The ruta-parent pom has an extraneous clause: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-gpg-plugin</artifactId> <version>1.6</version> </plugin> <plugin>
This should be removed. - It is in the build / plugins section (not plugin-management) but specifies no goals or other configuration - it specifies a version (1.6) but that's already being inherited from the apache-wide superpom. (not a blocker). -Marshall
