O arquivo pmd.html não é gerado

Senhores, o arquivo pmd.html não é gerado após executar mvn pmp:pmp mesmo com o plugin informado no pom junto com o executions. Estou aplicando isso em um dos projetos que tenho. Este projeto funciona como um container para outros submodulos dos sistemas onde adiciono os jars e jsps desses módulos. Vejam o pom.xml
