Building Titan
Just to have a reference here...
The official page Chapter 55. Building Titan says it all with necessary detail.
It boils down to mvn clean install -DskipTests in a given git branch, e.g. titan09:
➜ titan git:(titan09) ✗ mvn clean install -DskipTests
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
