             Project: CXF
          Issue Type: Bug
          Components: Build system, JAX-RS, JAXB Databinding
    Affects Versions: 2.5
         Environment: Apache Maven 2.2.1 (rdebian-4)

I want to create the client stubs with a .wadl file.
*Before you ask, it's not possible for me to attach the file due to an NDA.*

*Important:*
It works fine, if I don't use the {{<extraarg>-impl</extraarg>}} extraarg.

This is the maven plugin definition in the {{pom.xml}} file:

{code:xml} 
<plugin>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-wadl2java-plugin</artifactId>

            </execution>
    </executions>
</plugin>
{code} 

Then, after calling {{mvn clean generate-sources}}, I get this exception:
