Discord Bot Java (Maven) 找不到库，加载失败 (com.sedmelluq / lavaplayer)

Question

我用 Java (Eclipse) 编写了一个 Discord 机器人程序。如果我在 Eclipse 中通过控制台启动它，它可以正常工作。如果我将它导出为“可运行的 JAR 文件”并使用 start.bat 文件启动它，它也可以正常工作。

start.bat:

java -jar NameOfTheFile.jar
pause

但是，我不想让我的电脑一直开着。一个朋友不会有这个问题，所以这个机器人在他的电脑上运行。如果 bot 由 start.bat 文件启动，则不会出现错误消息并且可以正常工作。但是，如果要播放音乐（由 !play 在语音通道中通过机器人触发），则会出现找不到库（播放音乐所需）的错误...

我有 Windows 10 + openjdk 版本“11.0.7” 2020-04-14
朋友的电脑有Windows7+最新的Java版本

如有必要，我可以附上 pom.xml。 com.sedmelluq 或 lavaplayer 由以下依赖添加：

<dependency>
  <groupId>com.sedmelluq</groupId>
  <artifactId>lavaplayer</artifactId>
  <version>1.3.50</version>
</dependency>

为什么我的一切都适用，而另一台 PC 却不行？有人可以帮忙吗？谢谢:)

问题是我朋友的电脑是 32 位系统，音乐库可能只能在 64 位系统上运行。

Discord Bot Java (Maven) 找不到库，加载失败 (com.sedmelluq / lavaplayer)

Discord Bot Java (Maven) Library not found, loading failed (com.sedmelluq / lavaplayer)
