運行我的代碼時出現 FXML 異常錯誤

Question

這是我的主要內部應用程序 package：

package application;

import java.net.URL;

import javax.swing.JOptionPane;

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


public class Main extends Application {
Parent root;
Scene scene;
@Override
public void start(Stage primaryStage) {
    try {
        URL url = getClass().getResource("/view/AddCustomer.fxml");
        root = FXMLLoader.load(url);
        scene = new Scene(root);
        primaryStage.setScene(scene);
        primaryStage.setOnCloseRequest(e -> {
            int save = JOptionPane.showConfirmDialog(null, "Do you want to save changes in the product table?");
            if (save == 0) {
                Model.getInstance().SaveCustomers();
                Model.getInstance().SaveSessions();
                Model.getInstance().SaveAdministrators();
                Model.getInstance().SaveCoachs();
            }
            System.exit(0);
        });
        primaryStage.show();
    } catch(Exception e) {
        e.printStackTrace();
    }
    
}
public static void main(String[] args) {

    launch(args);
}
}

這是我在 controller package 內的 addCustomerController：

package controller;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.RadioButton;
import javafx.scene.control.TextField;
import javafx.scene.layout.Pane;

public class AddCustomerController {

    @FXML
    private Button cancelMemberButton;

    @FXML
    private Pane customerPane;

    @FXML
    private RadioButton dailyMemberType;

    @FXML
    private TextField memberDiscountField;

    @FXML
    private RadioButton memberFemaleButton;

    @FXML
    private TextField memberIdField;

    @FXML
    private RadioButton memberMaleButton;

    @FXML
    private TextField memberMobileField;

    @FXML
    private TextField memberNameField;

    @FXML
    private TextField memberNationalityField;

    @FXML
    private RadioButton monthlyMemberType;

    @FXML
    private Button saveMemberButton;

    @FXML
    private RadioButton yearlyMemberType;

    @FXML
    void cancelButtonClick(ActionEvent event) {

    }

    @FXML
    void saveButtonClick(ActionEvent event) {

    }

}

這是視圖包中的 FXML 文件（名為 AddCustomer.fxml）：

這是我在運行 main 時遇到的錯誤：

我在網上搜索問題，我發現網上提供的所有問題至少從我的理解來看與我的不相似。 我修復了代碼中的一些內容。 但是，它仍然沒有為我解決問題。 請我需要幫助解決這個問題。

您正在從他們的移動工具中使用 Gluons com.gluonhq.charm.glisten.control.ToggleButtonGroup。 你真的想那樣做嗎？ 也許使用標准的 JavaFX ToggleGroup就足夠了。 如果你真的想使用 Gluons lib，那么你必須將這個implementation 'com.gluonhq:charm-glisten:6.2.2'添加到你的依賴項中。 但請注意，glisten 是專有產品，其許可證與 JavaFX 不同。
