This only helps cause it moved to jar, using a plain plugin as before
wouldn't mean much so not sure it helps and debugging is as easy in both
cases so just a feature from my window but I get your point now, thanks.

Still you need to define how you do deploy that (can't be a single jar but
a subproject should stay a single jar) so you will need some maven work
there and yes it is already doable even if it looks hacky so I don't think
we should think we just need to wrap java tools but we should think maven
first there IMHO, the rush will just bring inconsistencies and miss the
target like the hsah module which should be usable inter maven
modules/subprojects to keep a clean deployment model and standardized IDE
support (while exception for mjar to have a few classes not in a module is
okish, it is less for modules which are full libs IMHO).
