Gradle failed to resolve com.google.android.gms:play-services-auth:11.6.0 [duplicate]

Answer 1

I had the same issue and I was able to resolve it by adding maven { url "https://maven.google.com" } to list of repositories in project level build.gradle as shown below.

allprojects {
    repositories {
        jcenter()
        maven { url "https://maven.google.com" }
    }
}

Also, ensure this apply plugin: 'com.google.gms.google-services' comes after your dependencies to avoid version issues.
