PS

1. Android Studio 2.x don't have this problem.
2. If I rename the project :@0x5e/react-native-alipay to :react-native-alipay in android/settings.gradle and android/app/build.gradle, gradle sync will success.
3. Shall we change the module name from :@username/project-name to :@username:project-name during react-native link? See this: https://docs.gradle.org/4.2/release-notes.html#path-separator-characters-in-names-are-deprecated
