Did a quick google & couldn't see one yet - please close if there is one already
The really nice thing about jetty:run is it watches the source code & target/classes dir & auto redeploys on change, so there's no deploy step - you just hack & compile (which your IDE or incremental compile can do - e.g. "mvn scala:cc").
For added bonus would be being able to add some extra bundles, so it can be a RAD way to hack bundles. Maybe folks could have some integration junit tests automatically rerun whenever the bundle is redeployed?
