When running the build in the persistence example with sub-modules address-book and roster fail on build:

I'm not affiliated with this project but it looks like a space in your ${basedir} path (between "Competence" and "Area") is being interpreted as the start of a new javac option. It's likely an issue with (or expected behaviour from) the maven-processor-plugin. They live over here if you want to get in touch.

For what it's worth, I've recently run the glassfish5 version of the address-book example without any issues.

*edit: looks like someone else has had a similar issue with the plugin and it may be able to be addressed by a change to the code here. If the fix there works, I might knock up a quick PR to clean up things on this side.

Yes, clearly a bug in the maven-processor-plugin. To workaround that bug, rename your directory to not include a space in the name.
