Maven配置阿里云仓库下载依赖

大家好，欢迎来到IT知识分享网。

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".
