无法生成签名的 APK - 重复条目：javax/annotation/CheckForNull.class

Question

 Error:Execution failed for task ':app:transformClassesWithJarMergingForRelease'. > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: javax/annotation/CheckForNull.class 

以下是我的应用级 gradle 文件。我尝试删除 appcompat，支持 v4，但没有帮助。该应用程序运行正常，否则只有当我尝试生成签名的 apk 时才会出现错误。

另外，有两个 CheckForNull 类，实际上在 jsr-305 中有重复的类。截图：

什么是解决这个问题的明智方法？

请使用命令./gradlew clean 对 gradle 构建进行清理。
