Description

I'm still trying to find out the best way to use the Maven Jetty Plugin, so I might be doing something wrong on this side here.

Nevertheless, when I run mvn package on my project while the server is running (to update dependent libraries to the server), I get the following error:

Above is all console output from the moment the server sees the new files.

This exception prevents the webapp from booting.

PS. Note the typo in the package name: "org.apache.myfaces.extensions.scripting.jsf.dynamicdecorators.implemetations"...
