Maven阿里云代理库方案

背景说明

由于国内网络限制的原因导致maven官方仓库下载速度特别慢,甚至很多依赖下载不下来，maven.aliyun.com代理了很多公共的maven仓库。使用maven.aliyun.com中的仓库地址作为下载源，速度更快更稳定。

使用指南

https://help.aliyun.com/document_detail/102512.html?spm=a2c40.aliyun_maven_repo.0.0.36183054FeuIPW

方案说明

一般情况下在mavne项目中有两种依赖

• maven构建依赖[dependency]
• maven插件依赖[plugin]

解决方案

坐标查询

Repository	Type	Policy	Path
apache snapshots	proxy	SNAPSHOT	https://maven.aliyun.com/repository/apache-snapshots
central	proxy	RELEASE	https://maven.aliyun.com/repository/central
google	proxy	RELEASE	https://maven.aliyun.com/repository/google
gradle-plugin	proxy	RELEASE	https://maven.aliyun.com/repository/gradle-plugin
jcenter	proxy	RELEASE	https://maven.aliyun.com/repository/jcenter
spring	proxy	RELEASE	https://maven.aliyun.com/repository/spring
spring-plugin	proxy	RELEASE	https://maven.aliyun.com/repository/spring-plugin
public	group	RELEASE	https://maven.aliyun.com/repository/public
releases	hosted	RELEASE	https://maven.aliyun.com/repository/releases
snapshots	hosted	SNAPSHOT	https://maven.aliyun.com/repository/snapshots
grails-core	proxy	RELEASE	https://maven.aliyun.com/repository/grails-core
mapr-public	proxy	RELEASE	https://maven.aliyun.com/repository/mapr-public

• proxy表示的是仓库代理
• hosted表示是物理上的仓库，相当于是阿里的私服

概念说明

目前在网络上主流有两种配置方案

第一种[主流]

<mirror>
  <id>alimaven</id>
  <name>aliyun maven</name>
  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
  <mirrorOf>central</mirrorOf>        
</mirror>

• 表示把阿里的私服当做中央仓库来使用
• 可以下载到阿里私服里面的相关依赖[即使没有推送到中央仓库]
• 如果现有项目或业务强依赖阿里相关的组件，建议采用此种方案

第二种

<mirror>
    <id>alimaven-central</id>
    <mirrorOf>central</mirrorOf>
    <name>aliyun central</name>
    <url>https://maven.aliyun.com/repository/central</url>
</mirror>

• 表示使用阿里对中央仓库的代理进行使用

• 可以下载到阿里推送到中央仓库相关依赖[没有推送到中央仓库的依赖无法下载]

• 如果现有项目或业务强依赖没有阿里相关的组件，建议采用此种方案

最佳实践

dependency

repositories

repositories标签的作用是: 用来配置maven项目的远程仓库。

<repositories>
    <repository>
        <id>aliyun</id>
        <url>https://maven.aliyun.com/repository/public</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

mirror

进入maven的安装目录找到settings.xml在mirrors节点下添加如下配置

    <mirror>
        <id>alimaven-central</id>
        <mirrorOf>central</mirrorOf>
        <name>aliyun central</name>
        <url>https://maven.aliyun.com/repository/central</url>
    </mirror>
    
    <mirror>
        <id>alimaven-google</id>
        <mirrorOf>google</mirrorOf>
        <name>aliyun maven google</name>
        <url>https://maven.aliyun.com/repository/google/</url>
    </mirror>

    <mirror>
        <id>alimaven-gradle-pluginr</id>
        <mirrorOf>gradle-plugin</mirrorOf>
        <name>aliyun maven gradle-plugin</name>
        <url>https://maven.aliyun.com/repository/gradle-plugin/</url>
    </mirror>

    <mirror>
        <id>alimaven-jcenter</id>
        <mirrorOf>jcenter</mirrorOf>
        <name>aliyun maven jcenter</name>
        <url>https://maven.aliyun.com/repository/jcenter/</url>
    </mirror>

    <mirror>
        <id>alimaven-spring</id>
        <mirrorOf>spring</mirrorOf>
        <name>aliyun maven spring</name>
        <url>https://maven.aliyun.com/repository/spring/</url>
    </mirror>

    <mirror>
        <id>alimaven-spring-plugin</id>
        <mirrorOf>spring-plugin</mirrorOf>
        <name>aliyun maven spring-plugin</name>
        <url>https://maven.aliyun.com/repository/spring-plugin/</url>
    </mirror>

    <mirror>
        <id>alimaven-grails-core</id>
        <mirrorOf>grails-core</mirrorOf>
        <name>aliyun maven grails-core</name>
        <url>https://maven.aliyun.com/repository/grails-core/</url>
    </mirror>

    <mirror>
        <id>alimaven-mapr-public</id>
        <mirrorOf>mapr-public</mirrorOf>
        <name>aliyun maven mapr-public</name>
        <url>https://maven.aliyun.com/repository/mapr-public/</url>
    </mirror>

jar依赖从阿里云下载

plugin

pluginRepository标签的作用是: 用来配置maven插件的远程仓库,找到项目的pom.xml配置，添加如下配置

<pluginRepositories>
    <pluginRepository>
        <id>alimaven-central</id>
        <name>aliyun central</name>
        <url>https://maven.aliyun.com/repository/central</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
    <pluginRepository>
        <id>alimaven-jcenter</id>
        <name>aliyun jcenter</name>
        <url>https://maven.aliyun.com/repository/jcenter</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
    <pluginRepository>
        <id>alimaven-spring</id>
        <name>aliyun spring</name>
        <url>https://maven.aliyun.com/repository/spring</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>
