How to fix Build failed with an exception - react-native

Question

Can someone help me with this error?
FAILURE: Build failed with an exception.
What went wrong:
Could not resolve all files for configuration ':react-native-google-signin:debugCompileClasspath'.
Could not find play-services-auth.jar (com.google.android.gms:play-services-auth:12.0.1).
Searched in the following locations:

Try to replace your android/build.gradle with this i.e in your project level gradle with this
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenLocal()
maven {url "https://maven.google.com"} //<---- this should be added and should be aboce jcenter
maven {url "$rootDir/../node_modules/react-native/android"}
jcenter()
}
}
After that clear your gradle going inside android folder from cmd/terminal
gradlew clean
Then run the react native application
