gradle下载依赖jar包慢

引言：  
我们在Android Studio开发过程中，Gradle编译显得尤其重要。特别是我们在下载依赖架包的时候，由于国内“闭关锁国”比较严重，导致下载速度很慢，甚至提示架包找不到，如下面的日志。既然国外的不可靠，国人还是有很多具有当担的人，一如阿里。替换成阿里镜像，就可以完美解决问题。亲测有效

一 . 单个项目配置  
找到对应工程的build.gradle,在buildscript和allprojects中都添加上阿里的maven镜像

buildscript { 
        repositories { 
            maven {  url 'http://maven.aliyun.com/nexus/content/groups/public/' }
            maven {  url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
            maven {  url 'http://maven.aliyun.com/nexus/content/repositories/google' }
            maven {  url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
            google()
            jcenter()
        }
        dependencies { 
            classpath 'com.android.tools.build:gradle:3.2.1'
        }
    }

allprojects { 
        repositories { 
            maven {  url 'http://maven.aliyun.com/nexus/content/groups/public/' }
            maven {  url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
            maven {  url 'http://maven.aliyun.com/nexus/content/repositories/google' }
            maven {  url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
            google()
            jcenter()
        }
    }

2.所有项目配置  
找到C:\\Users\\xxx.gradle文件夹，一般就是系统盘C 用户下面，在里面新建一个init.gradle，把以下代码复制到文件中

allprojects{ 
        repositories { 
            def ALIYUN_REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
            def ALIYUN_JCENTER_URL = 'http://maven.aliyun.com/nexus/content/repositories/jcenter'
            all {  ArtifactRepository repo ->
                if(repo instanceof MavenArtifactRepository){ 
                    def url = repo.url.toString()
                    if (url.startsWith('https://repo1.maven.org/maven2')) { 
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                        remove repo
                    }
                    if (url.startsWith('https://jcenter.bintray.com/')) { 
                        project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                        remove repo
                    }
                }
            }
            maven { 
                    url ALIYUN_REPOSITORY_URL
                url ALIYUN_JCENTER_URL
            }
        }
    }
