org.codehaus.plexus.component.configurator.ComponentConfigurationException:
Class 'java.util.List' cannot be instantiated
at
that indicates that it is trying to make a List, when it needs to be making

could you paste the relevant portion of the pom.xml? and you meant
pom.xmland not
project.xml below, right?
