[jbpm-dev] Error while building maven console

Hi! I checked out the gwt console and tried to build is as decribed here: https://www.jboss.org/community/docs/DOC-12879 And my antipathy against Maven rose again, after downloading the internet the build failed. Seems to be something wrong with the maven dependencies? Maybe anybody has a spontaneous idea whats wrong here? Thanks a lot and cheers Bernd
