Dependency jar files are no longer scanned for .tld files with jetty-maven-plugin

Checking some archetypes for MyFaces Core project I notice the latest version of jetty does not work.

MyFaces has a listener entry in a .tld file, and that is not loaded or scanned anymore

I'll attach a example webapp for this one. Just type mvn clean -PjettyConfig jetty:run. With jetty 7.4.5.v20110725 works but if you change maven.jetty.plugin.version property inside the pom to 7.6.0.v20120127 it does not, throwing a ClassNotFoundException. Later, I added myfaces jars as dependencies for the plugin but the tlds are not scanned, so myfaces listener is not loaded and another exception occur (Factory not loaded). Later if I add:

<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

Into web.xml the app works, but contextPath is not added.
