Could not find com.android.tools.build:gradle

Could not find com.android.tools.build:gradle:3.0.0.

或者改代码：根目录下的build.gradle

buildscript {    repositories {        jcenter()    }    dependencies {        classpath 'com.android.tools.build:gradle:2.2.3'        // NOTE: Do not place your application dependencies here; they belong        // in the individual module build.gradle files    }}
