推荐答案

要使用 DSL implementation() 你必须使用:

To use the DSL implementation() you have to use:

• Android 3.0.0 更新的 gradle 插件
• gradle 3.4 或更高版本

然后在你的 build.gradle 你必须使用:

Then in your build.gradle you have to use:

buildscript {
    repositories {
        ...
        // You need to add the following repository to download the
        // new plugin.
        google()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta1'
    }
}

在你的 gradle-wrapper.properties

distributionUrl=
  https://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip
