I've modified the official maven-eclipse-plugin-1.9 a little so that it can generate eclipse .classpath file correctly in multiproject configurations (I can't find any good eclipse project file generator plugin for multiproject configuration, so I can hack myself. ). Hope it can help any agila developers that use eclipse as IDE. I've not fully tested it yet. It just works for me (though I think it should work well in other environments).
or if you want to add resource files
maven -Dmaven.eclipse.resources.addtoclasspath=true eclipse:generate-mpclasspath
(or put maven.eclipse.resources.addtoclasspath=true to project.properties)
