Answer 1

If you're opening an existing project using Android Studio 3.0 Preview 1 or later, follow the prompts to automatically update your project to the latest version of the Android plugin. To manually update your project, include the maven repo and change the plugin version in your project-level build.gradle file as follows:

打开您的项目级别 build.gradle 部分。

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

示例

 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' }
        }
    }
