## **指定本地仓库** ##

### **1.建立任意一个目录存放下载下来的依赖，我的是 E:\\maven\\mvn** ###

### 2.在maven安装目录下的 apache-maven-3.6.3\\conf\\settings.xml 中添加 localRepository 标签 ###

<localRepository>E:\maven\mvn</localRepository>

## **配置阿里云镜像** ##

在maven安装目录下的 apache-maven-3.6.3\\conf\\settings.xml 中 mirrors标签下添加

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

### 完整的settings.xml 文件 ###

<?xml version="1.0" encoding="UTF-8"?>
    
    
    
    
    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

## 遇到的一些问题总结 ##

### 1.pom.xml下<groupId>org.apache.maven.plugins</groupId>报错 ###

### 解决思路 ###

1.查询IDEA的maven设置，IDEA自带的配置和自己下载的maven配置

2.为<groupId>org.apache.maven.plugins</groupId> 设置版本号，版本号在自己maven本地仓库里查看
