That is what i am saying.

You have installed JBOSS IDE and not just Eclipse IDE, and tha 
org.jbpm.core plugin for eclipse gives you the NPE.

i don't know either the reason why it gave you this.

the solution i gave you is that you could install a fresh Eclipse in 
another directory, run "mvn make-artifacts" into, and see if you could 
use the installed artifact with your app and maven..

The make-artifacts goals need to be call just the first time, after 
that, you will have all the necessary artifact in your repo.
