From samual taul:

Error when trying to run windup (installed as coordinate) into forge plugin in JBDS8.

Steps to reproduce:

• run forge
• select -> "Install an Addon"
• specify the coordinates to windup (you will need to run this command once for each coordinate):
  org.jboss.windup:ui,2.0.0.Beta5
  org.jboss.windup.rules.apps:rules-java,2.0.0.Beta5
  org.jboss.windup.rules.apps:rules-java-ee,2.0.0.Beta5
• then run Windup via Forge in JBDS
• select "Windup Migrate App" and use the wizard to completion.
• filled the fields requested with the same values as I did using command line (which worked fine).
  I tested using the the provided app example: http://download.jboss.org/windup/jee-example-app-1.0.0.ear
