我用 Scala 和 JOGL 创建了一个 OpenGL 项目，并试图使用 sbt 和 one-jar 插件将它打包成一个 .jar 文件。

.jar 的创建没有任何错误，但是当我尝试运行 .jar 时，我收到一条错误消息，指出在主 .jar 中找不到 JOGL .jar。我跑去jar tf看主罐子里的东西，我看到里面“丢失”的罐子。

“失踪”的罐子是gluegen-rt-natives-windows-amd64.jar

这是我得到的错误：

One-Jar 是不完整的，即它没有为它的 jar-in-jar 资源提供 URL 处理程序。

如果您解压缩所有 jogamp jar 和 native，则可以使用“Fat-jar”布局：

 /com/lala1/Lala1.class
 /com/lala2/Lala2.class
 /natives/<os.and.arch>/libLala1.so
 /natives/<os.and.arch>/libLala2.so

也可以使用 Eclipse 扩展的“one-jar”实现“导出 -> Java.Runnable_JAR_file -> 库处理：将所需的库打包到生成的 JAR”这个类加载器实现确实为它的 jar-in-jar 资源提供了一个 URL 处理程序.
