I am running an Integration test with Maven, Selenium and Jetty. The tests are executed OK, but when the server are shutting down then the Jetty server throws a java.lang.ClassNotFoundException: org.codehaus.groovy.runtime.dgm$371. Here's the complete stack trace:

Any idea why is this happening?

Looks like groovy runtime dependency missing. Please refer http://docs.codehaus.org/display/GMAVEN/Groovy+Runtime

Try adding a stopWait to the jetty configuration :

<configuration>
  <scanIntervalSeconds>10</scanIntervalSeconds>
  <stopKey>stop</stopKey>
  <stopPort>8005</stopPort>

  <stopWait>5</stopWait>

</configuration>

This ensures jetty stops before the next maven goal is executed and importantly before the build completes.

It's this case where Jetty is attempting shutdown when the Maven build has completed that you will see this ClassNotFoundError.

See also http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html#jetty-stop-goal
