一：官网
http://gradle.org/release-candidate/ http://services.gradle.org/distributions
二：android studio 设置本地目录
1. 下载gradle并解压
2. File > Settings > Build, Execution, Deployment > Gradle
勾选 Use local gradle distribution 并选择解压目录
3. 或者设置项目的gradle-wrapper.properties
文件位置 项目文件夹\gradle\wrapper\gradle-wrapper.properties
在iis增加一个虚拟目录，指向gradle的压缩文件
三：gradle的cache
File > Settings > Build, Execution, Deployment > Gradle > Service directory path
四：gradle errors
1.
修改build.gradle
classpath 'com.getkeepsafe.dexcount:dexcount-gradle-plugin:0.3.0' 改为 classpath 'com.getkeepsafe.dexcount:dexcount-gradle-plugin:0.6.2'
