I'm trying to create JavaFX project with Java 11 using Maven. I have added dependencies to the POM file, but when I try to run the application I get error:

JavaFX runtime components are missing, and are required to run this application.

If I run the application using Java 8 SE it launches and works normally.

I look at other SO posts but I can't find the solution. I tried to create new main file that then calls Application(myApplicationClass.class, args)

public class Main {
    public static void main(String[] args) {
        Application.launch(Launcher.class, args);
    }
}

but then I get this error:

Exception in thread "WindowsNativeRunloopThread" java.lang.NoSuchMethodError: <init>

This is my Launcher class:

public class Launcher extends Application {

   public static void main(String[] args) {
       launch(args);
   }

   @Override
   public void start(Stage primaryStage) {
       Scene rootScene = new MainMenu();
       AppContext.init(primaryStage, rootScene);

       primaryStage.setResizable(false);
       primaryStage.show();
   }

And this is my POM.xml

  • How do you run the app in the first case? From Eclipse (like a Java application) or from Maven (`mvn compile exec:java`)? For the second error, edit your question and post the launcher class. – José Pereda Apr 01 '19 at 11:04
  • Both time I run from Eclipse. I added the code for the second error. – ColdBlade97 Apr 01 '19 at 11:29

    Running from Eclipse you have to configure the module-path options. See https://openjfx.io/openjfx-docs/#IDE-Eclipse. The launcher is wrong, see this [NewMain](https://stackoverflow.com/a/52654791/3956070) for a valid launcher class. – José Pereda Apr 01 '19 at 11:32

I encountered the same problem using both OpenJDK version 12 and Oracle JDK version 12.

As a temporary solution, I reverted to Oracle JDK version 8. This eliminated the error.
