gradle javafx runtime components are missing and are required to run this application

1/* 
2For example, you can have a main class that is not extending javafx.application.Application,
3and that main class can then call the main(String[]) method on your real main class
4(that way, the Java launcher doesn't require the javafx libraries to be available as named modules).

8// Your JavaFX Class
9public class YourJavaFXApplication extends Application {
10    public static void main(String[] args) {
11        launch(args);
12    }

14    @Override
15    public void start(Stage primaryStage) {
16        // Your JavaFx stuff
17    }
18}
19
20// Your Main class which only purpose is to start your JavaFX class
21public class Main {
22    public static void main(String[] args) {
23        YourJavaFXApplication.main(args);
24    }
