123;size\_bytes&#125; that expand to the hash of the object and the size in bytes, respectively. These symbolic links may, for example, point to a FUSE file system that loads objects from the CAS on demand.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--remote_download_toplevel`
:   Only downloads remote outputs of top level targets to the local machine. This flag is an alias for --remote\_download\_outputs=toplevel.

    Expands to:

      `--remote_download_outputs=toplevel`

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--repo_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies additional environment variables to be available only for repository rules. Note that repository rules see the full environment anyway, but in this way variables can be set via command-line flags and <code>.bazelrc</code> entries. The special syntax <code>=NAME</code> can be used to explicitly unset a variable. The string <code>%bazel\_workspace%</code> in a value will be replaced with the absolute path of the workspace as printed by <code>bazel info workspace</code>.

    Tags:
    [`action_command_lines`](#effect_tag_ACTION_COMMAND_LINES)

Options that affect how strictly Bazel enforces valid build inputs (rule definitions, flag combinations, etc.):

`--[no]allow_experimental_loads` default: "false"
:   If enabled, issue only a warning instead of an error for loads of experimental .bzls.

    Tags:
    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

`--[no]check_bzl_visibility` default: "true"
:   If disabled, .bzl load visibility errors are demoted to warnings.

    Tags:
    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

`--[no]incompatible_enforce_starlark_utf8` default: "warning"
:   If enabled (or set to 'error'), fail if Starlark files are not UTF-8 encoded. If set to 'warning', emit a warning instead. If set to 'off', Bazel assumes that Starlark files are UTF-8 encoded but does not verify this assumption. Note that Starlark files which are not UTF-8 encoded can cause Bazel to behave inconsistently.

    Tags:
    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

This option affects semantics of the Starlark language or the build API accessible to BUILD files, .bzl files, or WORKSPACE files.:

`--[no]experimental_bzl_visibility` default: "true"
:   If enabled, adds a `visibility()` function that .bzl files may call during top-level evaluation to set their visibility for the purpose of load() statements.

    Tags:
    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]experimental_cc_shared_library` default: "false"

`--incompatible_autoload_externally=&lt;comma-separated set of options&gt;` default: ""
:   A comma-separated list of rules (or other symbols) that were previously part of Bazel and which are now to be retrieved from their respective external repositories. This flag is intended to be used to facilitate migration of rules out of Bazel. See also https://github.com/bazelbuild/bazel/issues/23043.
    A symbol that is autoloaded within a file behaves as if its built-into-Bazel definition were replaced by its canonical new definition in an external repository. For a BUILD file, this essentially means implicitly adding a load() statement. For a .bzl file, it's either a load() statement or a change to a field of the `native` object, depending on whether the autoloaded symbol is a rule.
    Bazel maintains a hardcoded list of all symbols that may be autoloaded; only those symbols may appear in this flag. For each symbol, Bazel knows the new definition location in an external repository, as well as a set of special-cased repositories that must not autoload it to avoid creating cycles.
    A list item of "+foo" in this flag causes symbol foo to be autoloaded, except in foo's exempt repositories, within which the Bazel-defined version of foo is still available.
    A list item of "foo" triggers autoloading as above, but the Bazel-defined version of foo is not made available to the excluded repositories. This ensures that foo's external repository does not depend on the old Bazel implementation of foo
    A list item of "-foo" does not trigger any autoloading, but makes the Bazel-defined version of foo inaccessible throughout the workspace. This is used to validate that the workspace is ready for foo's definition to be deleted from Bazel.
    If a symbol is not named in this flag then it continues to work as normal -- no autoloading is done, nor is the Bazel-defined version suppressed. For configuration see https://github.com/bazelbuild/bazel/blob/master/src/main/java/com/google/devtools/build/lib/packages/AutoloadSymbols.java As a shortcut also whole repository may be used, for example +@rules\_python will autoload all Python rules.

Options relating to Bzlmod output and semantics:

`--allow_yanked_versions=<a string&gt;` multiple uses are accumulated
:   Specified the module versions in the form of
    `&#123;module1&#125;@&#123;version1&#125;,module2@&#123;version2&#125;` that will be allowed in the resolved
    dependency graph even if they are declared yanked in the registry where they come
    from (if they are not coming from a [`NonRegistryOverride`](https://github.com/bazelbuild/bazel/blob/master/src/main/java/com/google/devtools/build/lib/bazel/bzlmod/NonRegistryOverride.java)).
    Otherwise, yanked versions will cause the resolution to fail. You can also define allowed
    yanked versions with the `BZLMOD_ALLOW_YANKED_VERSIONS` environment variable. You can
    disable this check by using the keyword `all` (not recommended).

`--check_direct_dependencies=&lt;off, warning or error&gt;` default: "warning"

    the `MODULE.bazel` of the root module. Note that, those dev dependencies are always
    ignored in the `MODULE.bazel` if it's not the root module regardless of the value
    of this flag.

`--lockfile_mode=&lt;off, update, refresh or error&gt;` default: "update"
:   Specifies how and whether or not to use the lockfile. Valid values are `update` to use the lockfile and update it if there are changes, `refresh` to additionally refresh mutable information (yanked versions and previously missing modules) from remote registries from time to time, `error` to use the lockfile but throw an error if it's not up-to-date, or `off` to neither read from or write to the lockfile.

`--module_mirrors=<a '[name=]value1[,..,valueN]' assignment&gt;` multiple uses are accumulated
:   Specifies URLs under which the source URLs of Bazel modules can be found, in addition
    to and taking precedence over any registry-provided mirror URLs. This flag can be
    specified per-registry using the syntax
    `--module_mirrors=&lt;registry&gt;=&lt;mirror1&gt;[,&lt;mirror2&gt;,...]` (e.g.,
    `--module_mirrors=https://bcr.bazel.build=https://mirror.example.com`). It can also
    be specified as a comma-separated list of mirror URLs that applies to all registries that
    don't have an explicit list (e.g., `--module_mirrors=https://mirror1,https://mirror2`).
    Set this to an empty value to disable the use of any mirrors not specified by the
    registries. Later uses of this flag override earlier ones with the same (or no) registry.
    The default set of mirrors may change over time, but all downloads from mirrors are
    verified by hashes stored in the registry (and thus pinned by the lockfile).

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS)

`--override_module=&lt;an equals-separated mapping of module name to path&gt;` multiple uses are accumulated
:   Override a module with a local path in the form of `&#123;module name&#125;=&#123;path&#125;`. If the given
    path is an absolute path, it will be used as it is. If the given path is a
    relative path, it is relative to the current working directory. If the given path
    starts with `%workspace%`, it is relative to the workspace root, which is the
    output of `bazel info workspace`. If the given path is empty, then remove any
    previous overrides.

`--registry=<a string&gt;` multiple uses are accumulated
:   Specifies the registries to use to locate Bazel module dependencies. The order is important: modules will be looked up in earlier registries first, and only fall back to later registries when they're missing from the earlier ones.

    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

`--vendor_dir=<a path&gt;` default: see description

`--gc_thrashing_limits=&lt;comma separated pairs of &lt;period&gt;:&lt;count&gt;&gt;` default: "1s:2,20s:3,1m:5"
:   Limits which, if reached, cause GcThrashingDetector to crash Bazel with an OOM. Each limit is specified as &lt;period&gt;:&lt;count&gt; where period is a duration and count is a positive integer. If more than --gc\_thrashing\_threshold percent of tenured space (old gen heap) remains occupied after &lt;count&gt; consecutive full GCs within &lt;period&gt;, an OOM is triggered. Multiple limits can be specified separated by commas.

:   Flag for advanced configuration of Bazel's internal Skyframe engine. If Bazel detects its retained heap percentage usage exceeds the threshold set by --skyframe\_high\_water\_mark\_threshold, when a full GC event occurs, it will drop unnecessary temporary Skyframe state, up to this many times per invocation.

If Bazel detects its retained heap percentage usage is at least this threshold, it will drop unnecessary temporary Skyframe state. Tweaking this may let you mitigate wall time impact of GC thrashing, when the GC thrashing is (i) caused by the memory usage of this temporary state and (ii) more costly than reconstituting the state when it is needed.

The server implementation needs to support the new `http_header_url:&lt;url-index&gt;:&lt;header-key&gt;` qualifier where the `&lt;url-index&gt;` is a 0-based position of the URL inside the FetchBlobRequest's `uris` field. The URL-specific headers should take precedence over the global headers.

`--experimental_remote_failure_rate_threshold=&lt;an integer in 0-100 range&gt;` default: "10"
:   Sets the allowed number of failure rate in percentage for a specific time window after which it stops calling to the remote cache/executor. By default the value is 10. Setting this to 0 means no limitation.

    [`execution`](#effect_tag_EXECUTION)

`--experimental_remote_failure_window_interval=&lt;An immutable length of time.&gt;` default: "60s"
:   The interval in which the failure rate of the remote requests are computed. On zero or negative value the failure duration is computed the whole duration of the execution.Following units can be used: Days (d), hours (h), minutes (m), seconds (s), and milliseconds (ms). If the unit is omitted, the value is interpreted as seconds.

    [`execution`](#effect_tag_EXECUTION)

`--[no]experimental_remote_mark_tool_inputs` default: "false"
:   If set to true, Bazel will mark inputs as tool inputs for the remote executor. This can be used to implement remote persistent workers.

`--experimental_remote_output_service=<a string&gt;` default: see description
:   HOST or HOST:PORT of a remote output service endpoint. The supported schemas are grpc, grpcs (grpc with TLS enabled) and unix (local UNIX sockets). If no schema is provided Bazel will default to grpcs. Specify grpc:// or unix: schema to disable TLS.

`--experimental_remote_output_service_output_path_prefix=<a string&gt;` default: ""
:   The path under which the contents of output directories managed by the --experimental\_remote\_output\_service are placed. The actual output directory used by a build will be a descendant of this path and determined by the output service.

`--[no]experimental_remote_require_cached` default: "false"
:   If set to true, enforce that all actions that can run remotely are cached, or else fail the build. This is useful to troubleshoot non-determinism issues as it allows checking whether actions that should be cached are actually cached without spuriously injecting new results into the cache.

`--experimental_remote_scrubbing_config=&lt;Converts to a Scrubber&gt;` default: see description
:   Enables remote cache key scrubbing with the supplied configuration file, which must be a protocol buffer in text format (see src/main/protobuf/remote\_scrubbing.proto).

    This feature is intended to facilitate sharing a remote/disk cache between actions executing on different platforms but targeting the same platform. It should be used with extreme care, as improper settings may cause accidental sharing of cache entries and result in incorrect builds.

    Scrubbing does not affect how an action is executed, only how its remote/disk cache key is computed for the purpose of retrieving or storing an action result. Scrubbed actions are incompatible with remote execution, and will always be executed locally instead.

    Modifying the scrubbing configuration does not invalidate outputs present in the local filesystem or internal caches; a clean build is required to reexecute affected actions.

    In order to successfully use this feature, you likely want to set a custom --host\_platform together with --experimental\_platform\_in\_output\_dir (to normalize output prefixes).

`--[no]guard_against_concurrent_changes` default: "lite"
:   Set this to 'full' to enable checking the ctime of all input files of an action before uploading it to a remote cache. There may be cases where the Linux kernel delays writing of files, which could cause false positives. The default is 'lite', which only checks source files in the main repository. Setting this to 'off' disables all checks. This is not recommended, as the cache may be polluted when a source file is changed while an action that takes it as an input is executing.

    [`execution`](#effect_tag_EXECUTION)

`--[no]incompatible_remote_local_fallback_for_remote_cache` default: "false"
:   Whether --remote\_local\_fallback applies to --remote\_cache.

`--[no]remote_accept_cached` default: "true"
:   Whether to accept remotely cached action results.

`--remote_build_event_upload=&lt;all or minimal&gt;` default: "minimal"
:   If set to 'all', all local outputs referenced by BEP are uploaded to remote cache.
    If set to 'minimal', local outputs referenced by BEP are not uploaded to the remote cache, except for files that are important to the consumers of BEP (e.g. test logs and timing profile). bytestream:// scheme is always used for the uri of files even if they are missing from remote cache.
    Default to 'minimal'.

`--remote_bytestream_uri_prefix=<a string&gt;` default: see description
:   The hostname and instance name to be used in bytestream:// URIs that are written into build event streams. This option can be set when builds are performed using a proxy, which causes the values of --remote\_executor and --remote\_instance\_name to no longer correspond to the canonical name of the remote execution service. When not set, it will default to "$&#123;hostname&#125;/$&#123;instance\_name&#125;".

`--remote_cache=<a string&gt;` default: see description
:   A URI of a caching endpoint. The supported schemas are http, https, grpc, grpcs (grpc with TLS enabled) and unix (local UNIX sockets). If no schema is provided Bazel will default to grpcs. Specify grpc://, http:// or unix: schema to disable TLS. See https://bazel.build/remote/caching

`--[no]remote_cache_async` default: "true"
:   If true, uploading of action results to a disk or remote cache will happen in the background instead of blocking the completion of an action. Some actions are incompatible with background uploads, and may still block even when this flag is set.

`--[no]remote_cache_compression` default: "false"
:   If enabled, compress/decompress cache blobs with zstd when their size is at least --experimental\_remote\_cache\_compression\_threshold.

`--remote_cache_header=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specify a header that will be included in cache requests: --remote\_cache\_header=Name=Value. Multiple headers can be passed by specifying the flag multiple times. Multiple values for the same name will be converted to a comma-separated list.

`--remote_default_exec_properties=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Set the default exec properties to be used as the remote execution platform if an execution platform does not already set exec\_properties.

    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--remote_downloader_header=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specify a header that will be included in remote downloader requests: --remote\_downloader\_header=Name=Value. Multiple headers can be passed by specifying the flag multiple times. Multiple values for the same name will be converted to a comma-separated list.

`--remote_exec_header=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specify a header that will be included in execution requests: --remote\_exec\_header=Name=Value. Multiple headers can be passed by specifying the flag multiple times. Multiple values for the same name will be converted to a comma-separated list.

`--remote_execution_priority=&lt;an integer&gt;` default: "0"
:   The relative priority of actions to be executed remotely. The semantics of the particular priority values are server-dependent.

`--remote_executor=<a string&gt;` default: see description
:   HOST or HOST:PORT of a remote execution endpoint. The supported schemas are grpc, grpcs (grpc with TLS enabled) and unix (local UNIX sockets). If no schema is provided Bazel will default to grpcs. Specify grpc:// or unix: schema to disable TLS.

`--remote_grpc_log=<a path&gt;` default: see description
:   If specified, a path to a file to log gRPC call related details. This log consists of a sequence of serialized com.google.devtools.build.lib.remote.logging.RemoteExecutionLog.LogEntry protobufs with each message prefixed by a varint denoting the size of the following serialized protobuf message, as performed by the method LogEntry.writeDelimitedTo(OutputStream).

`--remote_header=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specify a header that will be included in requests: --remote\_header=Name=Value. Multiple headers can be passed by specifying the flag multiple times. Multiple values for the same name will be converted to a comma-separated list.

