Importing protocol buffer definitions between Maven projects

Question

I currently manage a few separate Maven projects in which I use Protobufs as a serialization format and over the wire. I am using David Trott\'s maven-protoc plugin to generate

You can package your .proto files in a separate .jar/.zip in the project where they are generated, and publish them in your repository using a dedicated classifier. Using the assembly plugin might help here to publish something close to "source jars" that are built during releases.

Then, on projects using them, add previously created artifact as dependency. Use the dependency plugin with the "unpack-dependencies" goal, and bind it to a phase before "compile".
