使用 Multidex 的 Android proguard

Question

我尝试在我的 android 应用程序中使用 proguard。我在我的应用程序中使用multidex，所以我在我的build.gradle 中添加了multiDexEnabled = true，但是当我尝试构建apk 时，出现以下错误：

Error:Execution failed for task 
':app:transformClassesWithMultidexlistForRelease'.
> expected one element but was: 
</Users/Amir/AndroidStudioProjects/jarchiapp/app/build/intermediates/transforms/proguard/release/jars/3/1f/butterknife-7.0.1.jar, 
/Users/Amir/AndroidStudioProjects/jarchiapp/app/build/intermediates/transforms/proguard/release/jars/3/1f/classes.jar, 
/Users/Amir/AndroidStudioProjects/jarchiapp/app/build/intermediates/transforms/proguard/release/jars/3/1f/commons-codec-1.10.jar,

/Users/Amir/AndroidStudioProjects/jarchiapp/app/build/intermediates/transforms/proguard/release/jars/3/1f/dualcache-2.2.0.jar, ...>

这是我的 proguard-rules.pro：

-libraryjars <java.home>/lib/rt.jar(javax/**)
-keepattributes *Annotation*,InnerClasses,EnclosingMethod,Signature

-keep class com.squareup.okhttp.** { *; }
-keep interface com.squareup.okhttp.** { *; }

-keep public class com.android.vending.licensing.ILicensingService
-keep class javax.** { *; }
-keep class org.** { *; }
-keep class twitter4j.** { *; }

-keepclasseswithmembernames class * {
  native <methods>;
}

-keepclasseswithmembernames class * {
   public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembernames class * {
  public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers enum * {
  public static **[] values();
  public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

问题是什么，我该如何解决？

你看过这个讨论吗？

Android support multidex library implementation

顺便说一句。我不认为这是 proguard 的问题....
