Python rules_proto_grpc causes Import errors? about rules_proto_grpc

[siva-tonita]

In particular, without the python_grpc_library dependency //A/B/C:baz_py_grpc. bazel run A/B:bar legitimately builds A:foo (as can be verified by the presence of A/__pycache__/ with foo.cpython-310.pyc inside it (this is all under bazel-bin/A/B/bar.runfiles/__main__/). Similarly, if we just run bazel build A:foolib, we see the __pycache__ dir.

However, with that dependency //A/B/C:baz_py_grpc, I am not seeing the __pycache__ directory, confirming that the target A:foolib is not built.

Have you tried setting legacy_create_init = False, on your py_binary? The default mode is somewhat broken how it handles overlapping import trees

Thank you for the suggestion; fixes our problem (for now; hopefully it will be easy to identify the missing __init__.py requirements in srcs and deps for any future breakages).

Closing the Issue with much appreciation for your help!
