Alguém conhece aplicativos da Web criados com o Maven para um RPM? ORPM Maven Plugin fornece a funcionalidade para criar um RPM, mas está faltando documentaçã

Especificamente, estou procurando um exemplo que inclua vários módulos, ou seja,Capítulo 8. Um Projeto com Vários Módulos, da série "Maven by Example"

Um exemplo com apenas um único módulo seria:
