While this would I think work, it is duplicating code in gradle-build/action.yml. For that matter there is also some duplication in workflows/maven-snapshot.yml and workflows/maven-ci.yml for maven-build/action.yml as well. While I do think it would be better to not have duplicate code to maintain given this will still work I'm approving it and perhaps we can discuss offline with @thescouser89
