导出android项目时出现Proguard错误

Question

我试图在Eclipse中从项目（Osmand）导出android应用程序，问题是proguard返回了错误代码1.之前它抛出了多个警告，所以我用了＃34; -dontwarn＆＃34 ;命令。现在控制台就是这样：

Proguard returned with error code 1. See console
Note: there were 227 duplicate class definitions.
You should check if you need to specify additional program jars.
Unexpected error while evaluating instruction:
    Class       = [com/actionbarsherlock/app/SherlockFragmentActivity]
    Method      = [getSherlock()Lcom/actionbarsherlock/ActionBarSherlock;]
    Instruction = [10] invokestatic #36
    Exception   = [java.lang.IllegalArgumentException] (Can't find common super class     of [android/app/Activity] (with 11 known super classes) and     [com/actionbarsherlock/app/SherlockFragmentActivity] (with 6 known super classes))
Unexpected error while performing partial evaluation:

#this part was added:
-dontwarn android.support.v4.app.Watson

-dontwarn net.osmand.plus.activities.FavouritesListFragment

我该怎么办？
