JavaFX Program isnt working when trying to compile with FXML-File

Question

so I dug into JavaFX for the last few days while following a tutorial https://www.youtube.com/watch?v=FLkOX4Eez6o&list=PL6gx4Cwl9DGBzfXLWLSYVy8EbTdpGbUIG. Now my problem is, that I cant run a project with a .fxml file in it. My code: Main:

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

   @Override
   public void start(Stage primaryStage) throws Exception{
      Parent root = FXMLLoader.load(getClass().getResource("/main.fxml"));
      primaryStage.setTitle("Hello World");
      primaryStage.setScene(new Scene(root, 300, 275));
      primaryStage.show();
   }


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

Controller:

package main.java.research;
import javafx.scene.control.Button;
public class Controller {

   public void handleButtonClick(){
       System.out.println("Run code in console");

   }
}

FXML-File:

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<VBox prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8"xmlns:fx="http://javafx.com/fxml"
  fx:controller="main.java.research.Controller">

    <Label text="I love bacon"/>
    <Button text="Submit"/>

</VBox>

I researched the problem and stumbled across an thread that had a simular problem (JavaFX InvocationTargetException). I used the solution on my project but still got the problems I had before. Now I need some new ideas on how to fix that, since I have no idea what to do. I use InteliJ Community Edition and JavaFX 14. I would not rule out an installation error.

Do you have any ideas on how to fix it?

JavaFX11+ is modular Look at "modular java" and how to use the module-info.java to export javaFX modules to your project: [releated thread](https://stackoverflow.com/questions/51843208/running-javafx-sample-on-jdk-11-with-openjfx-11-jmods-on-module-path) Also a videos tutorial of it: https://www.youtube.com/watch?v=WtOgoomDewo . Alternatively you can use gradle to export the required Modules to your project. — Luxusproblem, Apr 12 '20 at 11:32
Your problem is different to the one in the question linked by you. Hint: Starting to read the "Caused by" parts of the stacktrace from the bottom is usually a good idea, since those parts are closest to the root cause. In this case the xml parser fails to read the fxml, since the ` — fabian, Apr 12 '20 at 13:35
