看来每个Android Studio的版本都要一个最低版本的Gradle，
- Android Studio 2.2
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip - Android Studio 2.1
distributionUrl=https\://services.gradle.org/distributions/gradle-2.12-all.zip - Android Studio 2.0
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip - Android Studio 1.5
distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip - Android Studio 1.3
distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip
Android Studio 2.3 对应的Gradle就是 3.2版本了
