Android 由于响应本机邮件，Gradle生成失败

我正在尝试使用Android Studio生成已签名的APK文件，但构建失败

我得到的错误是： “错误：模块['android-RNMail'、'android react native mail']指向文件系统中的同一目录。 每个模块必须具有唯一的路径。“

这是我的android/app/build.gradle：

此外，在每次构建之后，在android/app目录中生成一个null.iml文件

我没有找到任何解决方案，只是删除了.iml文件，这根本没有帮助。 使cahces失效并重新启动也无济于事

这些问题的原因是什么？
