Maven镜像更换为阿里云中央仓库提高下载速度

简述：

• maven.aliyun.com代理了不少公共的maven仓库。使用maven.aliyun.com中的仓库地址做为下载源，速度更快更稳定。

可用仓库列表

仓库名称	代理源地址	使用地址
central	https://repo1.maven.org/maven2/	https://maven.aliyun.com/repository/central 或 https://maven.aliyun.com/nexus/content/repositories/central
jcenter	http://jcenter.bintray.com/	https://maven.aliyun.com/repository/jcenter 或 https://maven.aliyun.com/nexus/content/repositories/jcenter
public	central仓和jcenter仓的聚合仓	https://maven.aliyun.com/repository/public 或https://maven.aliyun.com/nexus/content/groups/public
google	https://maven.google.com/	https://maven.aliyun.com/repository/google 或 https://maven.aliyun.com/nexus/content/repositories/google
gradle-plugin	https://plugins.gradle.org/m2/	https://maven.aliyun.com/repository/gradle-plugin 或 https://maven.aliyun.com/nexus/content/repositories/gradle-plugin
spring	http://repo.spring.io/libs-milestone/	https://maven.aliyun.com/repository/spring 或 https://maven.aliyun.com/nexus/content/repositories/spring
spring-plugin	http://repo.spring.io/plugins-release/	https://maven.aliyun.com/repository/spring-plugin 或 https://maven.aliyun.com/nexus/content/repositories/spring-plugin
grails-core	https://repo.grails.org/grails/core	https://maven.aliyun.com/repository/grails-core 或 https://maven.aliyun.com/nexus/content/repositories/grails-core
apache snapshots	https://repository.apache.org/snapshots/	https://maven.aliyun.com/repository/apache-snapshots 或 https://maven.aliyun.com/nexus/content/repositories/apache-snapshots

使用教程

maven配置指南

1. 全局配置方式修改settings.xml

   打开maven的配置文件(windows机器通常在maven安装目录的conf/settings.xml)，在 <mirrors></mirrors> 标签中添加mirror子节点:

   <mirror>
       <id>aliyunmaven</id>
       <mirrorOf>*</mirrorOf>
       <name>阿里云公共仓库</name>
       <url>https://maven.aliyun.com/repository/public</url>
   </mirror>

   若是想使用其它代理仓库,可在 <repositories></repositories> 节点中加入对应的仓库使用地址。以使用google代理仓为例：

   <repository>
       <id>spring</id>
       <url>https://maven.aliyun.com/repository/google</url>
       <releases>
           <enabled>true</enabled>
       </releases>
       <snapshots>
           <enabled>true</enabled>
       </snapshots>
   </repository>

2. 单个项目配置方式修改pom.xml

   直接在项目的pom.xml中加入中央库的地址。以下：

   <repositories>
       <repository>
           <id>alimaven</id>
           <name>aliyun maven</name>
           <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
       </repository>
   </repositories>

gradle配置指南

在build.gradle文件中加入如下代码:

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        mavenLocal()
        mavenCentral()
    }
}

若是想使用maven.aliyun.com提供的其它代理仓，以使用spring仓为例，代码以下:

allProjects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/spring/'}
        mavenLocal()
        mavenCentral()
    }
}
