jcenter、mavenCentral及google三个远程仓库

在天朝使用jcenter、mavenCentral及google三个远程仓库，Gradle Sync会很慢，google仓库甚至需要梯子才能访问。为了加快Gradle Sync速度，一招教你优先用 阿里云仓库服务 的仓库作为下载源。 

一劳永逸之道

将本项目的grdadle/init.d/init.gradle复制到USER_HOME/.gradle/下即可。 USER_HOME在Windows上大约为C:/Users/liyujiang/.gradle/，在Linux上大约为/home/liyujiang/.gradle/。
init.d/init.gradle内容为：

buildscript {
    repositories {
        maven{ url 'https://maven.aliyun.com/repository/public'}
        maven { url 'https://maven.aliyun.com/repositories/jcenter' }
        maven { url 'https://maven.aliyun.com/repositories/google' }
        maven { url 'https://maven.aliyun.com/repository/central' }
    }
}
    
allprojects {
    repositories {
        maven{ url 'https://maven.aliyun.com/repository/public'}
        maven { url 'https://maven.aliyun.com/repositories/jcenter' }
        maven { url 'https://maven.aliyun.com/repositories/google' }
        maven { url 'https://maven.aliyun.com/repository/central' }
        maven { url "https://jitpack.io" }
    }
}

阿里云镜像源配置

在项目根目录下的build.gradle的allprojects.repositories闭包内的最前面添加阿里云的仓库地址：

buildscript {
    repositories {
        jcenter()
        google()
    }
}

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