将Firebase添加到项目后无法同步Gradle

Question

我正在使用android studio 3.0.1。在将Firebase添加到我的项目之一之后。同步项目gardle时出现了著名的错误。

Failed to resolve: com.google.android.gms:play-services-maps:16.1.1 Failed to resolve: com.google.firebase:firebase-core:16.1.1 Failed to resolve: com.google.android.gms:play-services-location:16.1.1

和其他与firebase相关的库。经过一番搜索，我意识到我们应该安装google play服务sdk并将google maven存储库添加到我的项目gradle存储库中。但是我已经做到了。

这是我的项目gradle代码

    buildscript {

        repositories {
           google()
           jcenter()
           maven {
              url 'https://maven.fabric.io/public'
          }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:4.0.1'
       }
    }

    allprojects {
        repositories {
           google()
           jcenter()
      }
    }

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

这是我的应用程序模块gradle

buildscript {
    repositories {
        maven { url 'https://plugins.gradle.org/m2/'}
    }
    dependencies {
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:0.8.1'
