---------------------------------------

Hi Andrew! Thanks for the patch. Should we simply look at the modification times of the protoc files and the generated files?

> The protoc maven plugin currently generates new Java classes every time, which means Maven always picks up changed files in the build. It would be better if the protoc plugin only generated new Java classes when the source protoc files change.
