The maven jetty plugin is very popular and useful because it allows you to run a web application with a trivial command line execution "mvn jetty:run" and without setting up a servlet engine or deploying your app to it. Perhaps more importantly, it allows fast debug cycles in development. The plugin is misconfigured right now and I'm told its pedigree was a copy-paste from somewhere – it was never verified to work. Attached is a patch that configures it properly. There's not much to it.
