The richfaces-resources:process goal requires three required parameters:
mvn clean richfaces-resources:process -Dskins=blueSky -DstaticResourceMappingFile=target/configuration.txt -DresourcesOutputDir=target/processed-resources/
In most cases, you would need to configure build to generate files automatically.
Following configuration will take all @ResourceDependencies defined across project and its dependencies and pre-generate them to the given directory and generate configuration for RichFaces resource mapping.
