android studio错误执行失败的任务：app：packageAllDebugClassesForMultiDex

Question

我从昨天起就收到了这个错误，我不知道如何解决，我已经检查并尝试了我能找到的每个相似的主题，但没有解决问题，希望你能给出解决它的想法。整个错误说：

错误：

Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: com/jcraft/jsch/agentproxy/AgentProxy.class
