Maven配置阿里云仓库下载依赖「建议收藏」

大家好，又见面了，我是你们的朋友全栈君。

一、前言

用过Maven的都知道Maven的方便便捷，但由于某些网络原因，访问国外的Maven仓库不便捷，maven默认使用的是国外的中央仓库，下载jar时有时候会因为网络不好等原因下载不全或失败，好在国内像阿里云、网易、JBoos、开源中国等大厂搭建了国内的maven仓库，这里阿里云的maven仓库使用的比较多。

二、配置国内Maven仓库

需要使用的话，要在maven的settings.xml 文件里配置mirrors的子节点，添加如下mirror：

<!-- 指定本地Maven仓库存储地址 -->	
<localRepository>D:\path\developTool\apache-maven\Repository\springboot_repository</localRepository>

<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>
     -->	 
	<!-- 阿里云镜像仓库地址 -->		
	<mirror>    
     <id>alimaven</id>    
     <name>aliyun maven</name>    
     <url>http://maven.aliyun.com/nexus/content/groups/public/</url>    
     <mirrorOf>central</mirrorOf> 	
    </mirror>    
	
	<!--JBoos镜像地址镜像仓库地址 -->	
	<mirror>
     <id>jboss-public-repository-group</id>
     <name>JBoss Public Repository Group</name>
     <url>http://repository.jboss.org/nexus/content/groups/public</url>
     <mirrorOf>central</mirrorOf>
    </mirror> 
		
  	<!--oschina镜像地址镜像仓库地址 -->	
	<mirror>
     <id>CN</id>
     <name>OSChina Central</name>
     <url>http://maven.oschina.net/content/groups/public/</url>
     <mirrorOf>central</mirrorOf>
    </mirror>

</mirrors>

这样，在导入新项目，或者创建项目的时候， 边可使用配置的maven仓库下载依赖，提高速度；

三、Maven的完整setting.xml配置

通过自己平常在使用Maven时总结的一些经验，下面贴出一份比较全的Maven的setting.xml配置文件提供给大家参考：

<?xml version="1.0" encoding="UTF-8"?>

<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 http://maven.apache.org/xsd/settings-1.0.0.xsd">
 
 
  <!-- 指定本地Maven仓库地址 -->
  <localRepository>D:\path\developTool\apache-maven\Repository\springboot_repository</localRepository>
 

  <!-- interactiveMode
   | This will determine whether maven prompts you when it needs input. If set to false,
   | maven will use a sensible default value, perhaps based on some other setting, for
   | the parameter in question.
   |
   | Default: true
  <interactiveMode>true</interactiveMode>
  -->

  <!-- offline
   | Determines whether maven should attempt to connect to the network when executing a build.
   | This will have an effect on artifact downloads, artifact deployment, and others.
   |
   | Default: false
  <offline>false</offline>
  -->

  <!-- pluginGroups
   | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.
   | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers
   | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.
   |-->
  <pluginGroups>
    <!-- pluginGroup
     | Specifies a further group identifier to use for plugin lookup.
    <pluginGroup>com.your.plugins</pluginGroup>
    -->
  </pluginGroups>

  <!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.
   |-->
  <proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>proxyuser</username>
      <password>proxypass</password>
      <host>proxy.host.net</host>
      <port>80</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
    -->
  </proxies>

  <!-- 私服发布的用户名密码 -->
  <servers>
    <!-- server
     | Specifies the authentication information to use when connecting to a particular server, identified by
     | a unique name within the system (referred to by the 'id' attribute below).
     |
     | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
     |       used together.
     |
    <server>
      <id>deploymentRepo</id>
      <username>repouser</username>
      <password>repopwd</password>
    </server>
    -->

    <!-- Another sample, using keys to authenticate.
    <server>
      <id>siteServer</id>
      <privateKey>/path/to/private/key</privateKey>
      <passphrase>optional; leave empty if not used.</passphrase>
    </server>
    -->
  </servers>
