Ensemble is a set of samples for JavaFX 2. Unfortunately, it is only available as a NetBeans project, and through an Ant build.
This project is a port of Ensemble to Maven so that IntelliJ IDEA and Eclipse users can also play with JavaFX.
JavaFX is included in the JRE but on the classpath. Run the following to fix it:
sudo mvn com.zenjava:javafx-maven-plugin:2.0:fix-classpath
