I'm using Bazel to build a module that has a dependency on protobuf. Builds were successful until today when they started failing with the following error:

I've been trying to make sense of this error. My current interpretation is that no such package '@@rules_jvm_external++maven+protobuf_maven// means that Bazel is not able to find the Maven dependencies defined here. I wonder if this is because the flag dev_dependency is enabled here?

What's puzzling is that this build error only occurs when running the build on Google Cloud Build. Locally, the Build target builds successfully.

Does anyone have a suggestion for solving this? Thank you.
