Maven multi-module build options
# Inspired from http://blog.akquinet.de/2010/05/26/mastering-the-maven-command-line-%E2%80%93-reactor-options/
# Build only specific modules:
mvn clean install -pl sub-module-name2
mvn clean install -pl sub-module-name2,sub-module-name3
# Build only starting from specific sub-module (resume from)
mvn clean install -rf sub-module-name2
# Build dependencies (also make)
