阿里云maven/gradle加速仓库

2019-02-01

Maven官方仓库在国内网络下的下载速度实在是让人无法忍受，利用阿里云的Maven镜像可以大大提升软件包下载速度。

修改settings.xml:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      https://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>/usr/share/maven/ref/repository</localRepository>
  <mirrors>
    <mirror>
        <!--This sends everything else to /public -->
        <id>aliyun-nexus</id>
        <mirrorOf>*</mirrorOf> 
        <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    </mirror>
    <mirror>
        <!--This is used to direct the public snapshots repo in the 
            profile below over to a different nexus group -->
        <id>aliyun-nexus-public-snapshots</id>
        <mirrorOf>public-snapshots</mirrorOf> 
        <url>http://maven.aliyun.com/nexus/content/repositories/snapshots/</url>
      </mirror>
    </mirrors>
</settings>

gradle加速，对单个项目生效 build.gradle：

uildscript {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
                maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
    }    
}

allprojects {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven{ url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
    }
}

对所有项目生效，修改 USER_HOME/.gradle/init.gradle：

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
        }
    }
}
