推荐答案

您需要做的主要事情是:

The main things you need to do are:

将您的项目级别 build.gradle 文件更改为:

Change your project level build.gradle file to:

buildscript {
    repositories {
        ...
        // 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-alpha3'
    }
}

将 gradle-wrapper.properties 的 distributionUrl 更改为当前最新可用的 Gradle 版本.

Change the distributionUrl of your gradle-wrapper.properties to the currently latest available release of Gradle.

distributionUrl=https://services.gradle.org/distributions/gradle-4.0-rc-1-all.zip

在此步骤之后，您的项目还无法编译，您需要按照所有说明进行操作此处 了解如何将您的应用 build.gradle 转换为新插件
