Android 使用依赖于外部JAR的库项目设置Proguard

我的android项目有很多依赖项，其中一个有一个libs文件夹和一些jar，在我尝试使用proguard之前，一切都很正常

运行proguard时，我发现此日志出错：

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proguard配置文件中添加-libraryjars标志，导致此附加警告，而不是其他警告：

Note: there were 698 duplicate class definitions.

我无法预测的库项目是ShowcaseView（com.espian.ShowcaseView）

其库的libs文件夹中的jar是：

• android-support-v4.jar
• mockito-all-1.9.5.jar
• Nineodeldroids-2.4.0.jar

我该怎么办

编辑

这是我的proguard.cfg

-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose

-keepattributes *Annotation*

# keep this class so that logging will show 'ACRA' and not a obfuscated name like 'a'.

# keep this around for some enums that ACRA needs

-keepnames class org.acra.ReportField {

# keep this otherwise it is removed by ProGuard
-keep public class org.acra.ErrorReporter

-DontskipnonPublicLibraryClass
-dontskipnonpubliclibraryclassmembers

试试这个

-libraryjars /libs/mail.jar
-libraryjars /libs/activation.jar
-libraryjars /libs/additionnal.jar

将jar文件路径写入progurd.cfg或proguard project.txt，您应该为库添加这些行。如果找不到参考类，它们将不会发出警告

-保持类com.nineolandroid.*{*；}

-dontwarn-com.nineolandroids**

我添加了我在问题中编写的完整的proguard.cfgAs，我尝试添加-libraryjars，但唯一的结果是获得了一个新的警告：注意：有698个重复的类定义。所以，我认为这不是解决办法。
