Don't run mvn eclipse:eclipse It's broken :/ However, you can make it work by editing the Parser.java, method setSchemaResources. Find line List<String> schemaLocations = new ArrayList<String>(resources.size()); and change it into Collection<String> schemaLocations = new HashSet<String>(resources.size()); This filters out the double jpdl.xsd that is placed twice on the classpath. Hope this helps. KR, Andries View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227411#...
