title: Failed to resolve google auth dependency
body: <p>I am attempting to follow the instructions at <a href="https://developers.google.com/identity/sign-in/android/start-integrating" rel="nofollow noreferrer">https://developers.google.com/identity/sign-in/android/start-integrating</a>
  to create a Google sign in button for my application. However, when I try to use</p>
  
  <pre><code>compile 'com.google.android.gms:play-services-auth:11.6.2'
  </code></pre>
  
  <p>I get the error "Could not find com.google.android.gms:play-services-auth:11.6.2". I have followed the advice of similar questions and have made sure that my SDK is up to date but no luck.</p>
  
  <p>The project build:</p>
  
  <pre><code>buildscript {
  repositories {
      jcenter()
      mavenCentral()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:2.3.3'
      classpath 'com.google.gms:google-services:3.1.0'
      // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
  }
  }
  allprojects {
      repositories {
          jcenter()
          maven { url "https://jitpack.io" }
          maven { url "https://maven.google.com" }
      }
  }
  </code></pre>
  
  <p>And the app build:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  apply plugin: 'com.google.gms.google-services'
  
  android {
      compileSdkVersion 25
      buildToolsVersion "25.0.0"
      defaultConfig {
          applicationId "theproject.theapp"
          minSdkVersion 19
          targetSdkVersion 25
          versionCode 1
          versionName "1.0"
          testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
      }
      buildTypes {
          release {

              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
          exclude group: 'com.android.support', module: 'support-annotations'
      })
      compile 'com.android.support:appcompat-v7:25.3.1'
      compile 'com.android.support:design:25.3.1'
      compile 'com.android.support:cardview-v7:25.3.1'
  
      compile 'com.google.android.gms:play-services-auth:11.6.2'
      compile 'com.google.android.gms:play-services-maps:9.0.0'
      compile 'com.google.maps:google-maps-services:0.1.20'
  
      compile 'com.lorentzos.swipecards:library:1.0.9'
      compile 'com.squareup.picasso:picasso:2.5.2'
      compile 'com.makeramen:roundedimageview:2.3.0'
  
      compile 'com.facebook.android:facebook-login:[4,5)'
  
      testCompile 'junit:junit:4.12'
  }

  <p>Any suggestions? Thanks,</p>
