互換性のないライブラリのバージョンのため、Androidビルドの実行に失敗しました

Question

firebaseを使用してGoogleにサインインします。

このi>は

Error:Execution failed for task ':app:processDebugGoogleServices'. Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 9.0.0.

のようなエラーを取得しています構築する際、私のプロジェクトレベルのbuild.gradle

buildscript { 

    repositories { 
     google() 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:3.0.1' 
     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 { 
     google() 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

これは私のアプリケーション・レベルのbuild.gradle

apply plugin: 'com.android.application' 
apply plugin: 'com.google.gms.google-services' 
android { 
    compileSdkVersion 26 
    defaultConfig { 
     applicationId "wallet.mycoin" 
     minSdkVersion 16 
     targetSdkVersion 26 
     versionCode 1 
     versionName "0.2" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    implementation fileTree(dir: 'libs', include: ['*.jar']) 
    implementation 'com.android.support:appcompat-v7:26.1.0' 
    implementation 'com.android.support.constraint:constraint-layout:1.0.2' 
    implementation 'com.android.support:design:26.1.0' 
    compile 'com.google.code.gson:gson:2.8.2' 
    compile 'com.squareup.retrofit:retrofit:1.9.0' 
    compile 'com.squareup.okhttp:okhttp:2.4.0' 
    compile 'com.squareup.okio:okio:1.5.0' 
    compile 'com.squareup.okhttp:okhttp-urlconnection:2.4.0' 
    compile 'com.google.firebase:firebase-auth:11.8.0' 
    compile 'com.google.android.gms:play-services-auth:11.8.0' 
} 

です< <

そして

All firebase/gms libraries must use the exact same specification (mixing versions can lead to run time crashes) Found versions 9.0.0 and 11.8.0. Examples include com.google.firebase:firebase-analytics:9.0.0 and com.google.android.gms:play-services-auth:11.8.0.

There are some combinations of libraries , or tools and libraries that are incompatible, or can lead to bugs. One such incompatibility compiling with a version of Android support library that is not the latest version (or in a particular version lower than targetSdkVersion)

プロジェクトに追加何firebase分析ライブラリがありません。誰もが解決策を提案することができます。ビルドに失敗しました。
