要将其添加到项目中，请打开项目 build.gradle 的 (Project Level) 文件，然后添加突出显示的行，如下所示：< / p>

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

<强>样本

// Top-level build file where you can add configuration options common to all sub-projects/modules.

    buildscript {

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

        }
    }

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

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

您可能在Android Studio中使用离线模式。要停用离线模式：

确保您的设备已连接到互联网。
转到文件 - ＆gt; 设置＆amp;展开构建，执行，部署 - ＆gt; Gradle - ＆gt; UNCHECK离线工作 - ＆gt;的确定
转到文件 - ＆gt;点击使缓存无效/重新启动 - ＆gt; 无效＆amp;重新启动

完成

将google() maven repo添加到您的项目中（两次出现）：

buildscript {
  repositories {
    google()
    jcenter()
  }
  dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
    classpath 'com.google.gms:google-services:3.1.1'
  }
}

allprojects {
  repositories {
    google()
    // Your other Maven Repos
  }
}
