运行javafx媒体应用程序时出现模块错误（1个答案）
上个月关门了。
我正试图在javafx应用程序中播放声音，但由于以下错误而未能播放：

我正在使用Java14和JavaFX14。我试图使用一个本地文件或传递一个uri到媒体/音频剪辑，但我总是以这个错误结束。
我尝试了一些代码片段：（所有这些代码都会导致相同的结果）

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.media.AudioClip;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Tetris");
        primaryStage.setScene(new Scene(root, 800, 600));
        primaryStage.show();
        AudioClip media = new AudioClip("https://ia800504.us.archive.org/33/items/TetrisThemeMusic/Tetris.mp3");
        media.play();
    }

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

使用mediaplayer和本地文件：

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.stage.Stage;

import java.io.File;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Tetris");
        primaryStage.setScene(new Scene(root, 800, 600));
        primaryStage.show();
        Media media = new Media(new File("Tetris.mp3").toURI().toString());
        MediaPlayer mediaPlayer = new MediaPlayer(media);
        mediaPlayer.setAutoPlay(true);
    }

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

我总是犯同样的错误，我试着加上 --add-opens javafx.graphics/com.sun.glass=ALL-UNNAMED 但是它没有改变任何东西。
