@jamezp I implemented your great comments. Thank-you!

[jfdenise]

@torsten-liermann , it would be great if you could validate that this solution works for you. You have been the main source of requirement for it! Thank-you.

Thank you for the quick implementation. The implementation works as expected for the example project. I would have designed the idea similarly to the maven-ear-plugin: deploying all dependencies defined in the pom.xml and structuring the "deployments" configuration analogous to the "modules" configuration.
