我正在尝试手动链接在我的React Native项目上安装react-native-mail，但是在Android构建上构建我的应用程序时失败，并出现异常
* What went wrong:
Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
> com.android.build.api.transform.TransformException: Error while generating the main dex list:
Error while merging dex archives:
Learn how to resolve the issue at https://developer.android.com/studio/build/dependencies#duplicate_classes.
Program type already present: com.chirag.RNMail.BuildConfig
我已经尝试./gradle clean并将React-native更新为0.63.3，但是仍然收到相同的错误:(我已经检查了已安装的软件包，但是对于RNMail却什么也没有...
请帮忙。
