Error when use with bazel --output_base flag

when run with bazel --output_base bazel-cache run @hedron_compile_commands//:refresh_all I got the following error, can anyone provide help?

ERROR: error loading package 'bazel-hello_world/external/bazel_tools/src/conditions': Every .bzl file must have a corresponding package, but '//tools/windows:windows_config.bzl' does not have one. Please create a BUILD file in the same or any parent directory. Note that this BUILD file does not need to do anything except exist.
Bazel aquery failed. Command: ['bazel', 'aquery', "mnemonic('(Objc|Cpp|Cuda)Compile',deps(@//...))", '--output=jsonproto', '--include_artifacts=false', '--ui_event_filters=-info', '--noshow_progress', '--features=-compiler_param_file', '--features=-layering_check']

Hey @LittleCuteBug! Thanks for giving the tool a whirl. This is...a very strange one. Those are internal bazel tools failing to have been instantiated properly. Do things work properly if you remove the --output_base bazel-cache, add it to your bazelrc, or also pass it to our subcommands by appending -- --output_base bazel-cache (see the flag configuration section of the readme for more.)? I'm guessing the problem is that the tool is getting a different output base at runtime from compile time.

Hi @cpsauer, I have also tried the .bazelrc and -- --output_base bazel-cache and still have the same error.
Without the --output_base bazel-cache, the bazel run @hedron_compile_commands//:refresh_all works fine for me.

I'm guessing the problem is that the tool is getting a different output base at runtime from compile time.

Yes, I think that is the problem too.

Hi @cpsauer, I think I found the reason, it's because I set the output_base inside the workspace, so the hedron_compile_commands tried to check in that directory also.
Is there any way to exclude that directory?

commented

Oh! interesting. Sounds like all works fine if the output_base is outside the workspace? If so, this really seems like a Bazel bug...and worth reporting to them.
To help scope:

  • Are you indeed on Windows?
  • Does that aquery command (and simpler versions of it) also fail with the output_base set? (I'm trying to see if we can remove this tool from the equation.)
  • Excluding: Might a .bazelignore work? https://bazel.build/run/bazelrc#bazel-behavior-files

yes, I have managed to work with the combination of startup --output_base=bazel-cache in the .bazelrc and bazel-cache in the .bazelignore file.
A small interesting issue is the query command used in the hedron_compile_commands only takes effect of the .bazelrc when the hedron_compile_commands repo is imported by git_repository rule or local_repository rule. if I included it with http_archive, the .bazelrc config seems not to take effect.
