应用程序启动方法java.lang.reflect.InvocationTargetException中的异常以及更多JavaFx错误

Question

我找不到我的错误。我想在开始游戏之前播放一段简短的视频。我试图用JavaFX做到这一点。我的代码应该是正确的，但是我不确定那些错误。我的奔跑; --module-path“ C：\ Program Files \ Java \ javafx-sdk-15 \ lib” --add-modules = javafx.controls，javafx.fxml 我很感谢每个答案

我要运行的类的测试代码：

public class Intro extends Application {


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

    @Override
    public void start(final Stage stage) throws Exception {
        stage.setTitle("Enter The Dungeon");
        Group root = new Group();

        Media media = new Media("Video/test.avi");
        MediaPlayer player = new MediaPlayer(media);
        MediaView view = new MediaView(player);
        root.getChildren().add(view);
        Scene scene = new Scene(root, 400, 400, Color.BLACK);
        stage.setScene(scene);
        stage.show();
        player.play();
    }
}
