JavaFX проект с Maven - исключение в методе запуска

Question

поэтому я создаю проект javafx, и все работало нормально, пока меня не заставили изменить его на проект maven, с которым я никогда не работал. Пожалуйста, помогите, я получаю следующую ошибку:

Вот часть кода, которая, я думаю, может быть связана с проблемой:

Main. java:

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import sample.views.login.LoginController;

import java.io.IOException;

public class Main extends Application {
public static final String WINDOW_TITLE = "Project";
public static final int WINDOW_WIDTH = 1200;
public static final int WINDOW_HEIGHT = 700;

public static Stage currentStage;

public static Scene previousScene;


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

    currentStage.setTitle(WINDOW_TITLE);
    switchScene(LoginController.RESOURCE_MAIN_PATH);
    currentStage.show();
}

public static void switchScene(String resourcePath) {
    if (currentStage.getScene() != null) {
        previousScene = currentStage.getScene();
    }

    try {
        Parent root = FXMLLoader.load(Main.class.getResource(resourcePath));
        Scene scene = new Scene(root, Main.WINDOW_WIDTH, Main.WINDOW_HEIGHT);

        currentStage.setScene(scene);
    } catch (IOException e) {
        e.printStackTrace();
    }
}
}

LoginController. java:

package sample.views.login;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.PasswordField;
import javafx.scene.control.TextField;
import sample.Controller;
import sample.Main;

public class LoginController {
    public static final String RESOURCE_MAIN_PATH = "views/login/login.fxml";
    private Label isConnected;
    @FXML
    private TextField input_login;
    @FXML
    private PasswordField input_password;
    @FXML
    private Button button_submit;

    @FXML
    private void handleSubmitAction(ActionEvent event) {
                Main.switchScene(Controller.RESOURCE_PATH);
    }
}

login.f xml:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<GridPane fx:controller="sample.views.login.LoginController" stylesheets="@login.css"

                <Label text="Login:"/>
                <TextField fx:id="input_login" styleClass="input"/>
            </VBox>

            <VBox spacing="2">
                <Label text="Hasło:"/>
                <PasswordField fx:id="input_password" styleClass="input"/>
            </VBox>
        </VBox>

        <Button text="Zaloguj" fx:id="button_submit" styleClass="button" onAction="#handleSubmitAction"/>
    </VBox>
</GridPane>
