生成签名 APK 时出错:重复条目:android/support/v7/util/ThreadUtil$

Error while generating signed APK: duplicate entry: android/support/v7/util/ThreadUtil$

我为此花费了无数时间,通读了大量 SO 帖子,但似乎找不到解决方案。当我生成签名的 APK 时,我不断收到

Error:Execution failed for task ':app:transformClassesWithJarMergingForRelease'.

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v7/util/ThreadUtil$BackgroundCallback.class

我已经尝试 删除不同的 JAR 以查看可能重复的内容,但无济于事。 android-support-v7-recyclerview-23.1.1.jarseemed 对我来说就像罪魁祸首,所以我删除了它并且不再收到错误。但是,相反,我的应用程序开始需要很长时间才能生成,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。

apply plugin: 'com.android.application'

    mavenCentral()
    maven(){

    }

    }

提前致谢!

太开心了!终于修好了!

我从 gradle 中删除了 'libs/android-support-v7-recyclerview-23.1.1.jar',并在 build.gradle 的 "android" 中添加了以下行。

dexOptions { 
    javaMaxHeapSize "4g" 
}

我从 this post 那里得到了答案。
