[jbdevstudio-users] JBoss Knowledge Base Builder - NullPointerException (VirtualResource.getProjectRelativePaths(...))

[jbdevstudio-users at lists.jboss.org]

I am unable to get any content assistance in my xhtml pages, and I believe it is related to the error I get when building the project:

Platform:
Eclipse Java EE
Version: Kepler Service Release 1
Build id: 20130919-8019

JBoss Tools:
I am not sure which plugin versions are useful but here are some important looking ones:
JBoss AS Core Plug-in - 2.4.100.Final-v20130717-0846-B106
JBoss Tools Common - 3.5.1.Final-v20130717-0450-B102
Application Server Interface Core Plug-in - 2.4.100.Final-v20130717-0846-B106

El Plug-in - 3.5.1.Final-v20130717-0450-B102