`--remote_instance_name=<a string&gt;` default: ""
:   Value to pass as instance\_name in the remote execution API.

`--[no]remote_local_fallback` default: "false"
:   Whether to fall back to standalone local execution strategy if remote execution fails.

`--remote_local_fallback_strategy=<a string&gt;` default: "local"
:   Deprecated. See https://github.com/bazelbuild/bazel/issues/7480 for details.

`--remote_max_concurrency_per_connection=&lt;an integer&gt;` default: "100"
:   Limit the max number of concurrent requests per gRPC connection. By default the value is 100.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--remote_max_connections=&lt;an integer&gt;` default: "100"
:   Limit the max number of concurrent connections to remote cache/executor. By default the value is 100. Setting this to 0 means no limitation.
    For HTTP remote cache, one TCP connection could handle one request at one time, so Bazel could make up to --remote\_max\_connections concurrent requests.
    For gRPC remote cache/executor, one gRPC channel could usually handle 100+ concurrent requests (controlled by --remote\_max\_concurrency\_per\_connection), so Bazel could make around `--remote_max_connections * 100` concurrent requests.

    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--remote_proxy=<a string&gt;` default: see description
:   Connect to the remote cache through a proxy. Currently this flag can only be used to configure a Unix domain socket (unix:/path/to/socket).

`--remote_result_cache_priority=&lt;an integer&gt;` default: "0"
:   The relative priority of remote actions to be stored in remote cache. The semantics of the particular priority values are server-dependent.

`--remote_retries=&lt;an integer&gt;` default: "5"
:   The maximum number of attempts to retry a transient error. If set to 0, retries are disabled.

`--remote_retry_max_delay=&lt;An immutable length of time.&gt;` default: "5s"
:   The maximum backoff delay between remote retry attempts. Following units can be used: Days (d), hours (h), minutes (m), seconds (s), and milliseconds (ms). If the unit is omitted, the value is interpreted as seconds.

`--remote_timeout=&lt;An immutable length of time.&gt;` default: "60s"
:   The maximum amount of time to wait for remote execution and cache calls. For the REST cache, this is both the connect and the read timeout. Following units can be used: Days (d), hours (h), minutes (m), seconds (s), and milliseconds (ms). If the unit is omitted, the value is interpreted as seconds.

`--[no]remote_upload_local_results` default: "true"
:   Whether to upload locally executed action results to the remote cache if the remote cache supports it and the user is authorized to do so.

`--[no]remote_verify_downloads` default: "true"
:   If set to true, Bazel will compute the hash sum of all remote downloads and discard the remotely cached values if they don't match the expected value.

Miscellaneous options, not otherwise categorized.:

`--build_metadata=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Custom key-value string pairs to supply in a build event.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--color=&lt;yes, no or auto&gt;` default: "auto"
:   Use terminal controls to colorize output.

`--config=<a string&gt;` multiple uses are accumulated
:   Selects additional config sections from the rc files; for every &lt;command&gt;, it also pulls in the options from &lt;command&gt;:&lt;config&gt; if such a section exists; if this section doesn't exist in any .rc file, Blaze fails with an error. The config sections and flag combinations they are equivalent to are located in the tools/\*.blazerc config files.

`--credential_helper=&lt;Path to a credential helper. It may be absolute, relative to the PATH environment variable, or %workspace%-relative. The path be optionally prefixed by a scope followed by an '='. The scope is a domain name, optionally with a single leading '*' wildcard component. A helper applies to URIs matching its scope, with more specific scopes preferred. If a helper has no scope, it applies to every URI.&gt;` multiple uses are accumulated
:   Configures a credential helper conforming to the [Credential Helper Specification](https://github.com/EngFlow/credential-helper-spec)
    to use for retrieving authorization credentials for repository
    fetching, remote caching and execution, and the build event service.

    Credentials supplied by a helper take precedence over credentials supplied by
    `--google_default_credentials`, `--google_credentials`, a `.netrc` file, or the
    auth parameter to `repository_ctx.download()` and
    `repository_ctx.download_and_extract()`.

    May be specified multiple times to set up multiple helpers.

    See [Configuring Bazel's Credential Helper - Engflow Blog](https://blog.engflow.com/2023/10/09/configuring-bazels-credential-helper/) for instructions.

`--credential_helper_cache_duration=&lt;An immutable length of time.&gt;` default: "30m"
:   How long to cache credentials for if the credential helper doesn't return an expiration time. Changing the value of this flag clears the cache.

`--credential_helper_timeout=&lt;An immutable length of time.&gt;` default: "10s"
:   Configures the timeout for a credential helper.

    Credential helpers failing to respond within this timeout will fail the invocation.

`--curses=&lt;yes, no or auto&gt;` default: "auto"
:   Use terminal cursor controls to minimize scrolling output.

`--disk_cache=<a path&gt;` default: see description
:   A path to a directory where Bazel can read and write actions and action outputs. If the directory does not exist, it will be created.

`--[no]enable_platform_specific_config` default: "false"
:   If true, Bazel picks up host-OS-specific config lines from bazelrc files. For example, if the host OS is Linux and you run bazel build, Bazel picks up lines starting with build:linux. Supported OS identifiers are linux, macos, windows, freebsd, and openbsd. Enabling this flag is equivalent to using --config=linux on Linux, --config=windows on Windows, etc.

`--experimental_action_cache_gc_idle_delay=&lt;An immutable length of time.&gt;` default: "5m"
:   How long the server must remain idle before a garbage collection of the action cache is attempted. Ineffectual unless --experimental\_action\_cache\_gc\_max\_age is nonzero.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--experimental_action_cache_gc_max_age=&lt;An immutable length of time.&gt;` default: "0"
:   If set to a nonzero value, the action cache will be periodically garbage collected to remove entries older than this age. Garbage collection occurs in the background once the server has become idle, as determined by the --experimental\_action\_cache\_gc\_idle\_delay and --experimental\_action\_cache\_gc\_threshold flags.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--experimental_action_cache_gc_threshold=&lt;an integer in 0-100 range&gt;` default: "10"

`--experimental_disk_cache_gc_idle_delay=&lt;An immutable length of time.&gt;` default: "5m"
:   How long the server must remain idle before a garbage collection of the disk cache occurs. To specify the garbage collection policy, set --experimental\_disk\_cache\_gc\_max\_size and/or --experimental\_disk\_cache\_gc\_max\_age.

`--experimental_disk_cache_gc_max_age=&lt;An immutable length of time.&gt;` default: "0"
:   If set to a positive value, the disk cache will be periodically garbage collected to remove entries older than this age. If set in conjunction with --experimental\_disk\_cache\_gc\_max\_size, both criteria are applied. Garbage collection occurrs in the background once the server has become idle, as determined by the --experimental\_disk\_cache\_gc\_idle\_delay flag.

`--experimental_disk_cache_gc_max_size=<a size in bytes, optionally followed by a K, M, G or T multiplier&gt;` default: "0"
:   If set to a positive value, the disk cache will be periodically garbage collected to stay under this size. If set in conjunction with --experimental\_disk\_cache\_gc\_max\_age, both criteria are applied. Garbage collection occurrs in the background once the server has become idle, as determined by the --experimental\_disk\_cache\_gc\_idle\_delay flag.

`--[no]experimental_enable_thread_dump` default: "false"
:   Whether to enable thread dumps. If true, Bazel will dump the state of all threads (including virtual threads) to a file every --experimental\_thread\_dump\_interval, or after action execution being inactive for --experimental\_thread\_dump\_action\_execution\_inactivity\_duration. The dumps will be written to the &lt;output\_base&gt;/server/thread\_dumps/ directory.

    Tags:
    [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING)

`--experimental_install_base_gc_max_age=&lt;An immutable length of time.&gt;` default: "30d"

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--experimental_thread_dump_action_execution_inactivity_duration=&lt;An immutable length of time.&gt;` default: "0"
:   Dump the threads when action execution being inactive for this duration. If zero, no thread dumps are written for action execution being inactive.

    Tags:
    [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING)

`--experimental_thread_dump_interval=&lt;An immutable length of time.&gt;` default: "0"
:   How often to dump the threads periodically. If zero, no thread dumps are written periodically.

    Tags:
    [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING)

`--[no]experimental_windows_watchfs` default: "false"
:   If true, experimental Windows support for --watchfs is enabled. Otherwise --watchfsis a non-op on Windows. Make sure to also enable --watchfs.

`--google_auth_scopes=&lt;comma-separated list of options&gt;` default: "https://www.googleapis.com/auth/cloud-platform"
:   A comma-separated list of Google Cloud authentication scopes.

`--google_credentials=<a string&gt;` default: see description
:   Specifies the file to get authentication credentials from. See https://cloud.google.com/docs/authentication for details.

`--[no]google_default_credentials` default: "false"
:   Whether to use 'Google Application Default Credentials' for authentication.
    See [Authentication methods at Google - Google Cloud](https://cloud.google.com/docs/authentication) for details.
    Disabled by default.

`--grpc_keepalive_time=&lt;An immutable length of time.&gt;` default: "60s"
:   Configures keep-alive pings for outgoing gRPC connections. If this is set, then Bazel
    sends pings after this much time of no read operations on the connection, but
    only if there is at least one pending gRPC call. The value 0 disables the keep-alives.

`--grpc_keepalive_timeout=&lt;An immutable length of time.&gt;` default: "20s"
:   Configures a keep-alive timeout for outgoing gRPC connections. If keep-alive pings are
    enabled with `--grpc_keepalive_time`, then Bazel times out a connection if it does
    not receive a ping reply after this much time. Times are treated as second
    granularity; it is an error to set a value less than one second. If keep-alive
    pings are disabled, then this setting is ignored.

`--[no]incompatible_disable_non_executable_java_binary` default: "false"
:   If true, java\_binary is always executable. create\_executable attribute is removed.

`--inject_repository=&lt;an equals-separated mapping of repository name to path&gt;` multiple uses are accumulated
:   Adds a new repository with a local path in the form of `&#123;repository name&#125;=&#123;path&#125;`. This
    only takes effect with `--enable_bzlmod` and is equivalent to adding a
    corresponding `local_repository` to the root module's `MODULE.bazel` file via
    `use_repo_rule`. If the given path is an absolute path, it will be used as it is.
    If the given path is a relative path, it is relative to the current working
    directory. If the given path starts with `%workspace%`, it is relative to the
    workspace root, which is the output of `bazel info workspace`. If the given path
    is empty, then remove any previous injections.

`--invocation_id=<a UUID&gt;` default: ""
:   Unique identifier, in UUID format, for the command being run. If explicitly specified uniqueness must be ensured by the caller. The UUID is printed to stderr, the BEP and remote execution protocol.

    [`bazel_monitoring`](#effect_tag_BAZEL_MONITORING), [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--override_repository=&lt;an equals-separated mapping of repository name to path&gt;` multiple uses are accumulated
:   Override a repository with a local path in the form of `&#123;repository name&#125;=&#123;path&#125;`,
    where the repository name can be either a canonical name or an apparent name from the
    point of view of the main repository.

    Note that if this is flag is used to override a module's repository, changes to the
    MODULE.bazel file will not be effective if the module is obtained from a registry. Use
    `--override_module` instead to for that purpose.

    If the given path is an absolute path, it will be used as it is. If the given path is a
    relative path, it is relative to the current working directory. If the given path starts
    with `%workspace%`, it is relative to the workspace root, which is the output of `bazel info workspace`. If the given path is empty, then remove any previous overrides.

`--[no]progress_in_terminal_title` default: "false"
:   Show the command progress in the terminal title. Useful to see what bazel is doing when having multiple terminal tabs.

`--[no]show_progress` default: "true"
:   Display progress messages during a build.

`--show_progress_rate_limit=<a double&gt;` default: "0.2"
:   Minimum number of seconds between progress messages in the output.

`--[no]show_timestamps` default: "false"
:   Include timestamps in messages

`--tls_certificate=<a string&gt;` default: see description
:   Specify a path to a TLS certificate that is trusted to sign server certificates.

`--tls_client_certificate=<a string&gt;` default: see description
:   Specify the TLS client certificate to use; you also need to provide a client key to enable client authentication.

`--tls_client_key=<a string&gt;` default: see description
:   Specify the TLS client key to use; you also need to provide a client certificate to enable client authentication.

`--ui_actions_shown=&lt;an integer&gt;` default: "8"
:   Number of concurrent actions shown in the detailed progress bar; each action is shown on a separate line. The progress bar always shows at least one one, all numbers less than 1 are mapped to 1.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]watchfs` default: "false"
:   On Linux/macOS: If true, bazel tries to use the operating system's file watch service for local changes instead of scanning every file for a change. On Windows: this flag currently is a non-op but can be enabled in conjunction with --experimental\_windows\_watchfs. On any OS: The behavior is undefined if your workspace is on a network file system, and files are edited on a remote machine.

## Aquery Options

Inherits all options from [build](#build).

Options relating to query output and semantics:

`--aspect_deps=&lt;off, conservative or precise&gt;` default: "conservative"
:   How to resolve aspect dependencies when the output format is one of &#123;xml,proto,record&#125;. 'off' means no aspect dependencies are resolved, 'conservative' (the default) means all declared aspect dependencies are added regardless of whether they are given the rule class of direct dependencies, 'precise' means that only those aspects are added that are possibly active given the rule class of the direct dependencies. Note that precise mode requires loading other packages to evaluate a single target thus making it slower than the other modes. Also note that even precise mode is not completely precise: the decision whether to compute an aspect is decided in the analysis phase, which is not run during 'bazel query'.

    Tags:
    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

`--[no]consistent_labels` default: "false"
:   If enabled, every query command emits labels as if by the Starlark <code>str</code> function applied to a <code>Label</code> instance. This is useful for tools that need to match the output of different query commands and/or labels emitted by rules. If not enabled, output formatters are free to emit apparent repository names (relative to the main repository) instead to make the output more readable.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]graph:factored` default: "true"
:   If true, then the graph will be emitted 'factored', i.e. topologically-equivalent nodes will be merged together and their labels concatenated. This option is only applicable to --output=graph.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--graph:node_limit=&lt;an integer&gt;` default: "512"
:   The maximum length of the label string for a graph node in the output. Longer labels will be truncated; -1 means no truncation. This option is only applicable to --output=graph.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]implicit_deps` default: "true"
:   If enabled, implicit dependencies will be included in the dependency graph over which the query operates. An implicit dependency is one that is not explicitly specified in the BUILD file but added by bazel. For cquery, this option controls filtering resolved toolchains.

    Tags:
    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

:   Include the content of the param files used in the command (potentially large). Note: Enabling this flag will automatically enable the --include\_commandline flag.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]include_pruned_inputs` default: "true"
:   Includes action inputs that were pruned during action execution. Only affects actions that discover inputs and have been executed in a previous invocation. Only takes effect if --include\_artifacts is also set.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]incompatible_package_group_includes_double_slash` default: "true"

:   If set and --universe\_scope is unset, then a value of --universe\_scope will be inferred as the list of unique target patterns in the query expression. Note that the --universe\_scope value inferred for a query expression that uses universe-scoped functions (e.g.`allrdeps`) may not be what you want, so you should use this option only if you know what you are doing. See https://bazel.build/reference/query#sky-query for details and examples. If --universe\_scope is set, then this option's value is ignored. Note: this option applies only to `query` (i.e. not `cquery`).

