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?

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

Thanks, but it does not work either with the stopWait. – Patrizio
Maybe my computer is too slow, I change <stopWait>5</stopWait> to <stopWait>10</stopWait> and it works! Thank you! – Protest

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

Breve answered 31/10, 2013 at 5:39 Comment(5)
But its caused by Exception in thread "Shutdown" java.lang.NoClassDefFoundError: org/apache/jasper/runtime/JspApplicationContextImpl, How can that be fixed? – Illogic
Could you please be more specific about your answer? I added the dependencies of the article but makes nothing, still receiving the same response when Jetty is shutting down. – Patrizio
Will you please share your pom file – Breve
@Breve I managed to remove the ClassNotFoundException of the jasper.runtime by using this dependency <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jsp-2.1</artifactId> <version>6.0.0</version> </dependency>. Now the exception is shorter and remains the ClassNotFoundException of the groovy.runtime.dmg, which I tested by including all those dependencies in the article and none of them work. In fact, looks like the dependency is not from Groovy itself but a resource used by Groovy, it can be seen by the $371 at the end. – Patrizio
@TechCrunch, No, I could not solve it. I finally ended up using Arquillian for the Integration-Tests, it works good and does not throw any exception during nor after the execution of the tests. Follow this tutorial: Arquillian Get-Started – Patrizio

I solved this, adding this dependency 

        <dependency>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jsp-2.1</artifactId>
            <version>6.0.0</version>
          </dependency>
