最近在AndroidStudio命令行中使用gradle时遇到下面的错误：
java.lang.UnsupportedClassVersionError:
com/android/build/gradle/AppPlugin : Unsupported major.minor version 52.0
网上找到的答案试过之后都不行，其根本原因是编译时的jdk版本跟运行时jdk版本不一致导致的，通过gradlew命令的–info选项可以看到以下信息：
Initialized native services in: C:\Users\linkaitao.gradle\native
Found daemon DaemonInfo{pid=4512, address=[596c6783-155f-4187-bb17-3351b218c6c3 port:65257, addresses:[/127.0.

Java home is different.

很显然，是jdk版本不匹配导致的，但是更改了JAVA_HOME和IDE的jdk设置依然不行，最后将gradle.properties中加了下面一句才解决：
org.gradle.java.home=D:\Program Files\Java\jdk1.8.0_77
