## 错误信息 ##

> 意思是默认的远程仓库连接不上，下载不了相应的插件

[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:3.1.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-clean-plugin:jar:3.1.0: Could not transfer artifact org.apache.maven.plugins:mav

## 配置远程仓库 ##

> settings.xml 配置阿里的远程仓库，或者自己公司的企业私服  
> mirrorOf 配置成 central

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

### POM 配置第二仓库 ###

*  settings.xml 中同时配置 mirror 和 repository ，mirror 的优先级高
 *  在 pom.xml 中添加第二仓库位置，如果企业私服没有依赖，**就会去配置的第二仓库下载**  
    ，pom 配置如下：

<repositories>
        
        <repository>
            <id>maven-aliyun</id>
            <url>http://maven.aliyun.com/nexus/content/groups/public//</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>true</enabled>
                <updatePolicy>always</updatePolicy>
                <checksumPolicy>fail</checksumPolicy>
            </snapshots>
        </repository>
    </repositories>

## settings.xml 配置信息 ##
