JavaFX in Eclipse Helios: IllegalArgumentException (Css2Bin.java:44)

Question

I got this error while trying to start and make javafx 2.0 in eclipse helios

Exception in thread "main" java.lang.IllegalArgumentException: expected         


        

Answer 1

if you don't depend on running in helios I'd suggest you'd give e(fx)clipse a try. You can find it at http://www.efxclipse.org/

Answer 2

Well, these answers seem to say what you need to do, but they're not very straight-forward.

1. You right click the project, and click Properties.
2. Select Run/Debug Settings.
3. Click Css2Bin.
4. Delete it.

Trust me I tried it and it works.

Answer 3

It's easy you need to have a main Class that extends Application Class for Launch the Args like that :

public class Test extends Application {

    public static void main(String[] args) {

        // Launch the Application 
        launch(args);   

    }

    @Override
    public void start(Stage primaryStage) throws Exception {

        //JavaFx load the GUI from FXML file ... super 
        Parent root = FXMLLoader.load(getClass().getResource("yourGUI.fxml"));
        primaryStage.setTitle("App Name");
        primaryStage.setScene(new Scene(root));
        primaryStage.show();

    }

}

Answer 4

Assume you have added jfxrt.jar into reference libraries...

Now

Right Click your Project -> Properities -> Run/Debug Settings -> Click the Css2Bin ->

Main Class:

Click the Search button

to change com.sun.javafx.css.parser.Css2Bin into your project main class

and

Mark the checkbox

• Include system libraries when searching for a main class
• Include inherited mains when searching for a main class

Answer 5

• Add the jfxrt.jar to Build Path
• Go to properties jfxrt.jar in Referenced Libraries
• GO to Run/Debug Settings>Css2Bin
• Mark the check box:
  • Include system libraries when searching for a main class
  • Include inherited mains when searching for a main class

Now be happy!

Answer 6

I had this same problem (in e(fx)clipse). I tried the solution mentioned above and still had the same problem. I added a new run configuration and pointed it directly to the class thar had Main and that worked for me.
