Maven - 解决Maven下载依赖包速度慢问题

2023-11-30 09:47:04

通常我们会因为下载jar包速度缓慢而苦恼，这十分影响开发效率，以及程序员的心情，在IDE下载jar时，无法对IDE做任何动作，只能大眼对小眼。

下载jar速度慢究其原因就是因为很多资源都是国外的，我们下载一个小文件几乎就跨越了一个太平洋那么远，那么有什么方法可以让下载速度变快呢？

其实方法很简单：maven是支持镜像的，我们可以在${maven_home}的conf目录下的setting.xml文件中找到<mirrors></mirrors>标签

<mirrors>  
    <!-- mirror  
     | Specifies a repository mirror site to use instead of a given repository. The repository that  
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used  
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.  
     |  
    <mirror>  
      <id>mirrorId</id>  
      <mirrorOf>repositoryId</mirrorOf>  
      <name>Human Readable Name for this Mirror.</name>  
      <url>http://my.repository.com/repo/path</url>  
    </mirror>  
     -->  
      
  </mirrors>

在这个标签中加入国内的镜像即可

这里我推荐maven阿里云*仓库

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

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

下面是一些常用的maven国内镜像

<mirror>  
      <id>CN</id>    
      <name>OSChina Central</name>                                                                                                                           
      <url>http://maven.oschina.net/content/groups/public/</url>    
      <mirrorOf>central</mirrorOf>  
    </mirror>  
    <mirror>      
          <id>repo2</id>      
          <mirrorOf>central</mirrorOf>      
          <name>Human Readable Name for this Mirror.</name>      
          <url>http://repo2.maven.org/maven2/</url>
