Proguard：-混淆文件夹名称

我想在发布apk后混淆项目的所有文件夹名称。

我已经看到许多相关的问题，但是没有一个起作用。我试过了，-flattenpackagehierarchy 'myobfuscated'但是它创建了另一个myobfuscate文件，而不是重命名所有文件夹和类。我也用过-repackageclasses ''但找不到解决方案。请帮我。

proguard.pro文件看起来像：-

-ignorewarnings
-dontpreverify
-allowaccessmodification
-optimizations !code/simplification/arithmetic
-keepattributes *Annotation*
