Why can't I launch this simple FXML hello world application?

Question

I am currently in the process of migrating my hastily-made JavaFX application layout from Java to FXML so I can worry about the style, view, controller, and model all seperately, but I can't seem to able to run a simple hello world application.

I get the following error:

 Exception in Application start method
 java.lang.reflect.InvocationTargetException

Here is the View.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="calend.ae.Controller">

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

</VBox>

and the main class

package calend.ae;

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

public class Model extends Application {

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

    @Override
    public void start(Stage stg) throws Exception{
        Parent tabs = FXMLLoader.load(getClass().getResource("View.fxml"));
        stg.setTitle("Hello World");
        stg.setScene(new Scene(tabs, 450, 250));
        stg.show();
    }
}

You can find the entirety of the source code here. I only want to know why it doesn't run, for context here is the actual application

Here is the full stack trace:

Answer 1

using maven or ant?

If you use ant the fxml should go in the same dir where Model.java is
