Maven手动创建.m2文件夹 IDEA
误删了系统盘用户文件夹下的 .m2文件夹或者想给.m2文件夹搬家的可以参考下。
1. 随便找个目录新建 .m2文件夹,
C盘空间不够可以随便换个盘符,不影响使用
新建文件夹的时候,windows是不支持文件命以小数点开头的,这里需要用命令行创建文件夹
2、在m2文件夹下新建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>

<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的设置
在idea中打开设置(快捷键Ctrl+Alt+S),配置第一步新建的m2目录即可(此处如果默认不是自己新建的.m2文件夹的位置,就勾选Override,重新指向新建的位置)
