Given a very simple Spring-Boot Java-application (see: https://gitlab.com/ksamaschke/cap-demo), I want to deploy this application on the developer sandbox.
It accepts the code, looks for a build pack, appears to work - but exits giving this error-message:
13:45:09.956: [STG.0] None of the buildpacks detected a compatible application
13:45:09.970: [STG.0] Exit status 222
How to deploy such an application then?
