React native - assemble release apk

Question

I'm trying to assemble a release APK to test the app on another Android phone, and being blocked by following error.

> Task :app:lintVitalRelease FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:lintVitalRelease'.

Any suggestions?

Answer 1

There is currently an issue with jcenter. https://status.bintray.com/

In the meantime, try cutting your internet connection and running the assemble script.

Answer 2

Open your build.gradle file and add the code below under android:

android {

    lintOptions { 
      checkReleaseBuilds false 
 }
