java - 我正在尝试将 BGM 添加到我的 javaFx，但它不断抛出异常

Question

我正在使用 JavaFx 11 和 OpenJDK 15。我看过很多示例视频，但仍然出现错误。

是配置的问题吗？我的音乐文件在 src 的同一个文件夹中。任何人都可以帮忙吗？谢谢！

这是我的源代码。

    import MonopolyRPG.Controller.GameModePage;
    import javafx.application.Application;
    
    import javafx.scene.media.MediaPlayer;
    import javafx.stage.Stage;
    
    import javafx.scene.media.Media;
    
    
    public class Main extends Application {
    
        public static void main(String[] args) {
            Application.launch();
        }
    
        @Override
        public void start(Stage primaryStage) throws Exception {
            music();
            GameModePage gameModePage=  new GameModePage();
            gameModePage.start();
            primaryStage.close();
        }
    
        MediaPlayer mediaPlayer;
    
        public void music() {
            String filepath="file:///E:/MonopolyRPG-master/BGM.mp3";
            Media sound = new Media(filepath);
            //MediaPlayer mediaPlayer = new MediaPlayer(sound);
            mediaPlayer = new MediaPlayer(sound);
            mediaPlayer.setAutoPlay(true);
        }
    
    }

错误不断发生。我尝试配置VM选项并将.wav文件更改为.mp3，仍然无法意识到发生了什么。

这是正确的语法吗？
