The depchain has artifactId `push-depchain`, but `richfaces-push` is specified here (that's why the CI job failed: https://buildhive.cloudbees.com/job/richfaces/job/richfaces5/138/org.richfaces.examples$push-demo/console )

I like the `richfaces-` artifacts prefixing:

* `richfaces-push:pom`
* `richfaces-push-depchain:pom`
