react-native link causes duplicate imports in Android settings.gradle

Question

For some reason when I call react-native link, it adds duplicate includes to android/settings.gradle which in turn adds duplicate imports to

Answer 1

This is a known bug on React Native. There's currently a PR pending for this bug: https://github.com/facebook/react-native/pull/18131

Update: The bug has been fixed!

To address this issue, you'll just have to manually comb through your dependencies whenever you run react-native-link. I find it's helpful to have a clean git status before running it, then going over the changed files afterwards with git diff afterwards.

CAUTION: Before executing below steps please take a backup of your project.

If i would have face this kind of problem then i would have deleted all the dependency from the settings.graddle except the include ':app', from getpackages except the new MainReactPackage() and from the app/build.graddle i would have removed all dependencies except the:

dependencies {
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"
} 

After removing all the above code i would have ran react-native link.
