Exclude *.fxgraph files from e(fx)clipse when creating the JAR file

FXGraph is an Xtext DSL included in e(fx)clipse

.fxgraph files are seamlessly compiled into .fxml when running Eclipse, and should always be excluded from the build as they can be considered as source files.

P.S.: E(fx)clipse has been proposed as an Eclipse foundation project, and it's really the de-facto plugin to develop using JavaFX and Eclipse.

Forgot to add that a simple

jar.exclude '**/*.fxgraph' 

would be sufficient

This sounds like something for a e(fx)clipse plugin. I intend to keep this plugin IDE neutral.
