Build time: 2015-02-16 05:09:33 UTC

Build number: none

JVM: 1.8.0_40 (Oracle Corporation 25.40-b25)

可是在项目的 build.gradle 里 输入

println("I'm now compiling with gradle " + project.gradle.gradleVersion);

打印的是：

I'm now compiling with gradle 2.1

在windows -> preferences ->Gradle 里的 Gradle User Home(.gradle folder location) 自定义 gradle的bin 目录（D:\gradle-2.3\lib）解决问题。
