Release 9.0.0-pre.20250516.1 (2025-05-23)

Baseline: 9b8093bb4db3d6567e0f29eaa98fe16cd2e4a154

Incompatible changes:

  - Starlark computation step limits are now enforced for symbolic
    macros.

Important changes:

  - java_import.jars attributes can no longer be empty, and
    --noincompatible_disallow_java_import_empty_jars is no longer
    supported
  - Added `--verbose_visibility_errors` for printing more information
    when a visibility violation occurs.
  - Added a new flag `--repo_contents_cache` (defaults to the
    `contents` directory under the `--repository_cache`) where Bazel
    stores fetched contents of repos that can be safely cached across
    workspaces. A repo rule can indicate cacheability by returning
    `repository_ctx.repo_metadata(reproducible=True)` from its
    implementation function.

This release contains contributions from many people at Google, as well as Adin Cebic, Benjamin Peterson, Bo Zhang, Chris Sauer, dependabot[bot], Dmitry Ivankov, Fabian Meumertzheim, George Gensure, Grzegorz Lukasik, jacqueline.lee, Jonathan Schear, Thi Don, Xdng Yng.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel rebuilds only what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
