Roll forward execroot change RELNOTES[INC]: Previously, an external repository would be symlinked into the execution root at execroot/local_repo/external/remote_repo. This changes it to be at execroot/remote_repo. This may break genrules/Skylark actions that hardcode execution root paths. If this causes breakages for you, ensure that genrules are using $(location :target) to access files and Skylark rules are using http://bazel.io/docs/skylark/lib/File.html's path, dirname, etc. functions. Custom crosstools that hardcode external/<repo> paths will have to be updated. Issue #1262. -- PiperOrigin-RevId: 147726370 MOS_MIGRATED_REVID=147726370
{Fast, Correct} - Choose two
Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:
A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.
An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.
Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
