Hi (hope I did not miss mails on this topic),
During test on maven NetCAT, testers are told to create and generate mavenized NetBeans Platform Module and Suite.
Maven archetype for Netbeans platform module  are linked to artefacts stored in  (RELEASE 6 to 8.2) and it is also possible to use snapshot versions from 
Artifacts are generated from Oracle NetBeans sources at the moment, RELEASE* artifact were built from a specific build, SNAPSHOT artifact are refreshed every day with no history (I suppose for space reason).
It would be nice to recreate a workflow to regenerate maven artefacts for the Apache NetBeans Platform from Apache NetBeans sources.
