Moving Drools DRL between packages leaves residual DRL information in workspace environment, causing ResourceException, Resource does not exist
-----------------------------------------------------------------------------------------------------------------------------------------------

                 Key: JBRULES-2491
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2491
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-eclipse
    Affects Versions: 5.1.0.M2
         Environment: Helios 3.6M5, Drools 5.1.0.SNAPSHOT
            Reporter: Eric Lindahl
            Assignee: Mark Proctor
            Priority: Minor


Aparently, Drools builder is attempting to build a file that has moved but has an editor descriptor that no longer exists because the underlying DRL was moved to another package.
The workspace.xml has an <editor/> entry that still refers to the old package, and Drools Eclipse is trying to build it.
There may be other problems and workarounds due to this.
