我如何使这个Maven POM有两个配置文件，唯一区别在于mainClass程序集

Question

我希望使用以下方法构建两个程序集：

<mainClass>com.jthink.songkong.cmdline.SongKong</mainClass>

和另一个使用：

<mainClass>com.jthink.songkong.cmdline.SongKong2</mainClass>

我知道我需要使用配置文件，但到目前为止我的尝试没有任何效果，使用mvn选项运行-P并不会产生任何不同，无论我输入真实的个人资料名称还是制作起来没有效果。目前还不清楚如何做到这一点，所以我刚刚发布了我原来的POM没有尝试失败，完全替代POM会有所帮助。

根据关联问题进行更新

所以我已经创建了两个执行，每个执行都有不同的MainClass值，它没有任何区别，仍然只是创建单个songkong-4.6-jar-with-dependencies.jar与Manfest.mf中引用的第一个类文件文件。
