    If your project build is done for example by `Maven` you could create a build step for the `generate` phase and later map this step to the build in eclipse with the `Lifecycle Mappings`. – SubOptimal Apr 12 '16 at 11:09
  • I don't believe you did thorough search as you can't tell difference between compiler and recognizing. Protoc is compiler that will generate ..java file, while to recognize you just need an Editor like https://marketplace.eclipse.org/content/minimalist-proto-files-editor-protocol-buffers-and-grpc.

Add below plugin in your pom.xml and put your proto files in src>main>proto folder and then right click on ur project Maven>Update Project.... After that clean ur project.
