About duplicate resources: If the resources is a jar thing you should just make a jar with the resources and depend on it when needed. But I think you mean resources of web type. like *.jsp, At least I found some of these when I did maven transformation of the portal (JIRA JBPORTAL-1615) And here the war plugin is able to depend on other war artifacts. So you can collect duplicate resources in a "base" war and depend on this one in the real war artifacts. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4086443#...
