生成签名的APK时出错：重复项：android / support / v7 / util / ThreadUtil $

我在此上花费了无数的时间，阅读了大量的SO帖子，但似乎找不到解决方案。当我生成签名的APK时，我不断

错误：任务'：app：transformClassesWithJarMergingForRelease'的执行失败。

com.android.build.api.transform.TransformException：java.util.zip.ZipException：重复条目：android / support / v7 / util / ThreadUtil $ BackgroundCallback.class

我尝试删除不同的JAR，以查看可能是重复的，但无济于事。android-support-v7-recyclerview-23.1.1.jar看起来像是我的罪魁祸首，所以我将其删除，再也没有收到错误。但是，相反，我的应用开始花费很长时间才能生成，CPU使用率达到350％，然后gradle超时并出现“ OutOfMemory”异常。

这是我的build.gradle文件。
