bazel diff failing when running via bazelisk

[andre-dialpad]

When running bazel-diff with bazelisk I'm getting the following error:

Output

This error seems to only happen when installing bazel-diff via MODULE.bazel:

# MODULE.bazel
bazel_dep(name = "bazel-diff", version = "9.0.3")

VERSIONS:

(bash)$ java --version 
openjdk 21.0.8 2025-07-15
OpenJDK Runtime Environment (build 21.0.8+9-Ubuntu-0ubuntu124.04.1)
OpenJDK 64-Bit Server VM (build 21.0.8+9-Ubuntu-0ubuntu124.04.1, mixed mode, sharing)

(bash)$ javac --version 
javac 21.0.8

Managed to fix this error by adding on MODULE.bazel

bazel_dep(name = "grpc-java", version = "1.75.0")

[tinder-maxwellelliott]

@andre-dialpad Did you add that to Bazel-diff or to you repo?

[andre-dialpad]

@tinder-maxwellelliott yes.

# MODULE.bazel

bazel_dep(name = "grpc-java", version = "1.75.0")

# bazel diff
bazel_dep(name = "bazel-diff", version = "10.1.0")

It's worth to point out that even though it's working we are still getting some warnings and errors.

17:03:47  ERROR: Skipping '//external:all-targets': no such package 'external': //external package is not available since the WORKSPACE file is disabled, please migrate to Bzlmod or temporarily enable WORKSPACE via --enable_workspace. See https://bazel.build/external/migration#bind-targets.
17:03:48  
17:03:48  WARNING: --keep_going specified, ignoring errors. Results may be inaccurate

These messages only started to appear when we introduced bazel-diff via MODULE.bazel.

[tinder-maxwellelliott]

Yes as in you added it to your repo? Not to Bazel-diff? That's really strange since we are passing in BCR. I can add it if it's truly needed.

As for those logs can you try adding --excludeExternalTargets to generate-hashes?

[andre-dialpad]

@tinder-maxwellelliott The first "yes" was that I added those lines to my repo.

I've followed your previous advice and adding --excludeExternalTargets seems to have clear the errors and I didnt find any issue so far.

In think maybe logging the //external:all-targets as a warning instead of a error is probably better but I'm not sure.
