Mac Java应用程序以.jar的形式运行,但未能在捆绑为.app时正常运行。应用程序

java 来源:Lgwells1 6次浏览

我使用Java为我的Mac编写了一个文件复制程序。当我从Eclipse中导出可运行的.jar时,一切都很好。所以我将它捆绑为一个.app,然后运行该应用程序。一切看起来都很好,图形用户界面加载,但是当我告诉它从早期的相同位置复制完全相同的文件时,它就在那里。没有文件被复制,但不显示为无响应。Mac Java应用程序以.jar的形式运行,但未能在捆绑为.app时正常运行。应用程序

我想要复制到我桌面上的新文件夹的源文件位于/ Library/Application Support/My Files中。

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

当我使用sudo命令从终端运行我的应用程序时,它输出一堆数据。

我不知道Mac应用程序如何从Jar文件创建,但该错误消息显示,组织/阿帕奇/公/ IO /文件实用程序不classpath。有没有一种方法可以在进程中的类路径中指定其他jar以“将其捆绑为应用程序”?