`--[no]tool_deps` default: "true"
:   Query: If disabled, dependencies on 'exec configuration' will not be included in the dependency graph over which the query operates. An 'exec configuration' dependency edge, such as the one from any 'proto\_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same 'target' program.
    Cquery: If disabled, filters out all configured targets which cross an execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the exec configuration, only exec configured targets will be returned. This option will NOT exclude resolved toolchains.

    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

`--universe_scope=&lt;comma-separated list of options&gt;` default: ""
:   A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands.
    For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.

`--modify_execution_info=&lt;regex=[+-]key,regex=[+-]key,...&gt;` multiple uses are accumulated
:   Add or remove keys from an action's execution info based on action mnemonic.
    Applies only to actions which support execution info. Many common actions
    support execution info, e.g. Genrule, CppCompile, Javac, StarlarkAction,
    TestRunner. When specifying multiple values, order matters because
    many regexes may apply to the same mnemonic.

    Syntax: `regex=[+-]key,regex=[+-]key,...`.

    Examples:

    * `.*=+x,.*=-y,.*=+z` adds `x` and `z` to, and removes `y` from, the execution info for all actions.
    * `Genrule=+requires-x` adds `requires-x` to the execution info for all Genrule actions.
    * `(?!Genrule).*=-requires-x` removes `requires-x` from the execution info for all non-Genrule actions.

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--action_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies the set of environment variables available to actions with target

`--runs_per_test=<a positive integer or test_regex@runs. This flag may be passed more than once&gt;` multiple uses are accumulated
:   Specifies number of times to run each test. If any of those attempts fail for any
    reason, the whole test is considered failed. Normally the value specified is
    just an integer.

    Example: `--runs_per_test=3` will run all tests 3 times.

    Alternate syntax: `regex_filter@runs_per_test`. Where `runs_per_test` stands for
    an integer value and `regex_filter` stands for a list of include and exclude
    regular expression patterns (Also see --instrumentation\_filter).

    Example: `--runs_per_test=//foo/.*,-//foo/bar/.*@3` runs all tests in `//foo/` except
    those under `//foo/bar` three times. This option can be passed multiple times. The most
    recently passed argument that matches takes precedence. If nothing matches,
    the test is only run once.

`--test_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies additional environment variables to be injected into the test runner
    environment. Variables can be either specified by `name`, in which
    case its value will be read from the Bazel client environment, or by the
    `name=value` pair.
    Previously set variables can be unset via `=name`.
    This option can be used multiple times to specify several variables.
    Used only by the 'bazel test' command.

    positive integer value is specified it will override all categories. If 4
    comma-separated integers are specified, they will override the timeouts for
    `short`, `moderate`, `long` and `eternal` (in that order). In either form, a value of
    -1 tells blaze to use its default timeouts for that category.

In particular, it does not understand dynamic #include directives and ignores preprocessor conditional logic. Use at your own risk. Any issues relating to this flag that are filed will be closed. At Google without this flag your build will most likely fail.

Options that affect the verbosity, format or location of logging:

`--toolchain_resolution_debug=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths&gt;` default: "-.\*"
:   Print debug information during toolchain resolution. The flag takes a regex, which is checked against toolchain types and specific targets to see which to debug. Multiple regexes may be separated by commas, and then each regex is checked separately. Note: The output of this flag is very complex and will likely only be useful to experts in toolchain resolution.

Miscellaneous options, not otherwise categorized.:

`--[no]cache_test_results` [`-t`] default: "auto"
:   If set to `auto`, Bazel reruns a test if and only if:

    1. Bazel detects changes in the test or its dependencies,
    2. The test is marked as `external`,
    3. Multiple test runs were requested with `--runs_per_test`, or
    4. The test previously failed.
       If set to `yes`, Bazel caches all test results except for tests marked as
       `external`. If set to `no`, Bazel does not cache any test results.

`--[no]experimental_cancel_concurrent_tests` default: "never"
:   If `on_failed` or `on_passed`, then Blaze will cancel concurrently running tests on the first
    successful run with that result. This is only useful in combination with

    supports sharding by touching the file at the path in `TEST_SHARD_STATUS_FILE`.
    If false, a test runner that does not support sharding will lead to all tests

:   If true, any shard in which at least one run/attempt passes and at least one run/attempt fails gets a FLAKY status.

`--shell_executable=<a path&gt;` default: see description
:   Absolute path to the shell executable for Bazel to use. If this is unset, but the
    `BAZEL_SH` environment variable is set on the first Bazel invocation (that starts
    up a Bazel server), Bazel uses that. If neither is set, Bazel uses a hard-coded
    default path depending on the operating system it runs on;

    * Windows: `c:/msys64/usr/bin/bash.exe`
    * FreeBSD: `/usr/local/bin/bash`
    * All others: `/bin/bash`.

    If multiple tests are executed, each of them will receive identical arguments.
    Used only by the `bazel test` command.

`--test_filter=<a string&gt;` default: see description
:   Specifies a filter to forward to the test framework. Used to limit the tests run. Note that this does not affect which targets are built.

`--test_result_expiration=&lt;an integer&gt;` default: "-1"
:   This option is deprecated and has no effect.

`--[no]test_runner_fail_fast` default: "false"
:   Forwards fail fast option to the test runner. The test runner should stop execution upon first failure.

`--test_sharding_strategy=&lt;explicit, disabled or forced=k where k is the number of shards to enforce&gt;` default: "explicit"
:   Specify strategy for test sharding:

    * `explicit` to only use sharding if the `shard_count` `BUILD` attribute is
      present.
    * `disabled` to never use test sharding.

    common --allowed_strategies_by_exec_platform=@platforms//host:host=local,sandboxed,worker
    common --allowed_strategies_by_exec_platform=//:linux_amd64=remote
    ```

    With the above options;

    * Actions configured for the host platform will be given `remote,sandboxed,worker`.
    * Actions configured for the `//:linux_amd64` platform will be given `remote`.
    * Actions configured for the `//:linux_amd64` platform with mnemonic `Genrule` will be

`--dynamic_local_strategy=<a '[name=]value1[,..,valueN]' assignment&gt;` multiple uses are accumulated
:   The local strategies, in order, to use for the given mnemonic - the first applicable strategy is used. For example, `worker,sandboxed` runs actions that support persistent workers using the worker strategy, and all others using the sandboxed strategy. If no mnemonic is given, the list of strategies is used as the fallback for all mnemonics. The default fallback list is `worker,sandboxed`, or`worker,sandboxed,standalone` if `experimental_local_lockfree_output` is set. Takes [mnemonic=]local\_strategy[,local\_strategy,...]

`--experimental_docker_image=<a string&gt;` default: ""
:   Specify a Docker image name (e.g. "ubuntu:latest") that should be used to execute a sandboxed action when using the docker strategy and the action itself doesn't already have a container-image attribute in its remote\_execution\_properties in the platform description. The value of this flag is passed verbatim to 'docker run', so it supports the same syntax and mechanisms as Docker itself.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

`--[no]experimental_docker_use_customized_images` default: "true"
:   If enabled, injects the uid and gid of the current user into the Docker image before using it. This is required if your build / tests depend on the user having a name and home directory inside the container. This is on by default, but you can disable it in case the automatic image customization feature doesn't work in your case or you know that you don't need it.

    [`execution`](#effect_tag_EXECUTION)

`--[no]experimental_dynamic_exclude_tools` default: "true"

`--experimental_dynamic_local_load_factor=<a double&gt;` default: "0"
:   Controls how much load from dynamic execution to put on the local machine. This flag adjusts how many actions in dynamic execution we will schedule concurrently. It is based on the number of CPUs Blaze thinks is available, which can be controlled with the --local\_resources=cpu= flag.
    If this flag is 0, all actions are scheduled locally immediately. If &gt; 0, the amount of actions scheduled locally is limited by the number of CPUs available. If &lt; 1, the load factor is used to reduce the number of locally scheduled actions when the number of actions waiting to schedule is high. This lessens the load on the local machine in the clean build case, where the local machine does not contribute much.

`--[no]experimental_inmemory_sandbox_stashes` default: "false"
:   If set to true, the contents of stashed sandboxes for reuse\_sandbox\_directories will be tracked in memory. This reduces the amount of I/O needed during reuse. Depending on the build this flag may improve wall time. Depending on the build as well this flag may use a significant amount of additional memory.

:   If 0, sandboxes are deleted as soon as actions finish, blocking action completion. If greater than 0, sandboxes are deleted asynchronously in the background without blocking action completion. Asynchronous deletion uses a single thread while a command is running, but ramps up to as many threads as the value of this flag once the server becomes idle. Set to `auto` to use as many threads as the number of CPUs. A server shutdown blocks on any pending asynchronous deletions.

`--strategy_regexp=<a '&lt;RegexFilter&gt;=value[,value]' assignment&gt;` multiple uses are accumulated
:   Override which spawn strategy should be used to execute spawn actions that have descriptions matching a certain regex\_filter. See --per\_file\_copt for details onregex\_filter matching. The last regex\_filter that matches the description is used. This option overrides other flags for specifying strategy. Example: --strategy\_regexp=//foo.*.cc,-//foo/bar=local means to run actions using local strategy if their descriptions match //foo.*.cc but not //foo/bar. Example: --strategy\_regexp='Compiling.\*/bar=local --strategy\_regexp=Compiling=sandboxed will run 'Compiling //foo/bar/baz' with the 'local' strategy, but reversing the order would run it with 'sandboxed'.

Options that control the output of the command:

`--[no]build` default: "true"
:   Execute the build; this is the usual behaviour.
    Specifying `--nobuild` causes the build to stop before executing the build
    actions, returning zero if the package loading and analysis phases completed
    successfully; this mode is useful for testing those phases.

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--aspects=&lt;comma-separated list of options&gt;` multiple uses are accumulated
:   Comma-separated list of aspects to be applied to top-level targets. In the list, if
    aspect `some_aspect` specifies required aspect providers via
    `required_aspect_providers`, `some_aspect` will run after
    every aspect that was mentioned before it in the aspects list whose advertised
    providers satisfy `some_aspect` required aspect providers. Moreover,
    `some_aspect` will run after all its required aspects specified by
    `requires` attribute.
    `some_aspect` will then have access to the values of those aspects'
    providers.

`--[no]experimental_convenience_symlinks` default: "normal"
:   This flag controls how the convenience symlinks (the symlinks that appear in the
    workspace after the build) will be managed. Possible values:

    * `normal` (default): Each kind of convenience symlink will be created or deleted,
      as determined by the build.
    * `clean`: All symlinks will be unconditionally deleted.
    * `ignore`: Symlinks will not be created or cleaned up.
    * `log_only`: Generate log messages as if `normal` were passed, but don't actually
      perform any filesystem operations (useful for tools).

    Note that only symlinks whose names are generated by the current value of
    `--symlink_prefix` can be affected; if the prefix changes, any pre-existing

Options that govern the behavior of the test environment or test runner:

`--[no]check_tests_up_to_date` default: "false"
:   Don't run tests, just check if they are up-to-date. If all tests results are up-to-date, the testing completes successfully. If any test needs to be built or executed, an error is reported and the testing fails. This option implies --check\_up\_to\_date behavior.

`--flaky_test_attempts=<a positive integer, the string "default", or test_regex@attempts. This flag may be passed more than once&gt;` multiple uses are accumulated
:   Each test will be retried up to the specified number of times in case of any test failure. Tests that required more than one attempt to pass are marked as 'FLAKY' in the test summary. Normally the value specified is just an integer or the string 'default'. If an integer, then all tests will be run up to N times. If 'default', then only a single test attempt will be made for regular tests and three for tests marked explicitly as flaky by their rule (flaky=1 attribute). Alternate syntax: regex\_filter@flaky\_test\_attempts. Where flaky\_test\_attempts is as above and regex\_filter stands for a list of include and exclude regular expression patterns (Also see --runs\_per\_test). Example: --flaky\_test\_attempts=//foo/.*,-//foo/bar/.*@3 deflakes all tests in //foo/ except those under foo/bar three times. This option can be passed multiple times. The most recently passed argument that matches takes precedence. If nothing matches, behavior is as if 'default' above.

Options that trigger optimizations of the build time:

`--cache_computed_file_digests=<a long integer&gt;` default: "50000"
:   If greater than 0, configures Bazel to cache file digests in memory based on their metadata instead of recomputing the digests from disk every time they are needed. Setting this to 0 ensures correctness because not all file changes can be noted from file metadata. When not 0, the number indicates the size of the cache as the number of file digests to be cached.

`--experimental_active_directories=&lt;comma-separated list of options&gt;` default: ""
:   Active directories for Skyfocus and remote analysis caching. Specify as comma-separated workspace root-relative paths. This is a stateful flag. Defining one persists it for subsequent invocations, until it is redefined with a new set.

:   Set the number of resources available to Bazel. Takes in an assignment to a float or HOST\_RAM/HOST\_CPUS, optionally followed by [-|*]&lt;float&gt; (eg. memory=HOST\_RAM*.5 to use half the available RAM). Can be used multiple times to specify multiple types of resources. Bazel will limit concurrently running actions based on the available resources and the resources required. Tests can declare the amount of resources they need by using a tag of the "resources:&lt;resource name&gt;:&lt;amount&gt;" format.

`--[no]sandbox_debug` default: "false"
:   Enables debugging features for the sandboxing feature. This includes two things: first, the sandbox root contents are left untouched after a build; and second, prints extra debugging information on execution. This can help developers of Bazel or Starlark rules with debugging failures due to missing input files, etc.

    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--show_result=&lt;an integer&gt;` default: "1"
:   Show the results of the build. For each target, state whether or not it was brought
    up-to-date, and if so, a list of output files that were built. The printed files
    are convenient strings for copy+pasting to the shell, to execute them.

    This option requires an integer argument, which is the threshold number of targets
    above which result information is not printed. Thus zero causes suppression of
    the message and `MAX_INT` causes printing of the result to occur always. The
    default is one.

    If nothing was built for a target its results may be omitted to keep the output
    under the threshold.

Options specifying or altering a generic input to a Bazel command that does not fall into other categories.:

`--aspects_parameters=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specifies the values of the command-line aspects parameters. Each parameter value is
    specified via `&lt;param_name&gt;=&lt;param_value&gt;`, for example `my_param=my_val` where
    `my_param` is a parameter of some aspect in `--aspects` list or required by an

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

Remote caching and execution options:

`--experimental_circuit_breaker_strategy=&lt;failure&gt;` default: see description
:   Specifies the strategy for the circuit breaker to use. Available strategies are "failure". On invalid value for the option the behavior same as the option is not set.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

`--experimental_remote_cache_compression_threshold=&lt;an integer&gt;` default: "100"
:   The minimum blob size required to compress/decompress with zstd. Ineffectual unless --remote\_cache\_compression is set.

