Maven手動創建.m2文件夾 IDEA

誤刪了系統盤用戶文件夾下的  .m2文件夾或者想給.m2文件夾搬家的可以參考下。

1. 隨便找個目錄新建 .m2文件夾，

C盤空間不夠可以隨便換個盤符，不影響使用

新建文件夾的時候，windows是不支持文件命以小數點開頭的，這里需要用命令行創建文件夾

2、在m2文件夾下新建setting.xml

<?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>
    <!-- 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>
     -->
 
    <mirror>
      <id>alimaven</id>
      <name>aliyun maven</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
 
    <mirror>
      <id>uk</id>
      <mirrorOf>central</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://uk.maven.org/maven2/</url>
    </mirror>
 
    <mirror>
      <id>CN</id>
      <name>OSChina Central</name>
      <url>http://maven.oschina.net/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
 
    <mirror>
      <id>nexus</id>
      <name>internal nexus repository</name>
      <!-- <url>http://192.168.1.100:8081/nexus/content/groups/public/</url>-->
      <url>http://repo.maven.apache.org/maven2</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
 
  </mirrors>
</settings>

　　

3.配置Idea中maven的設置

在idea中打開設置（快捷鍵Ctrl+Alt+S）,配置第一步新建的m2目錄即可（此處如果默認不是自己新建的.m2文件夾的位置，就勾選Override，重新指向新建的位置）
