BTW tapestry-stitch has two modules (component library + webapp) and I develop in eclipse using m2e + RunJettyRun.
As you can see, StitchModule is added to the manifest here: https://github.com/uklance/tapestry-stitch/blob/master/pom.xml#L67 But also declared as a SubModule here for easy testing: https://github.com/uklance/tapestry-stitch-demo/blob/master/src/main/java/org/lazan/t5/stitch/demo/services/AppModule.java#L12
