JavaFX not launching

Mataske :

I'm trying to launch up a project in JavaFX and am pretty lost at what I'm doing wrong.

The Main

package Software1C482;

/*
 * This program is explicitly for the use of Western Governers University's 
 * Software 1 submission by Andrew Whited.
 */


import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;
import ViewController.HomeWindowController;

/**
 *
 * @author Andrew Whited
 */
public class InventorySystem extends Application {
    private AnchorPane MainScreenView;
    private FXMLLoader viewLoader;

    public void initMainScreen(Stage window) throws IOException{

        viewLoader = new FXMLLoader();
        viewLoader.setLocation(InventorySystem.class.getResource("/ViewController/HomeWindow.fxml"));
        MainScreenView = viewLoader.load();

        Scene scene = new Scene(MainScreenView);

        window.setScene(scene);
        window.show();
    }

    public void showMainScreen() throws IOException{
        HomeWindowController controller = viewLoader.getController();
        controller.setMainApp(this);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        primaryStage.setTitle("Inventory Mangement System"); 
        initMainScreen(primaryStage);
        showMainScreen();

    }

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

The correlated files are as following.

As said before, this question has been rewritten to better address the new problem. I'm still very new, so this may be pretty poor for a reprex.

Mataske :

I found the error. It was that I didn't include the package in HomeWindow's FXML when linking to it's controller.
