After Android Studio update: Gradle DSL method not found: 'runProguard()'

1 具体报错为：

Error:(16, 0) Gradle DSL method not found: 'runProguard()'

Possible causes:<ul><li>The project 'App' may be using a version of Gradle that does not contain the method.

.

>

2  原因：从 Android Gradle Plugin 0.14.0以后，runProguard属性被更名为minifyEnabled ，可以查看gradle plugin的版本说明