`--experimental_remote_cache_eviction_retries=&lt;an integer&gt;` default: "5"
:   The maximum number of attempts to retry if the build encountered a transient remote cache error that would otherwise fail the build. Applies for example when artifacts are evicted from the remote cache, or in certain cache failure conditions. A new invocation id will be generated for each attempt.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

`--[no]experimental_remote_cache_lease_extension` default: "false"
:   If set to true, Bazel will extend the lease for outputs of remote actions during the build by sending `FindMissingBlobs` calls periodically to remote cache. The frequency is based on the value of `--experimental_remote_cache_ttl`.

`--experimental_remote_cache_ttl=&lt;An immutable length of time.&gt;` default: "3h"
:   The guaranteed minimal TTL of blobs in the remote cache after their digests are recently referenced e.g. by an ActionResult or FindMissingBlobs. Bazel does several optimizations based on the blobs' TTL e.g. doesn't repeatedly call GetActionResult in an incremental build. The value should be set slightly less than the real TTL since there is a gap between when the server returns the digests and when Bazel receives them.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

`--experimental_remote_capture_corrupted_outputs=<a path&gt;` default: see description
:   A path to a directory where the corrupted outputs will be captured to.

`--[no]experimental_remote_discard_merkle_trees` default: "true"
:   If set to true, discard in-memory copies of the input root's Merkle tree and associated input mappings during calls to GetActionResult() and Execute(). This reduces memory usage significantly, but does require Bazel to recompute them upon remote cache misses and retries.

`--experimental_remote_downloader=<a string&gt;` default: see description
:   A Remote Asset API endpoint URI, to be used as a remote download proxy. The supported schemas are grpc, grpcs (grpc with TLS enabled) and unix (local UNIX sockets). If no schema is provided Bazel will default to grpcs. See: https://github.com/bazelbuild/remote-apis/blob/master/build/bazel/remote/asset/v1/remote\_asset.proto

`--[no]experimental_remote_downloader_local_fallback` default: "false"
:   Whether to fall back to the local downloader if remote downloader fails.

`--[no]experimental_remote_downloader_propagate_credentials` default: "false"
:   Whether to propagate credentials from netrc and credential helper to the remote downloader server. The server implementation needs to support the new `http_header_url:&lt;url-index&gt;:&lt;header-key&gt;` qualifier where the `&lt;url-index&gt;` is a 0-based position of the URL inside the FetchBlobRequest's `uris` field. The URL-specific headers should take precedence over the global headers.

`--experimental_remote_failure_rate_threshold=&lt;an integer in 0-100 range&gt;` default: "10"
:   Sets the allowed number of failure rate in percentage for a specific time window after which it stops calling to the remote cache/executor. By default the value is 10. Setting this to 0 means no limitation.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

`--experimental_remote_failure_window_interval=&lt;An immutable length of time.&gt;` default: "60s"
:   The interval in which the failure rate of the remote requests are computed. On zero or negative value the failure duration is computed the whole duration of the execution.Following units can be used: Days (d), hours (h), minutes (m), seconds (s), and milliseconds (ms). If the unit is omitted, the value is interpreted as seconds.

    [`execution`](#effect_tag_EXECUTION)

`--[no]experimental_remote_mark_tool_inputs` default: "false"
:   If set to true, Bazel will mark inputs as tool inputs for the remote executor. This can be used to implement remote persistent workers.

`--experimental_remote_output_service=<a string&gt;` default: see description
:   HOST or HOST:PORT of a remote output service endpoint. The supported schemas are grpc, grpcs (grpc with TLS enabled) and unix (local UNIX sockets). If no schema is provided Bazel will default to grpcs. Specify grpc:// or unix: schema to disable TLS.

`--experimental_remote_output_service_output_path_prefix=<a string&gt;` default: ""
:   The path under which the contents of output directories managed by the --experimental\_remote\_output\_service are placed. The actual output directory used by a build will be a descendant of this path and determined by the output service.

`--[no]experimental_remote_require_cached` default: "false"
:   If set to true, enforce that all actions that can run remotely are cached, or else fail the build. This is useful to troubleshoot non-determinism issues as it allows checking whether actions that should be cached are actually cached without spuriously injecting new results into the cache.

`--experimental_remote_scrubbing_config=&lt;Converts to a Scrubber&gt;` default: see description
:   Enables remote cache key scrubbing with the supplied configuration file, which must be a protocol buffer in text format (see src/main/protobuf/remote\_scrubbing.proto).

    This feature is intended to facilitate sharing a remote/disk cache between actions executing on different platforms but targeting the same platform. It should be used with extreme care, as improper settings may cause accidental sharing of cache entries and result in incorrect builds.

    Scrubbing does not affect how an action is executed, only how its remote/disk cache key is computed for the purpose of retrieving or storing an action result. Scrubbed actions are incompatible with remote execution, and will always be executed locally instead.

    Modifying the scrubbing configuration does not invalidate outputs present in the local filesystem or internal caches; a clean build is required to reexecute affected actions.

    In order to successfully use this feature, you likely want to set a custom --host\_platform together with --experimental\_platform\_in\_output\_dir (to normalize output prefixes).

`--[no]guard_against_concurrent_changes` default: "lite"
:   Set this to 'full' to enable checking the ctime of all input files of an action before uploading it to a remote cache. There may be cases where the Linux kernel delays writing of files, which could cause false positives. The default is 'lite', which only checks source files in the main repository. Setting this to 'off' disables all checks. This is not recommended, as the cache may be polluted when a source file is changed while an action that takes it as an input is executing.

    [`execution`](#effect_tag_EXECUTION)

`--[no]incompatible_remote_local_fallback_for_remote_cache` default: "false"
:   Whether --remote\_local\_fallback applies to --remote\_cache.

`--[no]remote_accept_cached` default: "true"
:   Whether to accept remotely cached action results.

`--remote_build_event_upload=&lt;all or minimal&gt;` default: "minimal"
:   If set to 'all', all local outputs referenced by BEP are uploaded to remote cache.
    If set to 'minimal', local outputs referenced by BEP are not uploaded to the remote cache, except for files that are important to the consumers of BEP (e.g. test logs and timing profile). bytestream:// scheme is always used for the uri of files even if they are missing from remote cache.
    Default to 'minimal'.

`--remote_bytestream_uri_prefix=<a string&gt;` default: see description
:   The hostname and instance name to be used in bytestream:// URIs that are written into build event streams. This option can be set when builds are performed using a proxy, which causes the values of --remote\_executor and --remote\_instance\_name to no longer correspond to the canonical name of the remote execution service. When not set, it will default to "$&#123;hostname&#125;/$&#123;instance\_name&#125;".

`--remote_cache=<a string&gt;` default: see description
:   A URI of a caching endpoint. The supported schemas are http, https, grpc, grpcs (grpc with TLS enabled) and unix (local UNIX sockets). If no schema is provided Bazel will default to grpcs. Specify grpc://, http:// or unix: schema to disable TLS. See https://bazel.build/remote/caching

`--[no]remote_cache_async` default: "true"
:   If true, uploading of action results to a disk or remote cache will happen in the background instead of blocking the completion of an action. Some actions are incompatible with background uploads, and may still block even when this flag is set.

`--[no]remote_cache_compression` default: "false"
:   If enabled, compress/decompress cache blobs with zstd when their size is at least --experimental\_remote\_cache\_compression\_threshold.

`--remote_cache_header=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specify a header that will be included in cache requests: --remote\_cache\_header=Name=Value. Multiple headers can be passed by specifying the flag multiple times. Multiple values for the same name will be converted to a comma-separated list.

`--remote_default_exec_properties=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Set the default exec properties to be used as the remote execution platform if an execution platform does not already set exec\_properties.

`--remote_exec_header=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specify a header that will be included in execution requests: --remote\_exec\_header=Name=Value. Multiple headers can be passed by specifying the flag multiple times. Multiple values for the same name will be converted to a comma-separated list.

`--remote_execution_priority=&lt;an integer&gt;` default: "0"
:   The relative priority of actions to be executed remotely. The semantics of the particular priority values are server-dependent.

`--remote_executor=<a string&gt;` default: see description
:   HOST or HOST:PORT of a remote execution endpoint. The supported schemas are grpc, grpcs (grpc with TLS enabled) and unix (local UNIX sockets). If no schema is provided Bazel will default to grpcs. Specify grpc:// or unix: schema to disable TLS.

`--remote_grpc_log=<a path&gt;` default: see description
:   If specified, a path to a file to log gRPC call related details. This log consists of a sequence of serialized com.google.devtools.build.lib.remote.logging.RemoteExecutionLog.LogEntry protobufs with each message prefixed by a varint denoting the size of the following serialized protobuf message, as performed by the method LogEntry.writeDelimitedTo(OutputStream).

`--remote_header=<a 'name=value' assignment&gt;` multiple uses are accumulated
:   Specify a header that will be included in requests: --remote\_header=Name=Value. Multiple headers can be passed by specifying the flag multiple times. Multiple values for the same name will be converted to a comma-separated list.

`--remote_instance_name=<a string&gt;` default: ""
:   Value to pass as instance\_name in the remote execution API.

`--[no]remote_local_fallback` default: "false"
:   Whether to fall back to standalone local execution strategy if remote execution fails.

`--remote_local_fallback_strategy=<a string&gt;` default: "local"
:   Deprecated. See https://github.com/bazelbuild/bazel/issues/7480 for details.

`--remote_max_concurrency_per_connection=&lt;an integer&gt;` default: "100"
:   Limit the max number of concurrent requests per gRPC connection. By default the value is 100.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--remote_max_connections=&lt;an integer&gt;` default: "100"
:   Limit the max number of concurrent connections to remote cache/executor. By default the value is 100. Setting this to 0 means no limitation.
    For HTTP remote cache, one TCP connection could handle one request at one time, so Bazel could make up to --remote\_max\_connections concurrent requests.
    For gRPC remote cache/executor, one gRPC channel could usually handle 100+ concurrent requests (controlled by --remote\_max\_concurrency\_per\_connection), so Bazel could make around `--remote_max_connections * 100` concurrent requests.

`--remote_proxy=<a string&gt;` default: see description
:   Connect to the remote cache through a proxy. Currently this flag can only be used to configure a Unix domain socket (unix:/path/to/socket).

`--remote_result_cache_priority=&lt;an integer&gt;` default: "0"
:   The relative priority of remote actions to be stored in remote cache. The semantics of the particular priority values are server-dependent.

`--remote_retries=&lt;an integer&gt;` default: "5"
:   The maximum number of attempts to retry a transient error. If set to 0, retries are disabled.

`--remote_retry_max_delay=&lt;An immutable length of time.&gt;` default: "5s"
:   The maximum backoff delay between remote retry attempts. Following units can be used: Days (d), hours (h), minutes (m), seconds (s), and milliseconds (ms). If the unit is omitted, the value is interpreted as seconds.

`--remote_timeout=&lt;An immutable length of time.&gt;` default: "60s"
:   The maximum amount of time to wait for remote execution and cache calls. For the REST cache, this is both the connect and the read timeout. Following units can be used: Days (d), hours (h), minutes (m), seconds (s), and milliseconds (ms). If the unit is omitted, the value is interpreted as seconds.

`--[no]remote_upload_local_results` default: "true"
:   Whether to upload locally executed action results to the remote cache if the remote cache supports it and the user is authorized to do so.

`--[no]remote_verify_downloads` default: "true"
:   If set to true, Bazel will compute the hash sum of all remote downloads and discard the remotely cached values if they don't match the expected value.

Miscellaneous options, not otherwise categorized.:

`--[no]allow_analysis_cache_discard` default: "true"
:   If discarding the analysis cache due to a change in the build system, setting this
    option to false will cause bazel to exit, rather than continuing with the build.
    This option has no effect when `--discard_analysis_cache` is also set.

Allowed values are 'none' (filter nothing / show everything), 'all' (filter everything / show nothing), 'packages' (include output from rules in packages mentioned on the Blaze command line), and 'subpackages' (like 'packages', but also include subpackages). For the 'packages' and 'subpackages' values //java/foo and //javatests/foo are treated as one package)'.

`--[no]build_manual_tests` default: "false"
:   Forces test targets tagged 'manual' to be built. 'manual' tests are excluded from processing. This option forces them to be built (but not executed).

`--build_tag_filters=&lt;comma-separated list of options&gt;` default: ""
:   Specifies a comma-separated list of tags. Each tag can be optionally preceded with '-' to specify excluded tags. Only those targets will be built that contain at least one included tag and do not contain any excluded tags. This option does not affect the set of tests executed with the 'test' command; those are be governed by the test filtering options, for example '--test\_tag\_filters'

`--[no]build_tests_only` default: "false"
:   If specified, only \*\_test and test\_suite rules will be built and other targets specified on the command line will be ignored. By default everything that was requested will be built.

`--combined_report=&lt;none or lcov&gt;` default: "lcov"
:   Specifies desired cumulative coverage report type. At this point only LCOV is supported.

`--[no]compile_one_dependency` default: "false"
:   Compile a single dependency of the argument files. This is useful for syntax checking source files in IDEs, for example, by rebuilding a single target that depends on the source file to detect errors as early as possible in the edit/build/test cycle. This argument affects the way all non-flag arguments are interpreted; instead of being targets to build they are source filenames. For each source filename an arbitrary target that depends on it will be built.

`--deleted_packages=&lt;comma-separated list of package names&gt;` multiple uses are accumulated
:   A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path.
    Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package\_path entry. Specifying --deleted\_packages x/y avoids this problem.

`--[no]discard_analysis_cache` default: "false"
:   Discard the analysis cache immediately after the analysis phase completes. Reduces memory usage by ~10%, but makes further incremental builds slower.

`--disk_cache=<a path&gt;` default: see description
:   A path to a directory where Bazel can read and write actions and action outputs. If the directory does not exist, it will be created.

`--embed_label=<a one-line string&gt;` default: ""
:   Embed source control revision or release label in binary

`--execution_log_binary_file=<a path&gt;` default: see description
:   Log the executed spawns into this file as length-delimited SpawnExec protos, according to src/main/protobuf/spawn.proto. Prefer --execution\_log\_compact\_file, which is significantly smaller and cheaper to produce. Related flags: --execution\_log\_compact\_file (compact format; mutually exclusive), --execution\_log\_json\_file (text JSON format; mutually exclusive), --execution\_log\_sort (whether to sort the execution log), --subcommands (for displaying subcommands in terminal output).

`--execution_log_compact_file=<a path&gt;` default: see description
:   Log the executed spawns into this file as length-delimited ExecLogEntry protos, according to src/main/protobuf/spawn.proto. The entire file is zstd compressed. Related flags: --execution\_log\_binary\_file (binary protobuf format; mutually exclusive), --execution\_log\_json\_file (text JSON format; mutually exclusive), --subcommands (for displaying subcommands in terminal output).

