maven下載下傳速度慢解決，國内鏡像！

修改${maven.home}/conf或者${user.home}/.m2檔案夾下的settings.xml檔案，在<mirrors>标簽下加入上述内容即可。如下：

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

<?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">
     <mirrors>
         <!-- 阿裡雲倉庫 -->
         <mirror>
             <id>alimaven</id>
             <mirrorOf>central</mirrorOf>
             <name>aliyun maven</name>
             <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
         </mirror>
     
         <!-- 中央倉庫1 -->
         <mirror>
             <id>repo1</id>
             <mirrorOf>central</mirrorOf>
             <name>Human Readable Name for this Mirror.</name>
             <url>http://repo1.maven.org/maven2/</url>
         </mirror>
     
         <!-- 中央倉庫2 -->
         <mirror>
             <id>repo2</id>
             <mirrorOf>central</mirrorOf>
             <name>Human Readable Name for this Mirror.</name>
             <url>http://repo2.maven.org/maven2/</url>
         </mirror>
     </mirrors> 
</settings>
           

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

以上選擇任意一種鏡像即可。
