UnsupportedMethodException Unsupported method: AndroidProject.getPluginGeneration().

將Android Studio升級到最新版本後，沒有升級build-tools，無法使用instant run功能，導致運行項目時，報這個錯：

UnsupportedMethodException
         Unsupported method: AndroidProject.getPluginGeneration().
         The version of Gradle you connect to does not support that method.
         To resolve the problem you can change/upgrade the target version of Gradle you connect to.
         Alternatively, you can ignore this exception and read other information from the model.

解決的方法：

方法1、可以關掉instant run功能

File--Settings--Build, Execution, Deployment--Instant Run

去掉打勾：Enable Instant Run to hot swap code/resource changes on deploy(default enabled)

方法2、可以升級build-tools；

打開SDK Manager進行更新
