Bazel 3.7

Bazel 3.7 is a minor release. It is an incremental update to Bazel 3.6.

Incompatible changes

  • The syntax //foo/BUILD can no longer be used on the command line to refer to the //foo:BUILD target. Use //foo:BUILD (preferred) or foo/BUILD instead. This does not affect BUILD/bzl files, where that syntax already didn't work.
  • Remove the --objc_header_scanner_tool flag. The flag was primarily used internally, and to our knowledge, a compatible tool was never released. Therefore this flag is believed to be unused.


  • Non-android targets are not in error when android_sdk_repository is present but invalid.


  • Include resources attribute in dependency attributes for java_* coverage configuration.
  • Javac now supports multiplex workers, but it is not enabled in the toolchain.

Other changes

  • select() directly supports constraint_value with no need for an intermediate config_setting.
  • --trim\_test\_configuration should work for almost all cases when a non-test target depends on a test.
  • Bazel now allows symbolic links that point to their own ancestor unless they are traversed recursively by e.g. a //... recursive target pattern or a recursive glob.
  • Generated Go protobufs no longer depend on //net/proto2/go:proto
