How do I enable jetty-maven-plugin 8 server debug output?

Question

I'm trying to upgrade our jetty from 7 to 8 so that we can take advantage of servlet 3.0. It doesn't appear that any settings or configuration changes were made from 7 to 8. Previously we've been using jetty-maven-plugin 7.2.0.RC0 to mvn jetty:run (along with catalina 6.0.29, slf4j 1.5.9 and servlet 2.5). When updating jetty, I had to add in the slf4j, log4j and javax.servlet-api dependencies to the plugin so that there wouldn't be API problems. The catalina dependency has always been there. Here's the pom now:

  <plugin>

        </connector>
      </connectors>
    </configuration>
  </plugin>

My problem is that I'm no longer seeing the kind of debug output that I expect to see. In jetty 7 when I did mvn jetty:run I'd see something like

org.mortbay.jetty.plugin.JettyServer@271bc503 STOPPED +-SelectChannelConnector@0.0.0.0:8080 +-SslSocketConnector@0.0.0.0:8443 +-qtp62871287{8<=5<=8/254,0} +-HandlerCollection@c237b89 started +-ContextHandlerCollection@6d836598 started | +-JettyWebAppContext@17043b2f@17043b2f/widgets,[file:/Users/dwinsor/previ ... ... [INFO] Started Jetty Server

Now, however, all I see is the last line, [INFO] Started Jetty Server. I want to be able to see all the pretty WebAppContext output. I've tried -Dorg.eclipse.jetty.util.log.DEBUG=true and -Dorg.eclipse.jetty.LEVEL=DEBUG, yet we weren't using either of these before anyways. How can I enable this output?

Thank you.

The problem was at jetty 7.3.0 the debug output seen is no longer printed out unless certain properties were set in jetty.xml:

<Set name="dumpAfterStart">true</Set>

<Set name="dumpBeforeStop">true</Set>
