Since a successful set of Android builds on 11th May, I am encountering the following Android build error. This affects two different Macs used for building so it doesn't seem to be an environment issue. No changes to package.json etc. have been made recently.
See example demo below or from an existing project:
npm i [email protected]cd android && ./gradlew assembleReleaseBuild compiles
Build does not compile:

Download https://github.com/Microsoft/react-native-code-push/archive/master.zip and unzip. From Examples folder run node create-app.js appName [email protected] [email protected] command to generate plain CodePushified React Native app.
cd appName/android
./gradlew assembleReleaseStarted facing pretty the same issue today...Successfully build Android like a few days ago, since those time didn't do any changes to package.json. Also trying to build the app on another PC, but still review the same issue.

If someone have any suggestion, please help.
@Borovensky I also get the same single @Override failure if I try newer RN + CP.
Same here with RN version .44
This is due to https://github.com/facebook/react-native/issues/19259
Yeah, I also find the solution here: https://github.com/facebook/react-native/issues/19272
Cheers @Borovensky @ajwhite. Sorted with:
subprojects {
configurations.all {
resolutionStrategy {
force 'com.facebook.react:react-native:0.42.3'
}
}
}
Update: you don't even need the above any more because of this fix from JCenter.
@ben-snaize Thanks for update!
