Hi Herman,
I am not sure if your question is “Does it generate m2ee.yaml in a Docker build?” or “Can I use this to auto-generate m2ee.yaml for my stand alone server?”
If the first one, then yes. It essentially creates a Docker container and then downloads and runs the exact same build scripts from the CF Buildpack GitHub.
If the second one, then perhaps but I have never managed to actually find the m2ee.yaml file itself, as I think it works a bit differently to the stand alone server.
I know it is a bit late, but I hope this helps.
