Hey Mauricio,
Thanks for the fast reply.
I've replaced the maven and github repositories to the C-drive and than the build worked :-) , so potentially windows users with default settings could have the same build issue.
performing a mvn gwt:run, the jetty server returns an 503 error both in Chrome as in Firefox, is this as expected?:

But I when deploying the distribution war file to Jboss, all works well.
Thanks!
