Question

我使用Java为我的Mac编写了一个文件复制程序。当我从Eclipse导出一个runnable .jar时，一切都很好。所以我将其捆绑为.app并运行应用程序。一切看起来很好，GUI加载，但当我告诉它从早先的同一位置复制完全相同的文件时，它只是坐在那里。没有文件被复制，但它没有显示为无响应。

我尝试复制到桌面上的新文件夹的源文件位于/ Library / Application Support / My Files下。

由于系统将我的Java应用程序视为.app而不是.jar，我是否需要向用户请求管理员权限？

当我使用sudo命令从终端运行我的应用程序时，它会输出一堆数据。

线程“AWT-EventQueue-0”中的异常java.lang.NoClassDefFoundError：org / apache / commons / io / FileUtils

我不知道如何从Jar文件创建Mac应用程序，但错误消息显示org / apache / commons / io / FileUtils不在classpath中。有没有办法在进程中的类路径中指定额外的jar以“将其捆绑为应用程序”？

Mac Java应用程序以.jar运行，但在捆绑为.app时无法正常运行
