我的 android 项目有很多依赖项，其中一个有一个带有一些 jar 的 libs 文件夹，在我尝试使用 proguard 之前一切正常。
运行 proguard 时，此日志出现错误：
Warning: [!!few lines like this!!]: can't find superclass or interface [...]
Warning: [!!many lines like this!!]: can't find referenced class [...]
You should check if you need to specify additional program jars.
Warning: there were 190 unresolved references to classes or interfaces.
You may need to specify additional library jars (using '-libraryjars').
Warning: there were 6 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile them and try again.
Alternatively, you may have to specify the option
'-dontskipnonpubliclibraryclassmembers'.
java.io.IOException: Please correct the above warnings first.
然后我尝试在我的 proguard 配置文件中添加 -libraryjars 标志，导致此附加警告高于其他警告：
Note: there were 698 duplicate class definitions.
我无法保护的库项目是 ShowcaseView (com.espian.showcaseview)。
其库的 libs 文件夹中的 jars 是：
- 安卓支持-v4.jar
- mockito-all-1.9.5.jar
- Nineoldandroids-2.4.0.jar
我应该怎么办？！
编辑
这是我的 proguard.cfg
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
