I am trying to load an FXML file into my javafx application as my root widget, I am using windows 8.1 with java 11.04 and javafx-sdk 13 with the Eclipse 2019 IDE. I searched a little bit on the internet but did not find anything. my situation is a bit complicated, because javafx is not available on java 11, so I installed it by myself which took a lot of time to figure out how to.
This is the code that I am trying to run :
package application;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;
public class Main extends Application {
@Override
public void start(Stage primaryStage) {
try {
Parent root = FXMLLoader.load(getClass().getResource("Test1.fxml"));
Scene scene = new Scene(root);
;
primaryStage.setScene(scene);
primaryStage.show();
} catch(IOException ex) {
ex.printStackTrace();
}
return ;
}
public static void main(String[] args) {
launch(args); // we could also say Application.launch(args)
System.out.println("Hello World!");
// this will launch the javafx application!
;
return ;
}
}
The fxml file that I want to load is "Test1.fxml" which in in the same directory with the Main.class .
This is the whole console output :

Exception running application application.Main
One more thing is that when I use a javafx class that is not imported, I put the cursor and it suggests several possible solutions. Two of them are : import com.sun.javafx.Instance and javafx.Instance. I don't know where com.sun.javafx did come from neither what thing did download that package. All I know is that it is not working, I only sat up the javafx.* by my hands. I installed e(fx)clipse 3.6.0 on the market place of eclipse, and downloaded the *.jar files from gluonHQ website and assigned them all as one library that I named "javafx" and added it to my current project. What I think FXMLLoader is trying to do is loading some needed packages from com.sun.WhatEver and it is returning an error while trying to import something.
since Java 11 you need to add
--module-path C:[your path to]\javafx-sdk-13\lib --add-modules javafx.controls,javafx.fxml
to the run arguments of the project run configuration
