如果您使用Android Studio 3.0 Preview 1或更高版本打开现有项目,请按照提示自动将项目更新为最新版本的Android插件.要手动更新项目,请包含maven repo并在项目级build.gradle文件中更改插件版本,如下所示:

打开你的Project level build.gradle部分.

你应该添加maven { url 'https://maven.google.com' }.

例

 buildscript {
        repositories {
            jcenter()
             // You need to add the following repository to download the new plugin.
             maven { url 'https://maven.google.com' }
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.0.0-alpha4' // Same for alpha6

        }
    }

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