今天拉同事最新的代码，编译时老是报如下错误：

Error:Could not find com.android.tools.build:gradle:2.2.0.
Searched in the following locations:
file:/D:/software/android-studio/gradle/m2repository/com/android/tools/build/gradle/2.2.0/gradle-2.2.0.pom
file:/D:/software/android-studio/gradle/m2repository/com/android/tools/build/gradle/2.2.0/gradle-2.2.0.jar
https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.0/gradle-2.2.0.pom
https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.0/gradle-2.2.0.jar

跑到maven.org网站上查看，从2.1.3就没有更新了，shit！

 百度上都说把版本降回到2.1.3，这不扯蛋么，难道你以后都准备只用2.1.3了？最后还是发现找到脚本，添加jcenter库进去，就可以从jcenter里下载了

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