用Java14在JavaFX中播放Media/Audioclip[副本]

Question

我试图在JavaFX应用程序中播放声音，但由于以下错误而失败：

我正在使用Java14和JavaFX14。我尝试使用本地文件或将URI传递给媒体/音频唇，但总是以这个错误结束。

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);
    }
}

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);
    }
}

我总是得到相同的错误，我尝试将--add-opens javafx.graphics/com.sun.glass=all-unnamed添加到VM参数中，但没有改变任何东西。

Answer 1

由于@jabir的注释，我在另一个stackoverflow问题中读到，我所缺少的只是在VM参数中声明的--add-modules中添加了javafx.media
