今天拉同事最新的代碼，編譯時老是報如下錯誤：
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網站上查看，從2.1.3就沒有更新了，shit！
百度上都說把版本降回到2.1.3，這不扯蛋么，難道你以后都准備只用2.1.3了？最后還是發現找到腳本，添加jcenter庫進去，就可以從jcenter里下載了
