带Proguard的Ksoap2

我有一个使用kso​​ap2库的应用程序，一切正常，但是从Eclipse导出应用程序时，它显示了这一点

Proguard returned with error code 1. See console
Note: there were 4 duplicate class definitions.

浏览后，ksoap2-android-assembly-3.1.1-jar-with-dependencies.jar我发现它具有自己的org.xmlpull.v1软件包，带有4个文件，自API 1起已经在android.jar中定义了。

如果ksoap的作者已经存在这些类，为什么还要添加它们呢？O_o如果他必须进行一些更改，则也可以更改包名称，这很好。

无论如何，我可以做两件事来解决这个问题。可以-dontwarn在proguard配置文件中使用。这似乎不是一个好主意。或下载源代码并删除该程序包名称并构建一个jar。

也许还有其他我可以做的事情？

谢谢
