我用Java为我的Mac编写了一个文件复制程序。当我从Eclipse导出一个可运行的.jar时，一切都很好。所以我把它捆绑成一个.应用程序，然后运行这个应用程序。GUI加载后，一切看起来都很好，但当我告诉它从与前面相同的位置复制完全相同的文件时，它就在那里。没有复制任何文件，但不会显示为无响应。
我试图复制到桌面上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而非.jar，我需要向用户请求管理权限吗？
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"java.lang.NoClassDefFoundError:org/apache/commons/io/FileUtils 中出现异常
我不知道Mac应用程序是如何从Jar文件创建的，但错误消息显示org/apache/commons/io/FileUtils不在classpath中。有没有一种方法可以在进程的类路径中指定额外的jar来"将其捆绑为应用程序"？
