Description

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:

                    </goals>
            </execution>
    </executions>
</plugin>

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