android gradle配置阿里云镜像

对单个项目生效，1.在项目中的build.gradle修改内容。

buildscript {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google/' }
        maven { url 'https://maven.aliyun.com/repository/jcenter/'}
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }        
}

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google/' }
        maven { url 'https://maven.aliyun.com/repository/jcenter/'}
    }
}

2.本地Gradle的全局属性配置文件(注意是android目录不是project目录, 是global properties而不是project properties)gradle.properties代理配置去掉
