Exception in application start method

I cannot run the project, I have also tried Tilesfx too and I'm getting the error mentioned below. Unable to launch the demo.

8:51:57 am: Executing task 'Demo.main()'...

This is the line where the program breaks and throw null pointer exception

Scene scene = new Scene(pane)

If you would like to start the demo from Intellij you either start the gradle task Demo that you can find in the list of other tasks in the gradle panel or you have to run the DemoLauncher class.
