Feature to not deploy parent module of a multi-module project.

### New feature, improvement proposal

We have a multi-module project where the parent module has no actual content, and references child modules to be built. When we use `mvn deploy` to the Github Maven repository, Github refuses the upload of the parent module because there is no jar to upload. This causes all the child modules to not deploy either, since the parent module failed. Is there a way to avoid deploying the parent module?
