此问题在此处已有答案：

JavaFX MediaPlayer import（1个答案）
7个月前关闭。
最初我尝试从javafx项目创建跨平台可执行文件。一切都运行正常，所以我想在我的项目中添加音频，所以我在pom.xml中添加了javafx-media，直到我添加了javafx-media依赖性，一切都很好，但现在我得到了错误，package javafx.scene.media is not visible也不解析Media类。如何解决这个问题？
仅供参考：我使用的是：
项目：Maven
Java：JDK 13版本
IDE：网络Bean 13
Javafx：打开jfx 11
下面是我的项目结构：

如果您需要更多的说明，请告诉我。