`--execution_log_json_file=<a path&gt;` default: see description
:   Log the executed spawns into this file as newline-delimited JSON representations of SpawnExec protos, according to src/main/protobuf/spawn.proto. Prefer --execution\_log\_compact\_file, which is significantly smaller and cheaper to produce. Related flags: --execution\_log\_compact\_file (compact format; mutually exclusive), --execution\_log\_binary\_file (binary protobuf format; mutually exclusive), --execution\_log\_sort (whether to sort the execution log), --subcommands (for displaying subcommands in terminal output).

`--[no]execution_log_sort` default: "true"
:   Whether to sort the execution log, making it easier to compare logs across invocations. Set to false to avoid potentially significant CPU and memory usage at the end of the invocation, at the cost of producing the log in nondeterministic execution order. Only applies to the binary and JSON formats; the compact format is never sorted.

`--[no]expand_test_suites` default: "true"
:   Expand test\_suite targets into their constituent tests before analysis. When this flag is turned on (the default), negative target patterns will apply to the tests belonging to the test suite, otherwise they will not. Turning off this flag is useful when top-level aspects are applied at command line: then they can analyze test\_suite targets.

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS)

`--experimental_disk_cache_gc_idle_delay=&lt;An immutable length of time.&gt;` default: "5m"
:   How long the server must remain idle before a garbage collection of the disk cache occurs. To specify the garbage collection policy, set --experimental\_disk\_cache\_gc\_max\_size and/or --experimental\_disk\_cache\_gc\_max\_age.

`--experimental_disk_cache_gc_max_age=&lt;An immutable length of time.&gt;` default: "0"
:   If set to a positive value, the disk cache will be periodically garbage collected to remove entries older than this age. If set in conjunction with --experimental\_disk\_cache\_gc\_max\_size, both criteria are applied. Garbage collection occurrs in the background once the server has become idle, as determined by the --experimental\_disk\_cache\_gc\_idle\_delay flag.

`--experimental_disk_cache_gc_max_size=<a size in bytes, optionally followed by a K, M, G or T multiplier&gt;` default: "0"
:   If set to a positive value, the disk cache will be periodically garbage collected to stay under this size. If set in conjunction with --experimental\_disk\_cache\_gc\_max\_age, both criteria are applied. Garbage collection occurrs in the background once the server has become idle, as determined by the --experimental\_disk\_cache\_gc\_idle\_delay flag.

`--experimental_extra_action_filter=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths&gt;` default: ""
:   Deprecated in favor of aspects. Filters set of targets to schedule extra\_actions for.

`--[no]experimental_extra_action_top_level_only` default: "false"
:   Deprecated in favor of aspects. Only schedules extra\_actions for top level targets.

`--experimental_spawn_scheduler`
:   Enable dynamic execution by running actions locally and remotely in parallel. Bazel spawns each action locally and remotely and picks the one that completes first. If an action supports workers, the local action will be run in the persistent worker mode. To enable dynamic execution for an individual action mnemonic, use the `--internal_spawn_scheduler` and `--strategy=&lt;mnemonic&gt;=dynamic` flags instead.

    Expands to:

      `--internal_spawn_scheduler`

      `--spawn_strategy=dynamic`

`--[no]fetch` default: "true"
:   Allows the command to fetch external dependencies. If set to false, the command will utilize any cached version of the dependency, and if none exists, the command will result in failure.

`--local_termination_grace_seconds=&lt;an integer&gt;` default: "15"
:   Time to wait between terminating a local process due to timeout and forcefully shutting it down.

`--package_path=&lt;colon-separated list of options&gt;` default: "%workspace%"
:   A colon-separated list of where to look for packages. Elements beginning with '%workspace%' are relative to the enclosing workspace. If omitted or empty, the default is the output of 'bazel info default-package-path'.

`--[no]show_loading_progress` default: "true"
:   If enabled, causes Bazel to print "Loading package:" messages.

`--test_lang_filters=&lt;comma-separated list of options&gt;` default: ""
:   Specifies a comma-separated list of test languages. Each language can be optionally preceded with '-' to specify excluded languages. Only those test targets will be found that are written in the specified languages. The name used for each language should be the same as the language prefix in the \*\_test rule, e.g. one of 'cc', 'java', 'py', etc. This option affects --build\_tests\_only behavior and the test command.

`--test_size_filters=&lt;comma-separated list of values: small, medium, large, or enormous&gt;` default: ""
:   Specifies a comma-separated list of test sizes. Each size can be optionally preceded with '-' to specify excluded sizes. Only those test targets will be found that contain at least one included size and do not contain any excluded sizes. This option affects --build\_tests\_only behavior and the test command.

`--test_tag_filters=&lt;comma-separated list of options&gt;` default: ""
:   Specifies a comma-separated list of test tags. Each tag can be optionally preceded with '-' to specify excluded tags. Only those test targets will be found that contain at least one included tag and do not contain any excluded tags. This option affects --build\_tests\_only behavior and the test command.

`--test_timeout_filters=&lt;comma-separated list of values: short, moderate, long, or eternal&gt;` default: ""
:   Specifies a comma-separated list of test timeouts. Each timeout can be optionally preceded with '-' to specify excluded timeouts. Only those test targets will be found that contain at least one included timeout and do not contain any excluded timeouts. This option affects --build\_tests\_only behavior and the test command.

`--workspace_status_command=&lt;path&gt;` default: ""
:   A command invoked at the beginning of the build to provide status
    information about the workspace in the form of key/value pairs.
    See the User's Manual for the full specification. Also see
    [`tools/buildstamp/get_workspace_status`](https://github.com/bazelbuild/bazel/blob/master/tools/buildstamp/get_workspace_status) for an example.

`--modify_execution_info=&lt;regex=[+-]key,regex=[+-]key,...&gt;` multiple uses are accumulated
:   Add or remove keys from an action's execution info based on action mnemonic.
    Applies only to actions which support execution info. Many common actions
    support execution info, e.g. Genrule, CppCompile, Javac, StarlarkAction,
    TestRunner. When specifying multiple values, order matters because
    many regexes may apply to the same mnemonic.

    Syntax: `regex=[+-]key,regex=[+-]key,...`.

    Examples:

    * `.*=+x,.*=-y,.*=+z` adds `x` and `z` to, and removes `y` from, the execution info for all actions.
    * `Genrule=+requires-x` adds `requires-x` to the execution info for all Genrule actions.
    * `(?!Genrule).*=-requires-x` removes `requires-x` from the execution info for all non-Genrule actions.

    case its value will be read from the Bazel client environment, or by the
    `name=value` pair.
    Previously set variables can be unset via `=name`.
    This option can be used multiple times to specify several variables.
    Used only by the 'bazel test' command.

`--test_timeout=<a single integer or comma-separated list of 4 integers&gt;` default: "-1"
:   Override the default test timeout values for test timeouts (in secs). If a single
    positive integer value is specified it will override all categories. If 4
    comma-separated integers are specified, they will override the timeouts for
    `short`, `moderate`, `long` and `eternal` (in that order). In either form, a value of
    -1 tells blaze to use its default timeouts for that category.

`--[no]zip_undeclared_test_outputs` default: "false"
:   If true, undeclared test outputs will be archived in a zip file.

`--[no]cc_include_scanning` default: "false"
:   Whether to narrow inputs to C/C++ compilation by parsing #include lines from input files. This can improve performance and incrementality by decreasing the size of compilation input trees. However, it can also break builds because the include scanner does not fully implement C preprocessor semantics. In particular, it does not understand dynamic #include directives and ignores preprocessor conditional logic. Use at your own risk. Any issues relating to this flag that are filed will be closed. At Google without this flag your build will most likely fail.

`--[no]experimental_retain_test_configuration_across_testonly` default: "true"
:   When enabled, `--trim_test_configuration` will not trim the test configuration for rules
    marked testonly=1. This is meant to reduce action conflict issues when non-test
    rules depend on `cc_test` rules. No effect if `--trim_test_configuration` is

Options that affect the verbosity, format or location of logging:

`--toolchain_resolution_debug=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths&gt;` default: "-.\*"
:   Print debug information during toolchain resolution. The flag takes a regex, which is checked against toolchain types and specific targets to see which to debug. Multiple regexes may be separated by commas, and then each regex is checked separately. Note: The output of this flag is very complex and will likely only be useful to experts in toolchain resolution.

`--[no]incompatible_default_to_explicit_init_py` default: "false"
:   This flag changes the default behavior so that **init**.py files are no longer automatically created in the runfiles of Python targets. Precisely, when a py\_binary or py\_test target has legacy\_create\_init set to "auto" (the default), it is treated as false if and only if this flag is set.

Miscellaneous options, not otherwise categorized.:

`--[no]cache_test_results` [`-t`] default: "auto"
:   If set to `auto`, Bazel reruns a test if and only if:

    1. Bazel detects changes in the test or its dependencies,
    2. The test is marked as `external`,
    3. Multiple test runs were requested with `--runs_per_test`, or
    4. The test previously failed.
       If set to `yes`, Bazel caches all test results except for tests marked as
       `external`. If set to `no`, Bazel does not cache any test results.

`--[no]experimental_cancel_concurrent_tests` default: "never"
:   If `on_failed` or `on_passed`, then Blaze will cancel concurrently running tests on the first
    successful run with that result. This is only useful in combination with

`--[no]explicit_java_test_deps` default: "false"
:   Explicitly specify a dependency to JUnit or Hamcrest in a java\_test instead of accidentally obtaining from the TestRunner's deps. Only works for bazel right now.

`--host_java_launcher=<a build target label&gt;` default: see description
:   The Java launcher used by tools that are executed during a build.

`--host_javacopt=<a string&gt;` multiple uses are accumulated
:   Additional options to pass to javac when building tools that are executed during a build.

`--host_jvmopt=<a string&gt;` multiple uses are accumulated
:   Additional options to pass to the Java VM when building tools that are executed during the build. These options will get added to the VM startup options of each java\_binary target.

`--[no]incompatible_check_sharding_support` default: "true"
:   If true, Bazel will fail a sharded test if the test runner does not indicate that it
    supports sharding by touching the file at the path in `TEST_SHARD_STATUS_FILE`.
    If false, a test runner that does not support sharding will lead to all tests

`--[no]incompatible_strict_action_env` default: "true"
:   If true, Bazel uses an environment with a static value for PATH and does not
    inherit `LD_LIBRARY_PATH`. Use `--action_env=ENV_VARIABLE` if you want to
    inherit specific environment variables from the client, but note that doing so
    can prevent cross-user caching if a shared cache is used.

    default path depending on the operating system it runs on;

    * Windows: `c:/msys64/usr/bin/bash.exe`
    * FreeBSD: `/usr/local/bin/bash`
    * All others: `/bin/bash`.

    Note that using a shell that is not compatible with `bash` may lead

`--test_arg=<a string&gt;` multiple uses are accumulated
:   Specifies additional options and arguments that should be passed to the test

    If multiple tests are executed, each of them will receive identical arguments.
    Used only by the `bazel test` command.

`--test_filter=<a string&gt;` default: see description
:   Specifies a filter to forward to the test framework. Used to limit the tests run. Note that this does not affect which targets are built.

`--test_result_expiration=&lt;an integer&gt;` default: "-1"
:   This option is deprecated and has no effect.

`--[no]test_runner_fail_fast` default: "false"
:   Forwards fail fast option to the test runner. The test runner should stop execution upon first failure.

`--test_sharding_strategy=&lt;explicit, disabled or forced=k where k is the number of shards to enforce&gt;` default: "explicit"

## Canonicalize-flags Options

Inherits all options from [build](#build).

Options that control the output of the command:

`--[no]canonicalize_policy` default: "false"
:   Output the canonical policy, after expansion and filtering. To keep the output clean, the canonicalized command arguments will NOT be shown when this option is set to true. Note that the command specified by --for\_command affects the filtered policy, and if none is specified, the default command is 'build'.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

This option affects semantics of the Starlark language or the build API accessible to BUILD files, .bzl files, or WORKSPACE files.:

`--[no]incompatible_config_setting_private_default_visibility` default: "false"
:   If incompatible\_enforce\_config\_setting\_visibility=false, this is a noop. Else, if this flag is false, any config\_setting without an explicit visibility attribute is //visibility:public. If this flag is true, config\_setting follows the same visibility logic as all other rules. See https://github.com/bazelbuild/bazel/issues/12933.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--invocation_policy=<a string&gt;` default: ""
:   Applies an invocation policy to the options to be canonicalized.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

Miscellaneous options, not otherwise categorized.:

`--deleted_packages=&lt;comma-separated list of package names&gt;` multiple uses are accumulated
:   A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path.
    Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package\_path entry. Specifying --deleted\_packages x/y avoids this problem.

`--[no]fetch` default: "true"
:   Allows the command to fetch external dependencies. If set to false, the command will utilize any cached version of the dependency, and if none exists, the command will result in failure.

`--package_path=&lt;colon-separated list of options&gt;` default: "%workspace%"
:   A colon-separated list of where to look for packages. Elements beginning with '%workspace%' are relative to the enclosing workspace. If omitted or empty, the default is the output of 'bazel info default-package-path'.

`--[no]show_loading_progress` default: "true"
:   If enabled, causes Bazel to print "Loading package:" messages.

## Clean Options

Inherits all options from [build](#build).

Options that control the output of the command:

`--[no]async` default: "false"
:   If true, output cleaning is asynchronous. When this command completes, it will be safe to execute new commands in the same client, even though the deletion may continue in the background.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--[no]expunge` default: "false"
:   If true, clean removes the entire working tree for this bazel instance, which includes all bazel-created temporary and build output files, and stops the bazel server if it is running.

    Tags:
    [`host_machine_resource_optimizations`](#effect_tag_HOST_MACHINE_RESOURCE_OPTIMIZATIONS)

`--expunge_async`
:   If specified, clean asynchronously removes the entire working tree for this bazel instance, which includes all bazel-created temporary and build output files, and stops the bazel server if it is running. When this command completes, it will be safe to execute new commands in the same client, even though the deletion may continue in the background.

    Expands to:

## Config Options

## Coverage Options

Inherits all options from [test](#test).

## Cquery Options

Inherits all options from [test](#test).

Options relating to query output and semantics:

`--aspect_deps=&lt;off, conservative or precise&gt;` default: "conservative"
:   How to resolve aspect dependencies when the output format is one of &#123;xml,proto,record&#125;. 'off' means no aspect dependencies are resolved, 'conservative' (the default) means all declared aspect dependencies are added regardless of whether they are given the rule class of direct dependencies, 'precise' means that only those aspects are added that are possibly active given the rule class of the direct dependencies. Note that precise mode requires loading other packages to evaluate a single target thus making it slower than the other modes. Also note that even precise mode is not completely precise: the decision whether to compute an aspect is decided in the analysis phase, which is not run during 'bazel query'.

