Android Proguard 构建失败：重复的 zip 条目

Question

我在组装发布时遇到此错误：

警告：处理任务时出现异常 java.io.IOException：无法写入 [/Users/tuanchauict/pw/Android/xrmovies/app/build/intermediates/transforms/proguard/prod/release/jars/3/1f /main.jar]（无法读取 [/Users/tuanchauict/pw/Android/xrmovies/app/build/intermediates/classes/prod/release(;;;;;;**.class)]（重复的 zip 条目[android/support/v7/a/a$a.class== android/support/v7/appcompat/R$attr.class])) :app:transformClassesAndResourcesWithProguardForProdRelease 失败

这是堆栈跟踪：

（代表 OP 发布）.

我已经弄清楚问题出在哪里了。我使用了一个第三方库，它以某种方式包含了支持库中的 R 类。删除它，构建工作。
