 * `mvn clean install` - Full build including automatic QA and maven managed tests. Typical time: 5 minutes.
 * `mvn clean install -Pfast` - Building all distribution artifacts, running just unit tests, QA and integration tests excluded. Typical time: 3 minutes.
 * `mvn clean install -Pfastest` - Building all distribution artifacts, excluded all QA and testing. Typical time: 1.5 minutes.
