Solution

If you are new to JavaFX I recommend you to check out this preconfigured non modular project and configure it to your needs:

https://github.com/davidweber411/SimpleJavaFxAppWithoutModules

Just download, extract, start, profit! Everything ist configured out of the box!

Alternative

You can create a running JavaFX project with this project generator:

GitHub link:

Homepage:

https://wedasoft.com/projects/javafx-project-generator/#

Note

I am the author of both.

There is a gradle task for creating am executable fat jar.
