Import Maven Project: java.lang.NullPointerException     at org.jboss.ide.eclipse.as.wtp.core.vcf.ExportedClassFolderReferenceResolver.canResolve(ExportedClassFolderReferenceResolver.java:36)     at org.eclipse.wst.common.componentcore.resolvers.ReferenceResolverUtil.getResolver(ReferenceResolverUtil.java:43)     at org.eclipse.wst.common.componentcore.internal.StructureEdit.createVirtualReference(StructureEdit.java:326)     at org.jboss.ide.eclipse.as.wtp.core.vcf.JBTVirtualComponent.getHardReferences(JBTVirtualComponent.java:106)     at org.jboss.ide.eclipse.as.wtp.core.vcf.JBTVirtualComponent.getReferences(JBTVirtualComponent.java:76)     at org.maven.ide.eclipse.wtp.overlay.internal.servers.OverlayResourceChangeListener.hasOverlayChanged(OverlayResourceChangeListener.java:117)     at org.maven.ide.eclipse.wtp.overlay.internal.servers.OverlayResourceChangeListener.resourceChanged(OverlayResourceChangeListener.java:60)     at org.eclipse.core.internal.events.NotificationManager$1.run(NotificationManager.java:291) ... Seems that "ReferencedComponent.getHandle()" returns null. Project builds with mvn OK, project import doesn't complete with NPE above, in Eclipse Indigo, m2e and m2e-wtp, with jBoss Tools Maven integration. Other projects in workspace (EAR, WAR, Dynamic Web Modules) import and build OK and work with m2e-wtp OK. How can I resolve this? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/643854#643854] Start a new discussion in JBoss Tools at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
