An appropriate version of :protobuf-java dependency has to be declared, or made available through POM inheritance: this is needed for compiling the generated source code.Note: test-compile goal will only be needed if there are custom protocol buffer definitions being used in your tests. However, plugin goals have default bindings to appropriate phases, therefore there is typically no need to specify phase bindings in plugin configuration. Plugin executions need to be defined, because the plugin is not part of the default lifecycle.An alternative configuration involves toolchains (described in plugin examples).
