Tras un par de horitas adaptando el decompilado de un plugin para Jenkins/Hudson he conseguido "solucionar" el error que indico más arriba. La solución (workaround) es la siguiente:

En la configuración del plugin del compilador (en el pom.xml ) hay que poner lo siguiente:

            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                    <compilerArguments>
                        <proc:none />
                    </compilerArguments>
                </configuration>
            </plugin>

 También podemos pasarlo a maven como una propiedad: -Dproc:none

Con esta modificación conseguiremos que maven compile e instale el plugin en jenkins para poder probarlo y/o depurarlo
