java.lang.IllegalArgumentException: Null value not allowed as an environment variable: POM_PACKAGING

Question

Just spent 2 hours on this, running a Maven project from Jenkins.

All you need to do is run in your Jenkins Master: rm -rf jenkins/jobs/[project_name]/modules/*

after that you must(!!!) restart Jenkins.

Rerun your job, it should work.