    Tags:
    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

`--[no]consistent_labels` default: "false"
:   If enabled, every query command emits labels as if by the Starlark <code>str</code> function applied to a <code>Label</code> instance. This is useful for tools that need to match the output of different query commands and/or labels emitted by rules. If not enabled, output formatters are free to emit apparent repository names (relative to the main repository) instead to make the output more readable.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]experimental_explicit_aspects` default: "false"
:   aquery, cquery: whether to include aspect-generated actions in the output. query: no-op (aspects are always followed).

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]graph:factored` default: "true"
:   If true, then the graph will be emitted 'factored', i.e. topologically-equivalent nodes will be merged together and their labels concatenated. This option is only applicable to --output=graph.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--graph:node_limit=&lt;an integer&gt;` default: "512"
:   The maximum length of the label string for a graph node in the output. Longer labels will be truncated; -1 means no truncation. This option is only applicable to --output=graph.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

`--[no]implicit_deps` default: "true"
:   If enabled, implicit dependencies will be included in the dependency graph over which the query operates. An implicit dependency is one that is not explicitly specified in the BUILD file but added by bazel. For cquery, this option controls filtering resolved toolchains.

    Tags:
    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

`--[no]include_aspects` default: "true"
:   aquery, cquery: whether to include aspect-generated actions in the output. query: no-op (aspects are always followed).

`--[no]incompatible_package_group_includes_double_slash` default: "true"
:   If enabled, when outputting package\_group's `packages` attribute, the leading `//` will not be omitted.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

`--[no]infer_universe_scope` default: "false"
:   If set and --universe\_scope is unset, then a value of --universe\_scope will be inferred as the list of unique target patterns in the query expression. Note that the --universe\_scope value inferred for a query expression that uses universe-scoped functions (e.g.`allrdeps`) may not be what you want, so you should use this option only if you know what you are doing. See https://bazel.build/reference/query#sky-query for details and examples. If --universe\_scope is set, then this option's value is ignored. Note: this option applies only to `query` (i.e. not `cquery`).

`--[no]tool_deps` default: "true"
:   Query: If disabled, dependencies on 'exec configuration' will not be included in the dependency graph over which the query operates. An 'exec configuration' dependency edge, such as the one from any 'proto\_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same 'target' program.
    Cquery: If disabled, filters out all configured targets which cross an execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the exec configuration, only exec configured targets will be returned. This option will NOT exclude resolved toolchains.

`--universe_scope=&lt;comma-separated list of options&gt;` default: ""
:   A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands.
    For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.

`--modify_execution_info=&lt;regex=[+-]key,regex=[+-]key,...&gt;` multiple uses are accumulated
:   Add or remove keys from an action's execution info based on action mnemonic.
    Applies only to actions which support execution info. Many common actions
    support execution info, e.g. Genrule, CppCompile, Javac, StarlarkAction,
    TestRunner. When specifying multiple values, order matters because
    many regexes may apply to the same mnemonic.

    Syntax: `regex=[+-]key,regex=[+-]key,...`.

    Examples:

    * `.*=+x,.*=-y,.*=+z` adds `x` and `z` to, and removes `y` from, the execution info for all actions.
    * `Genrule=+requires-x` adds `requires-x` to the execution info for all Genrule actions.
    * `(?!Genrule).*=-requires-x` removes `requires-x` from the execution info for all non-Genrule actions.

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--action_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies the set of environment variables available to actions with target

    the value will be taken from the invocation environment, by the `name=value`
    pair which sets the value independent of the invocation environment, or by
    `=name`, which unsets the variable of that name. This option can be used

    just an integer.

    Example: `--runs_per_test=3` will run all tests 3 times.

    Alternate syntax: `regex_filter@runs_per_test`. Where `runs_per_test` stands for
    an integer value and `regex_filter` stands for a list of include and exclude
    regular expression patterns (Also see --instrumentation\_filter).

    Example: `--runs_per_test=//foo/.*,-//foo/bar/.*@3` runs all tests in `//foo/` except
    those under `//foo/bar` three times. This option can be passed multiple times. The most
    recently passed argument that matches takes precedence. If nothing matches,
    the test is only run once.

`--test_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies additional environment variables to be injected into the test runner
    environment. Variables can be either specified by `name`, in which
    case its value will be read from the Bazel client environment, or by the
    `name=value` pair.
    Previously set variables can be unset via `=name`.
    This option can be used multiple times to specify several variables.
    Used only by the 'bazel test' command.

`--test_timeout=<a single integer or comma-separated list of 4 integers&gt;` default: "-1"
:   Override the default test timeout values for test timeouts (in secs). If a single
    positive integer value is specified it will override all categories. If 4
    comma-separated integers are specified, they will override the timeouts for
    `short`, `moderate`, `long` and `eternal` (in that order). In either form, a value of
    -1 tells blaze to use its default timeouts for that category.

`--[no]zip_undeclared_test_outputs` default: "false"
:   If true, undeclared test outputs will be archived in a zip file.

`--[no]cc_include_scanning` default: "false"
:   Whether to narrow inputs to C/C++ compilation by parsing #include lines from input files. This can improve performance and incrementality by decreasing the size of compilation input trees. However, it can also break builds because the include scanner does not fully implement C preprocessor semantics. In particular, it does not understand dynamic #include directives and ignores preprocessor conditional logic. Use at your own risk. Any issues relating to this flag that are filed will be closed. At Google without this flag your build will most likely fail.

`--[no]experimental_retain_test_configuration_across_testonly` default: "true"
:   When enabled, `--trim_test_configuration` will not trim the test configuration for rules
    marked testonly=1. This is meant to reduce action conflict issues when non-test
    rules depend on `cc_test` rules. No effect if `--trim_test_configuration` is

Options that affect the verbosity, format or location of logging:

`--toolchain_resolution_debug=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths&gt;` default: "-.\*"
:   Print debug information during toolchain resolution. The flag takes a regex, which is checked against toolchain types and specific targets to see which to debug. Multiple regexes may be separated by commas, and then each regex is checked separately. Note: The output of this flag is very complex and will likely only be useful to experts in toolchain resolution.

`--[no]incompatible_default_to_explicit_init_py` default: "false"
:   This flag changes the default behavior so that **init**.py files are no longer automatically created in the runfiles of Python targets. Precisely, when a py\_binary or py\_test target has legacy\_create\_init set to "auto" (the default), it is treated as false if and only if this flag is set.

Miscellaneous options, not otherwise categorized.:

`--[no]cache_test_results` [`-t`] default: "auto"
:   If set to `auto`, Bazel reruns a test if and only if:

    1. Bazel detects changes in the test or its dependencies,
    2. The test is marked as `external`,
    3. Multiple test runs were requested with `--runs_per_test`, or
    4. The test previously failed.
       If set to `yes`, Bazel caches all test results except for tests marked as
       `external`. If set to `no`, Bazel does not cache any test results.

`--[no]experimental_cancel_concurrent_tests` default: "never"
:   If `on_failed` or `on_passed`, then Blaze will cancel concurrently running tests on the first
    successful run with that result. This is only useful in combination with

`--[no]explicit_java_test_deps` default: "false"
:   Explicitly specify a dependency to JUnit or Hamcrest in a java\_test instead of accidentally obtaining from the TestRunner's deps. Only works for bazel right now.

`--host_java_launcher=<a build target label&gt;` default: see description
:   The Java launcher used by tools that are executed during a build.

`--host_javacopt=<a string&gt;` multiple uses are accumulated
:   Additional options to pass to javac when building tools that are executed during a build.

`--host_jvmopt=<a string&gt;` multiple uses are accumulated
:   Additional options to pass to the Java VM when building tools that are executed during the build. These options will get added to the VM startup options of each java\_binary target.

`--[no]incompatible_check_sharding_support` default: "true"
:   If true, Bazel will fail a sharded test if the test runner does not indicate that it
    supports sharding by touching the file at the path in `TEST_SHARD_STATUS_FILE`.
    If false, a test runner that does not support sharding will lead to all tests

`--[no]incompatible_strict_action_env` default: "true"
:   If true, Bazel uses an environment with a static value for PATH and does not
    inherit `LD_LIBRARY_PATH`. Use `--action_env=ENV_VARIABLE` if you want to
    inherit specific environment variables from the client, but note that doing so
    can prevent cross-user caching if a shared cache is used.

:   Absolute path to the shell executable for Bazel to use. If this is unset, but the
    `BAZEL_SH` environment variable is set on the first Bazel invocation (that starts
    up a Bazel server), Bazel uses that. If neither is set, Bazel uses a hard-coded
    default path depending on the operating system it runs on;

    * Windows: `c:/msys64/usr/bin/bash.exe`
    * FreeBSD: `/usr/local/bin/bash`

:   Specifies a filter to forward to the test framework. Used to limit the tests run. Note that this does not affect which targets are built.

`--test_result_expiration=&lt;an integer&gt;` default: "-1"
:   This option is deprecated and has no effect.

`--[no]test_runner_fail_fast` default: "false"

Options relating to Bzlmod output and semantics:

`--[no]configure` default: "false"
:   Only fetches repositories marked as `configure` for system-configuration purpose. Only
    works when `--enable_bzlmod` is on.

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

    `@@canonical_repo_name`. Only works when `--enable_bzlmod` is on.

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

Miscellaneous options, not otherwise categorized.:

`--deleted_packages=&lt;comma-separated list of package names&gt;` multiple uses are accumulated
:   A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path.
    Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package\_path entry. Specifying --deleted\_packages x/y avoids this problem.

`--[no]fetch` default: "true"
:   Allows the command to fetch external dependencies. If set to false, the command will utilize any cached version of the dependency, and if none exists, the command will result in failure.

`--package_path=&lt;colon-separated list of options&gt;` default: "%workspace%"
:   A colon-separated list of where to look for packages. Elements beginning with '%workspace%' are relative to the enclosing workspace. If omitted or empty, the default is the output of 'bazel info default-package-path'.

`--[no]show_loading_progress` default: "true"
:   If enabled, causes Bazel to print "Loading package:" messages.

Options that control build execution:

`--[no]experimental_persistent_aar_extractor` default: "false"

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`execution`](#effect_tag_EXECUTION), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]experimental_split_coverage_postprocessing` default: "false"
:   If true, then Bazel will run coverage postprocessing for test in a new spawn.

    Tags:
    [`execution`](#effect_tag_EXECUTION), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]experimental_strict_fileset_output` default: "false"

`--[no]incompatible_modify_execution_info_additive` default: "true"
:   When enabled, passing multiple `--modify_execution_info` flags is additive.
    When disabled, only the last flag is taken into account.

    Tags:

`--modify_execution_info=&lt;regex=[+-]key,regex=[+-]key,...&gt;` multiple uses are accumulated
:   Add or remove keys from an action's execution info based on action mnemonic.
    Applies only to actions which support execution info. Many common actions
    support execution info, e.g. Genrule, CppCompile, Javac, StarlarkAction,
    TestRunner. When specifying multiple values, order matters because
    many regexes may apply to the same mnemonic.

    Syntax: `regex=[+-]key,regex=[+-]key,...`.

    Examples:

`--default_test_resources=<a resource name followed by equal and 1 float or 4 float, e.g memory=10,30,60,100&gt;` multiple uses are accumulated
:   Override the default resources amount for tests. The expected format is
    `&#123;resource&#125;=&#123;value&#125;`. If a single positive number is specified as `&#123;value&#125;`
    it will override the default resources for all test sizes. If 4
    comma-separated numbers are specified, they will override the resource
    amount for respectively the `small`, `medium`, `large`, `enormous` test sizes.
    Values can also be `HOST_RAM`/`HOST_CPU`, optionally followed
    by `[-|*]&#123;float&#125;` (eg. `memory=HOST_RAM*.1,HOST_RAM*.2,HOST_RAM*.3,HOST_RAM*.4`).
    The default test resources specified by this flag are overridden by explicit
    resources specified in tags.

    [`test_runner`](#effect_tag_TEST_RUNNER)

`--runs_per_test=<a positive integer or test_regex@runs. This flag may be passed more than once&gt;` multiple uses are accumulated
:   Specifies number of times to run each test. If any of those attempts fail for any
    reason, the whole test is considered failed. Normally the value specified is
    just an integer.

    Example: `--runs_per_test=3` will run all tests 3 times.

    Alternate syntax: `regex_filter@runs_per_test`. Where `runs_per_test` stands for
    an integer value and `regex_filter` stands for a list of include and exclude
    regular expression patterns (Also see --instrumentation\_filter).

    Example: `--runs_per_test=//foo/.*,-//foo/bar/.*@3` runs all tests in `//foo/` except
    those under `//foo/bar` three times. This option can be passed multiple times. The most
    recently passed argument that matches takes precedence. If nothing matches,
    the test is only run once.

`--test_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies additional environment variables to be injected into the test runner
    environment. Variables can be either specified by `name`, in which
    case its value will be read from the Bazel client environment, or by the
    `name=value` pair.
    Previously set variables can be unset via `=name`.
    This option can be used multiple times to specify several variables.
    Used only by the 'bazel test' command.

`--test_timeout=<a single integer or comma-separated list of 4 integers&gt;` default: "-1"
:   Override the default test timeout values for test timeouts (in secs). If a single
    positive integer value is specified it will override all categories. If 4
    comma-separated integers are specified, they will override the timeouts for
    `short`, `moderate`, `long` and `eternal` (in that order). In either form, a value of
    -1 tells blaze to use its default timeouts for that category.

`--[no]zip_undeclared_test_outputs` default: "false"

`--[no]cc_include_scanning` default: "false"
:   Whether to narrow inputs to C/C++ compilation by parsing #include lines from input files. This can improve performance and incrementality by decreasing the size of compilation input trees. However, it can also break builds because the include scanner does not fully implement C preprocessor semantics. In particular, it does not understand dynamic #include directives and ignores preprocessor conditional logic. Use at your own risk. Any issues relating to this flag that are filed will be closed.

Options that affect the verbosity, format or location of logging:

`--toolchain_resolution_debug=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths&gt;` default: "-.\*"
:   Print debug information during toolchain resolution. The flag takes a regex, which is checked against toolchain types and specific targets to see which to debug. Multiple regexes may be separated by commas, and then each regex is checked separately. Note: The output of this flag is very complex and will likely only be useful to experts in toolchain resolution.

Miscellaneous options, not otherwise categorized.:

`--[no]cache_test_results` [`-t`] default: "auto"
:   If set to `auto`, Bazel reruns a test if and only if:

    1. Bazel detects changes in the test or its dependencies,
    2. The test is marked as `external`,
    3. Multiple test runs were requested with `--runs_per_test`, or
    4. The test previously failed.
       If set to `yes`, Bazel caches all test results except for tests marked as
       `external`. If set to `no`, Bazel does not cache any test results.

`--[no]experimental_cancel_concurrent_tests` default: "never"
:   If `on_failed` or `on_passed`, then Blaze will cancel concurrently running tests on the first
    successful run with that result. This is only useful in combination with

`--host_java_launcher=<a build target label&gt;` default: see description
:   The Java launcher used by tools that are executed during a build.

