I think the bug is that https://github.com/bazelbuild/rules_go/blob/master/extras/gomock.bzl#L232 rule _gomock_prog_exec should not pass in the **kwargs. Or we pop the "mockgen_model_library" here https://github.com/bazelbuild/rules_go/blob/master/extras/gomock.bzl#L207. I can submit a PR to fix it if needed.
