我一直试图让ProGuard在过去2天内运行，但是无法解决这个问题。
完整错误
java.io.IOException：无法写入[/PATH_TO_POJECT/build/intermediates/classes-proguard/release/classes.jar]（无法读取[/ PATH_TO_POJECT / build / intermediates / explosion-aar / com。 facebook.android/FaceBook320/3.20.0/libs/android-support-v13.jar(;;;;;;!META-INF/MANIFEST.MF）]（重复的zip条目[android-support-v13.jar：android /support/v13/app/FragmentCompat$ICSFragmentCompatImpl.class]））
我正在使用Android Studio。我的项目包含几个不同的模块，其中两个模块依赖于android-support-v13.jar。我确保每个模块的android-support-v13.jar都相同。
我也试过从这些模块中排除支持jar： 的的build.gradle
compile (project(':FaceBook320')){
exclude module: 'support-v13'
exclude module: 'support-v4'
}
但我仍然得到同样的错误。
我的proguard-project.pro：
-optimizationpasses 5
#When not preverifing in a case-insensitive filing system, such as Windows. Because this tool unpacks your processed jars, you should then use:
-dontusemixedcaseclassnames
#Specifies not to ignore non-public library classes. As of version 4.5, this is the default setting
-dontskipnonpubliclibraryclasses
#Preverification is irrelevant for the dex compiler and the Dalvik VM, so we can switch it off with the -dontpreverify option.
-dontpreverify
#Specifies to write out some more information during processing. If the program terminates with an exception, this option will print out the entire stack trace, instead of just the exception message.
-verbose
#The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle. Note that the Dalvik VM also can't handle aggressive overloading (of static fields).

我已经看过这个问题的每一个帖子，并尝试了所有，请帮忙！ 谢谢！
答案 0 :(得分：1)
在Gradle构建系统中，请不要直接在其jar中链接来包含支持库。 Gradle有一个更好的方法来处理这些依赖关系，这将防止你在这里看到类重复的问题。
在dependencies块中通过此语句包含support-v13依赖项：
compile 'com.android.support:support-v13:21.0.2'
根据您通过SDK管理器安装的内容，使用适当的版本号。如果您通过项目结构＆gt;添加依赖项（您的模块）＆gt;依赖性＆gt; +＆gt;库依赖，它可以帮助您正确使用它。
