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> </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)