`--host_javacopt=<a string&gt;` multiple uses are accumulated

`--host_jvmopt=<a string&gt;` multiple uses are accumulated
:   Additional options to pass to the Java VM when building tools that are executed during the build. These options will get added to the VM startup options of each java\_binary target.

`--[no]incompatible_check_sharding_support` default: "true"

`--loading_phase_threads=&lt;an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]&lt;float&gt;) eg. "auto", "HOST_CPUS*.5"&gt;` default: "auto"
:   Number of parallel threads to use for the loading/analysis phase.Takes an integer, or a keyword ("auto", "HOST\_CPUS", "HOST\_RAM"), optionally followed by an operation ([-|*]&lt;float&gt;) eg. "auto", "HOST\_CPUS*.5". "auto" sets a reasonable default based on host resources. Must be at least 1.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--modify_execution_info=&lt;regex=[+-]key,regex=[+-]key,...&gt;` multiple uses are accumulated
:   Add or remove keys from an action's execution info based on action mnemonic.
    Applies only to actions which support execution info. Many common actions
    support execution info, e.g. Genrule, CppCompile, Javac, StarlarkAction,
    TestRunner. When specifying multiple values, order matters because
    many regexes may apply to the same mnemonic.

    Syntax: `regex=[+-]key,regex=[+-]key,...`.

    Examples:

    * `.*=+x,.*=-y,.*=+z` adds `x` and `z` to, and removes `y` from, the execution info for all actions.
    * `Genrule=+requires-x` adds `requires-x` to the execution info for all Genrule actions.
    * `(?!Genrule).*=-requires-x` removes `requires-x` from the execution info for all non-Genrule actions.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

Options that configure the toolchain used for action execution:

`--[no]incompatible_bazel_test_exec_run_under` default: "true"
:   If enabled, `bazel test --run_under=//:runner` builds `//:runner` in the exec
    configuration. If disabled, it builds `//:runner` in the target configuration.
    Bazel executes tests on exec machines, so the former is more correct. This
    doesn't affect `bazel run`, which always builds `--run_under=//foo` in the
    target configuration.

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--action_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies the set of environment variables available to actions with target
    configuration. Variables can be either specified by `name`, in which case
    the value will be taken from the invocation environment, by the `name=value`
    pair which sets the value independent of the invocation environment, or by
    `=name`, which unsets the variable of that name. This option can be used
    multiple times; for options given for the same variable, the latest wins,
    options for different variables accumulate.

    Note that unless `--incompatible_repo_env_ignores_action_env` is true, all `name=value`
    pairs will be available to repository rules.

    instead of the CPU. The exact scheme is experimental and subject to change:

    1. First, in the rare case the `--platforms` option does not have exactly one value, a
       hash of the platforms option is used.
    2. Next, if any shortname for the current platform was registered by
       `--experimental_override_name_platform_in_output_dir`, then that shortname is used.
    3. Then, if `--experimental_use_platforms_in_output_dir_legacy_heuristic` is set, use a
       shortname based off the current platform Label.
    4. Finally, a hash of the platform option is used as a last resort.

Options that govern the behavior of the test environment or test runner:

`--[no]allow_analysis_failures` default: "false"

`--[no]include_unused` default: "false"
:   The queries will also take into account and display the unused modules, which are not
    present in the module resolution graph after selection (due to the
    Minimal-Version Selection or override rules). This can have different effects for
    each of the query types i.e. include new paths in the `all_paths` command, or extra

Options specifying or altering a generic input to a Bazel command that does not fall into other categories.:

`--flag_alias=<a 'name=value' flag alias&gt;` multiple uses are accumulated
:   Sets a shorthand name for a Starlark flag. It takes a single key-value pair in the form

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS), [`non_configurable`](#metadata_tag_NON_CONFIGURABLE)

Miscellaneous options, not otherwise categorized.:

`--deleted_packages=&lt;comma-separated list of package names&gt;` multiple uses are accumulated
:   A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path.
    Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package\_path entry. Specifying --deleted\_packages x/y avoids this problem.

`--[no]fetch` default: "true"
:   Allows the command to fetch external dependencies. If set to false, the command will utilize any cached version of the dependency, and if none exists, the command will result in failure.

`--package_path=&lt;colon-separated list of options&gt;` default: "%workspace%"
:   A colon-separated list of where to look for packages. Elements beginning with '%workspace%' are relative to the enclosing workspace. If omitted or empty, the default is the output of 'bazel info default-package-path'.

`--[no]show_loading_progress` default: "true"
:   If enabled, causes Bazel to print "Loading package:" messages.

## Print\_action Options

Inherits all options from [build](#build).

Miscellaneous options, not otherwise categorized.:

`--print_action_mnemonics=<a string&gt;` multiple uses are accumulated

`--loading_phase_threads=&lt;an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]&lt;float&gt;) eg. "auto", "HOST_CPUS*.5"&gt;` default: "auto"
:   Number of parallel threads to use for the loading/analysis phase.Takes an integer, or a keyword ("auto", "HOST\_CPUS", "HOST\_RAM"), optionally followed by an operation ([-|*]&lt;float&gt;) eg. "auto", "HOST\_CPUS*.5". "auto" sets a reasonable default based on host resources. Must be at least 1.

    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

`--modify_execution_info=&lt;regex=[+-]key,regex=[+-]key,...&gt;` multiple uses are accumulated
:   Add or remove keys from an action's execution info based on action mnemonic.
    Applies only to actions which support execution info. Many common actions
    support execution info, e.g. Genrule, CppCompile, Javac, StarlarkAction,
    TestRunner. When specifying multiple values, order matters because
    many regexes may apply to the same mnemonic.

    Syntax: `regex=[+-]key,regex=[+-]key,...`.

    Examples:

    * `.*=+x,.*=-y,.*=+z` adds `x` and `z` to, and removes `y` from, the execution info for all actions.
    * `Genrule=+requires-x` adds `requires-x` to the execution info for all Genrule actions.
    * `(?!Genrule).*=-requires-x` removes `requires-x` from the execution info for all non-Genrule actions.

    Tags:
    [`execution`](#effect_tag_EXECUTION)

Options that configure the toolchain used for action execution:

`--[no]incompatible_bazel_test_exec_run_under` default: "true"
:   If enabled, `bazel test --run_under=//:runner` builds `//:runner` in the exec
    configuration. If disabled, it builds `//:runner` in the target configuration.
    Bazel executes tests on exec machines, so the former is more correct. This
    doesn't affect `bazel run`, which always builds `--run_under=//foo` in the
    target configuration.

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--action_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies the set of environment variables available to actions with target
    configuration. Variables can be either specified by `name`, in which case
    the value will be taken from the invocation environment, by the `name=value`
    pair which sets the value independent of the invocation environment, or by
    `=name`, which unsets the variable of that name. This option can be used
    multiple times; for options given for the same variable, the latest wins,
    options for different variables accumulate.

    Note that unless `--incompatible_repo_env_ignores_action_env` is true, all `name=value`
    pairs will be available to repository rules.

    possible) and will collect coverage information during tests. Only targets that
    match `--instrumentation_filter` will be affected. Usually this option should
    not be specified directly - `bazel coverage` command should be used instead.

    instead of the CPU. The exact scheme is experimental and subject to change:

    1. First, in the rare case the `--platforms` option does not have exactly one value, a
       hash of the platforms option is used.
    2. Next, if any shortname for the current platform was registered by
       `--experimental_override_name_platform_in_output_dir`, then that shortname is used.
    3. Then, if `--experimental_use_platforms_in_output_dir_legacy_heuristic` is set, use a
       shortname based off the current platform Label.
    4. Finally, a hash of the platform option is used as a last resort.

    value will be taken from the invocation environment, by the `name=value` pair
    which sets the value independent of the invocation environment, or by
    `=name`, which unsets the variable of that name. This option can
    be used multiple times; for options given for the same variable, the latest
    wins, options for different variables accumulate.

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

`--[no]instrument_test_targets` default: "false"
:   When coverage is enabled, specifies whether to consider instrumenting test rules.
    When set, test rules included by `--instrumentation_filter` are instrumented.
    Otherwise, test rules are always excluded from coverage instrumentation.

`--instrumentation_filter=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths&gt;` default: "-/javatests[/:],-/test/java[/:]"
:   When coverage is enabled, only rules with names included by the
    specified regex-based filter will be instrumented. Rules prefixed
    with '-' are excluded instead. Note that only non-test rules are
    instrumented unless `--instrument_test_targets` is enabled.

This option affects semantics of the Starlark language or the build API accessible to BUILD files, .bzl files, or WORKSPACE files.:

`--[no]incompatible_config_setting_private_default_visibility` default: "false"
:   If incompatible\_enforce\_config\_setting\_visibility=false, this is a noop. Else, if this flag is false, any config\_setting without an explicit visibility attribute is //visibility:public.

Options that govern the behavior of the test environment or test runner:

`--[no]allow_analysis_failures` default: "false"
:   If true, an analysis failure of a rule target results in the target's propagation
    of an instance of `AnalysisFailureInfo` containing the error description, instead
    of resulting in a build failure.

    a `for_analysis_testing` configuration transition.
    Exceeding this limit will result in a rule error.

    Tags:
    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS)

Options relating to query output and semantics:

`--aspect_deps=&lt;off, conservative or precise&gt;` default: "conservative"
:   How to resolve aspect dependencies when the output format is one of &#123;xml,proto,record&#125;. 'off' means no aspect dependencies are resolved, 'conservative' (the default) means all declared aspect dependencies are added regardless of whether they are given the rule class of direct dependencies, 'precise' means that only those aspects are added that are possibly active given the rule class of the direct dependencies. Note that precise mode requires loading other packages to evaluate a single target thus making it slower than the other modes. Also note that even precise mode is not completely precise: the decision whether to compute an aspect is decided in the analysis phase, which is not run during 'bazel query'.

    Tags:
    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS)

`--[no]consistent_labels` default: "false"
:   If enabled, every query command emits labels as if by the Starlark <code>str</code> function applied to a <code>Label</code> instance. This is useful for tools that need to match the output of different query commands and/or labels emitted by rules. If not enabled, output formatters are free to emit apparent repository names (relative to the main repository) instead to make the output more readable.

`--[no]infer_universe_scope` default: "false"
:   If set and --universe\_scope is unset, then a value of --universe\_scope will be inferred as the list of unique target patterns in the query expression. Note that the --universe\_scope value inferred for a query expression that uses universe-scoped functions (e.g.`allrdeps`) may not be what you want, so you should use this option only if you know what you are doing. See https://bazel.build/reference/query#sky-query for details and examples. If --universe\_scope is set, then this option's value is ignored. Note: this option applies only to `query` (i.e. not `cquery`).

`--[no]nodep_deps` default: "true"
:   If enabled, deps from "nodep" attributes will be included in the dependency graph over which the query operates. A common example of a "nodep" attribute is "visibility". Run and parse the output of `info build-language` to learn about all the "nodep" attributes in the build language.

`--order_output=&lt;no, deps, auto or full&gt;` default: "auto"
:   Output the results unordered (no), dependency-ordered (deps), or fully ordered (full). The default is 'auto', meaning that results are output either dependency-ordered or fully ordered, depending on the output formatter (dependency-ordered for proto, minrank, maxrank, and graph, fully ordered for all others). When output is fully ordered, nodes are printed in a fully deterministic (total) order. First, all nodes are sorted alphabetically. Then, each node in the list is used as the start of a post-order depth-first search in which outgoing edges to unvisited nodes are traversed in alphabetical order of the successor nodes. Finally, nodes are printed in the reverse of the order in which they were visited.

`--[no]proto:rule_classes` default: "false"
:   Populate the rule\_class\_key field of each rule; and for the first rule with a given rule\_class\_key, also populate its rule\_class\_info proto field. The rule\_class\_key field uniquely identifies a rule class, and the rule\_class\_info field is a Stardoc-format rule class API definition.

    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

`--[no]relative_locations` default: "false"

`--[no]tool_deps` default: "true"
:   Query: If disabled, dependencies on 'exec configuration' will not be included in the dependency graph over which the query operates. An 'exec configuration' dependency edge, such as the one from any 'proto\_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same 'target' program.
    Cquery: If disabled, filters out all configured targets which cross an execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the exec configuration, only exec configured targets will be returned. This option will NOT exclude resolved toolchains.

`--universe_scope=&lt;comma-separated list of options&gt;` default: ""
:   A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands.
    For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.

    [`build_file_semantics`](#effect_tag_BUILD_FILE_SEMANTICS), [`non_configurable`](#metadata_tag_NON_CONFIGURABLE)

Options specifying or altering a generic input to a Bazel command that does not fall into other categories.:

`--flag_alias=<a 'name=value' flag alias&gt;` multiple uses are accumulated
:   Sets a shorthand name for a Starlark flag. It takes a single key-value pair in the form
    `&#123;key&#125;=&#123;value&#125;` as an argument.

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS), [`non_configurable`](#metadata_tag_NON_CONFIGURABLE)

Miscellaneous options, not otherwise categorized.:

`--deleted_packages=&lt;comma-separated list of package names&gt;` multiple uses are accumulated
:   A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path.
    Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package\_path entry. Specifying --deleted\_packages x/y avoids this problem.

`--[no]fetch` default: "true"
:   Allows the command to fetch external dependencies. If set to false, the command will utilize any cached version of the dependency, and if none exists, the command will result in failure.

`--package_path=&lt;colon-separated list of options&gt;` default: "%workspace%"
:   A colon-separated list of where to look for packages. Elements beginning with '%workspace%' are relative to the enclosing workspace. If omitted or empty, the default is the output of 'bazel info default-package-path'.

`--[no]show_loading_progress` default: "true"
:   If enabled, causes Bazel to print "Loading package:" messages.

## Run Options

Inherits all options from [build](#build).

Options that appear before the command and are parsed by the client:

`--[no]portable_paths` default: "false"
:   If true, includes paths to replace in ExecRequest to make the resulting paths portable.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--[no]run` default: "true"

    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--run_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies the set of environment variables available to the target to run. Variables can be either specified by name, in which case the value will be taken from the invocation environment, by the <code>name=value</code> pair which sets the value independent of the invocation environment, or by <code>=name</code>, which unsets the variable of that name. This option can be used multiple times; for options given for the same variable, the latest wins, options for different variables accumulate. Note that the executed target will generally see the full environment of the host except for those variables that have been explicitly unset.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

`--[no]run_in_cwd` default: "false"
:   If true, runs the target in the current working directory instead of the runfile tree.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS)

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--script_path=<a path&gt;` default: see description
:   If set, write a shell script to the given file which invokes the target. If this option is set, the target is not run from bazel. Use 'bazel run --script\_path=foo //foo && ./foo' to invoke target '//foo' This differs from 'bazel run //foo' in that the bazel lock is released and the executable is connected to the terminal's stdin.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`execution`](#effect_tag_EXECUTION)

Options that affect the verbosity, format or location of logging:

`--[no]omit_run_args` default: "true"
:   Specifies whether the arguments passed to the runnable target will be omitted from the output for privacy reasons. If set to true, the output will not contain the arguments passed to the target. If set to false, the output will contain the arguments passed to the target.

