From a dependency perspective, this is what I am looking at (in bazel):

"""Common dependencies for rules_proto_grpc Java rules."""

For this project:

Porting basically the same code to a gradle bud resolves this. Anyone with Bazel and Flink expertise with thoughts in this would be much appreciated
