GPMONGODB-385: exception when invoking "grails upgrade"

Original Reporter: clueless
Environment: Not Specified
Version: 3.0.0
Migrated From: http:https://jira.grails.org/browse/GPMONGODB-385

I get the following exception when attempting to upgrade grails and when creating a Controller through IntelliJ 13.

Note: removed actual dir paths below - replaced with "path" as they were not relevant to the exception
