How are you?
Thanks for sharing the great project.
I love this and I want to use this library.
But I download project and tried to compile, but it occurs the exception and never run.
I can't see the running app.

Always get following exception. Would you check it please and give me hint?

Not sure how you try to start the demo but if you go to the gradle panel in IntelliJ, choose "tilesfxdemo" -> "Tasks" -> "other" -> "Demo" and double click it it should start. I've tested it on my machine and it works totally fine with JDK11 in IntelliJ 2020.2

[Chuntianhong]

Thanks for your answer.
I need to install JDK 11?

[MXHanner]

I use JDK11 and JavaFX11, and I get the same exception when I run the project both in Eclipse and IDEA. Could you please give me a hint? Is there something wrong with my configuration?