    Tags:
    [`terminal_output`](#effect_tag_TERMINAL_OUTPUT)

## Shutdown Options

Options that control the output of the command:

`--iff_heap_size_greater_than=&lt;an integer&gt;` default: "0"
:   Iff non-zero, then shutdown will only shut down the server if the total memory (in MB) consumed by the JVM exceeds this value.

## Test Options

Inherits all options from [build](#build).

Options that affect the verbosity, format or location of logging:

`--[no]print_relative_test_log_paths` default: "false"
:   If true, when printing the path to a test log, use relative path that makes use of the 'testlogs' convenience symlink. N.B. - A subsequent 'build'/'test'/etc invocation with a different configuration can cause the target of this symlink to change, making the path printed previously no longer useful.

## Vendor Options

Inherits all options from [test](#test).

Options that control build execution:

`--[no]keep_going` [`-k`] default: "false"
:   Continue as much as possible after an error. While the target that failed and those that depend on it cannot be analyzed, other prerequisites of these targets can be.

    [`eagerness_to_exit`](#effect_tag_EAGERNESS_TO_EXIT)

`--loading_phase_threads=&lt;an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]&lt;float&gt;) eg. "auto", "HOST_CPUS*.5"&gt;` default: "auto"
:   Number of parallel threads to use for the loading/analysis phase.Takes an integer, or a keyword ("auto", "HOST\_CPUS", "HOST\_RAM"), optionally followed by an operation ([-|*]&lt;float&gt;) eg. "auto", "HOST\_CPUS*.5". "auto" sets a reasonable default based on host resources. Must be at least 1.

    Tags:
    [`bazel_internal_configuration`](#effect_tag_BAZEL_INTERNAL_CONFIGURATION)

This option affects semantics of the Starlark language or the build API accessible to BUILD files, .bzl files, or WORKSPACE files.:

`--[no]incompatible_config_setting_private_default_visibility` default: "false"
:   If incompatible\_enforce\_config\_setting\_visibility=false, this is a noop. Else, if this flag is false, any config\_setting without an explicit visibility attribute is //visibility:public. If this flag is true, config\_setting follows the same visibility logic as all other rules. See https://github.com/bazelbuild/bazel/issues/12933.

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

`--[no]incompatible_enforce_config_setting_visibility` default: "true"
:   If true, enforce config\_setting visibility restrictions. If false, every config\_setting is visible to every target. See https://github.com/bazelbuild/bazel/issues/12932.

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

Options relating to Bzlmod output and semantics:

`--repo=<a string&gt;` multiple uses are accumulated
:   Only vendors the specified repository, which can be either `@apparent_repo_name` or
    `@@canonical_repo_name`. This option can be set multiple times.

    Tags:
    [`changes_inputs`](#effect_tag_CHANGES_INPUTS)

Miscellaneous options, not otherwise categorized.:

`--deleted_packages=&lt;comma-separated list of package names&gt;` multiple uses are accumulated
:   A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path.
    Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package\_path entry. Specifying --deleted\_packages x/y avoids this problem.

`--[no]fetch` default: "true"
:   Allows the command to fetch external dependencies. If set to false, the command will utilize any cached version of the dependency, and if none exists, the command will result in failure.

`--package_path=&lt;colon-separated list of options&gt;` default: "%workspace%"
:   A colon-separated list of where to look for packages. Elements beginning with '%workspace%' are relative to the enclosing workspace. If omitted or empty, the default is the output of 'bazel info default-package-path'.

`--[no]show_loading_progress` default: "true"
:   If enabled, causes Bazel to print "Loading package:" messages.

Options that control build execution:

`--[no]experimental_persistent_aar_extractor` default: "false"
:   Enable persistent aar extractor by using workers.

    Tags:
    [`execution`](#effect_tag_EXECUTION), [`experimental`](#metadata_tag_EXPERIMENTAL)

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`execution`](#effect_tag_EXECUTION), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]experimental_split_coverage_postprocessing` default: "false"
:   If true, then Bazel will run coverage postprocessing for test in a new spawn.

    Tags:
    [`execution`](#effect_tag_EXECUTION), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]experimental_strict_fileset_output` default: "false"
:   If this option is enabled, filesets will treat all output artifacts as regular files. They will not traverse directories or be sensitive to symlinks.

    Tags:
    [`execution`](#effect_tag_EXECUTION), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]incompatible_modify_execution_info_additive` default: "true"
:   When enabled, passing multiple `--modify_execution_info` flags is additive.
    When disabled, only the last flag is taken into account.

    Tags:
    [`execution`](#effect_tag_EXECUTION), [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS), [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

`--modify_execution_info=&lt;regex=[+-]key,regex=[+-]key,...&gt;` multiple uses are accumulated
:   Add or remove keys from an action's execution info based on action mnemonic.
    Applies only to actions which support execution info. Many common actions
    support execution info, e.g. Genrule, CppCompile, Javac, StarlarkAction,
    TestRunner. When specifying multiple values, order matters because
    many regexes may apply to the same mnemonic.

    Syntax: `regex=[+-]key,regex=[+-]key,...`.

    Examples:

    * `.*=+x,.*=-y,.*=+z` adds `x` and `z` to, and removes `y` from, the execution info for all actions.
    * `Genrule=+requires-x` adds `requires-x` to the execution info for all Genrule actions.
    * `(?!Genrule).*=-requires-x` removes `requires-x` from the execution info for all non-Genrule actions.

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--action_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies the set of environment variables available to actions with target
    configuration. Variables can be either specified by `name`, in which case
    the value will be taken from the invocation environment, by the `name=value`
    pair which sets the value independent of the invocation environment, or by
    `=name`, which unsets the variable of that name. This option can be used

`--runs_per_test=<a positive integer or test_regex@runs. This flag may be passed more than once&gt;` multiple uses are accumulated
:   Specifies number of times to run each test. If any of those attempts fail for any
    reason, the whole test is considered failed. Normally the value specified is
    just an integer.

    Example: `--runs_per_test=3` will run all tests 3 times.

    Alternate syntax: `regex_filter@runs_per_test`. Where `runs_per_test` stands for
    an integer value and `regex_filter` stands for a list of include and exclude
    regular expression patterns (Also see --instrumentation\_filter).

    Example: `--runs_per_test=//foo/.*,-//foo/bar/.*@3` runs all tests in `//foo/` except
    those under `//foo/bar` three times. This option can be passed multiple times. The most
    recently passed argument that matches takes precedence. If nothing matches,
    the test is only run once.

`--test_env=<a 'name[=value]' assignment with an optional value part or the special syntax '=name' to unset a variable&gt;` multiple uses are accumulated
:   Specifies additional environment variables to be injected into the test runner
    environment. Variables can be either specified by `name`, in which
    case its value will be read from the Bazel client environment, or by the
    `name=value` pair.
    Previously set variables can be unset via `=name`.
    This option can be used multiple times to specify several variables.
    Used only by the 'bazel test' command.

    positive integer value is specified it will override all categories. If 4
    comma-separated integers are specified, they will override the timeouts for
    `short`, `moderate`, `long` and `eternal` (in that order). In either form, a value of
    -1 tells blaze to use its default timeouts for that category.

    [`execution`](#effect_tag_EXECUTION)

`--[no]trim_test_configuration` default: "true"
:   When enabled, test-related options will be cleared below the top level of the build. When this flag is active, tests cannot be built as dependencies of non-test rules, but changes to test-related options will not cause non-test rules to be re-analyzed.

Options that affect the verbosity, format or location of logging:

`--toolchain_resolution_debug=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths&gt;` default: "-.\*"
:   Print debug information during toolchain resolution. The flag takes a regex, which is checked against toolchain types and specific targets to see which to debug. Multiple regexes may be separated by commas, and then each regex is checked separately. Note: The output of this flag is very complex and will likely only be useful to experts in toolchain resolution.

Options specifying or altering a generic input to a Bazel command that does not fall into other categories.:

`--flag_alias=<a 'name=value' flag alias&gt;` multiple uses are accumulated
:   Sets a shorthand name for a Starlark flag. It takes a single key-value pair in the form
    `&#123;key&#125;=&#123;value&#125;` as an argument.

`--[no]incompatible_default_to_explicit_init_py` default: "false"
:   This flag changes the default behavior so that **init**.py files are no longer automatically created in the runfiles of Python targets. Precisely, when a py\_binary or py\_test target has legacy\_create\_init set to "auto" (the default), it is treated as false if and only if this flag is set. See https://github.com/bazelbuild/bazel/issues/10076.

Miscellaneous options, not otherwise categorized.:

`--[no]cache_test_results` [`-t`] default: "auto"
:   If set to `auto`, Bazel reruns a test if and only if:

    1. Bazel detects changes in the test or its dependencies,
    2. The test is marked as `external`,
    3. Multiple test runs were requested with `--runs_per_test`, or
    4. The test previously failed.
       If set to `yes`, Bazel caches all test results except for tests marked as
       `external`. If set to `no`, Bazel does not cache any test results.

`--[no]experimental_cancel_concurrent_tests` default: "never"
:   If `on_failed` or `on_passed`, then Blaze will cancel concurrently running tests on the first
    successful run with that result. This is only useful in combination with
    `--runs_per_test_detects_flakes`.

    Tags:
    [`affects_outputs`](#effect_tag_AFFECTS_OUTPUTS), [`experimental`](#metadata_tag_EXPERIMENTAL)

`--[no]explicit_java_test_deps` default: "false"
:   Explicitly specify a dependency to JUnit or Hamcrest in a java\_test instead of accidentally obtaining from the TestRunner's deps. Only works for bazel right now.

`--host_java_launcher=<a build target label&gt;` default: see description
:   The Java launcher used by tools that are executed during a build.

`--host_javacopt=<a string&gt;` multiple uses are accumulated
:   Additional options to pass to javac when building tools that are executed during a build.

`--host_jvmopt=<a string&gt;` multiple uses are accumulated
:   Additional options to pass to the Java VM when building tools that are executed during the build. These options will get added to the VM startup options of each java\_binary target.

`--[no]incompatible_check_sharding_support` default: "true"
:   If true, Bazel will fail a sharded test if the test runner does not indicate that it
    supports sharding by touching the file at the path in `TEST_SHARD_STATUS_FILE`.
    If false, a test runner that does not support sharding will lead to all tests
    running in each shard.

    [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

`--[no]incompatible_exclusive_test_sandboxed` default: "true"
:   If true, exclusive tests will run with sandboxed strategy. Add `local` tag to force
    an exclusive test run locally

    Tags:
    [`incompatible_change`](#metadata_tag_INCOMPATIBLE_CHANGE)

`--[no]incompatible_strict_action_env` default: "true"
:   If true, Bazel uses an environment with a static value for PATH and does not
    inherit `LD_LIBRARY_PATH`. Use `--action_env=ENV_VARIABLE` if you want to
    inherit specific environment variables from the client, but note that doing so
    can prevent cross-user caching if a shared cache is used.

`--j2objc_translation_flags=&lt;comma-separated list of options&gt;` multiple uses are accumulated
:   Additional options to pass to the J2ObjC tool.

`--java_debug`
:   Causes the Java virtual machine of a java test to wait for a connection from a JDWP-compliant debugger (such as jdb) before starting the test. Implies -test\_output=streamed.

    Expands to:

      `--test_arg=--wrapper_script_flag=--debug`

`--shell_executable=<a path&gt;` default: see description
:   Absolute path to the shell executable for Bazel to use. If this is unset, but the
    `BAZEL_SH` environment variable is set on the first Bazel invocation (that starts
    up a Bazel server), Bazel uses that. If neither is set, Bazel uses a hard-coded
    default path depending on the operating system it runs on;

    * Windows: `c:/msys64/usr/bin/bash.exe`
    * FreeBSD: `/usr/local/bin/bash`
    * All others: `/bin/bash`.

    [`loading_and_analysis`](#effect_tag_LOADING_AND_ANALYSIS)

`--test_arg=<a string&gt;` multiple uses are accumulated
:   Specifies additional options and arguments that should be passed to the test

    Used only by the `bazel test` command.

`--test_filter=<a string&gt;` default: see description
:   Specifies a filter to forward to the test framework. Used to limit the tests run. Note that this does not affect which targets are built.

`--test_result_expiration=&lt;an integer&gt;` default: "-1"
:   This option is deprecated and has no effect.

`--[no]test_runner_fail_fast` default: "false"
:   Forwards fail fast option to the test runner. The test runner should stop execution upon first failure.

`--test_sharding_strategy=&lt;explicit, disabled or forced=k where k is the number of shards to enforce&gt;` default: "explicit"
:   Specify strategy for test sharding:

    * `explicit` to only use sharding if the `shard_count` `BUILD` attribute is
      present.
    * `disabled` to never use test sharding.
    * `forced=k` to enforce `k` shards for testing regardless of the `shard_count` `BUILD`
      attribute.

:   The Java runtime version used to execute tools during the build

`--[no]use_ijars` default: "true"
:   If enabled, this option causes Java compilation to use interface jars. This will result in faster incremental compilation, but error messages can be different.

## Version Options

Options that let the user configure the intended output, affecting its value, as opposed to its existence:

`--[no]gnu_format` default: "false"
:   If set, write the version to stdout using the conventions described in the GNU standards.

### Option Effect Tags

|  |  |
| --- | --- |
| `unknown` | This option has unknown, or undocumented, effect. |
| `no_op` | This option has literally no effect. |
| `loses_incremental_state` | Changing the value of this option can cause significant loss of incremental state, which slows builds. State could be lost due to a server restart or to invalidation of a large part of the dependency graph. |
| `changes_inputs` | This option actively changes the inputs that bazel considers for the build, such as filesystem restrictions, repository versions, or other options. |
| `affects_outputs` | This option affects bazel's outputs. This tag is intentionally broad, can include transitive affects, and does not specify the type of output it affects. |
| `build_file_semantics` | This option affects the semantics of BUILD or .bzl files. |
| `bazel_internal_configuration` | This option affects settings of bazel-internal machinery. This tag does not, on its own, mean that build artifacts are affected. |
| `loading_and_analysis` | This option affects the loading and analysis of dependencies, and the building of the dependency graph. |
| `execution` | This option affects the execution phase, such as sandboxing or remote execution related options. |
| `host_machine_resource_optimizations` | This option triggers an optimization that may be machine specific and is not guaranteed to work on all machines. The optimization could include a tradeoff with other aspects of performance, such as memory or cpu cost. |
| `eagerness_to_exit` | This option changes how eagerly bazel will exit from a failure, where a choice between continuing despite the failure and ending the invocation exists. |
| `bazel_monitoring` | This option is used to monitor bazel's behavior and performance. |
| `terminal_output` | This option affects bazel's terminal output. |
| `action_command_lines` | This option changes the command line arguments of one or more build actions. |
| `test_runner` | This option changes the testrunner environment of the build. |

### Option Metadata Tags
