Description

These protobuf definition files are being bundled in built artifacts:

google/protobuf/any.proto
google/protobuf/api.proto
google/protobuf/descriptor.proto
google/protobuf/duration.proto
google/protobuf/empty.proto
google/protobuf/field_mask.proto
google/protobuf/source_context.proto
google/protobuf/struct.proto
google/protobuf/timestamp.proto
google/protobuf/type.proto
google/protobuf/wrappers.proto

This is caused by the addProtoSources configuration of the protoc-jar-maven-plugin.

We should remove those, because:

• Bundling those will require licensing acknowledgement to Protobuf in our artifacts.
• Those definition files are not used directly by Stateful Functions at all.
