protoc is the compiler for .proto files. It generates language bindings for the messages and/or RPC services from .proto files. protoc is a native executable, the scripts under this directory build and publish a protoc executable (a.k.a. artifact) to Maven repositories. The artifact can be used by build automation tools so that users would not need to compile and install protoc for their systems.

I've been using protoc to generate golang gRPC client and server code without issues. Since I have multiple gRPC services that use the same data types, I'd like to refer to a base.proto for these types rather than copy and paste, which is extra…
