Question: make use of Maven Wrapper?

[Oliver-Loeffler]

To contribute to Scene Builder, one requires an installed JDK and Maven.

Expected Behavior

Ideally Scene Builder brings Maven with it, so the JDK setup is sufficient.
With having JDK installed, one can directly start to run/test Scene Builder from command line using mvnw.

Current Behavior

To work with Scene Builder, one has to install Maven upfront.
Without Maven installed, building, testing and running Scene Builder won't work.

Context

Make contributions / effort to get into contributing as easy as possible.
