配置 Maven 的 settings.xml 时，单个仓库时候都会设置 mirror 节点，例如：

  <mirrors>
    <mirror>
        <id>nexus</id>
        <mirrorOf>*</mirrorOf>
        <url>http://192.168.0.1:8061/repository/maven-public/</url>
    </mirror>
  </mirrors>

然后，增加mirror节点并不能配置多个仓库。

正确的操作是在 profiles 节点下配置多个 profile，而且配置之后要激活。例如：

<?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">
  <localRepository>C:\Users\Administrator\.m2\repository</localRepository>
  <pluginGroups>
  </pluginGroups>

  <proxies>
  </proxies>

  <servers>
  </servers>
<!--
  <mirrors>
    <mirror>
        <id>nexus</id>
        <mirrorOf>*</mirrorOf>
        <url>http://106.14.80.25:8061/repository/maven-public/</url>
    </mirror>
  </mirrors>
-->
	<profile>
		<profile> 
		  <id>aliyun</id>  
		  <repositories> 
			<repository> 
			  <id>aliyun</id>  
			  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
			  <releases> 
				<enabled>true</enabled> 
			  </releases>  
			  <snapshots> 
				<enabled>true</enabled>  
				<updatePolicy>always</updatePolicy> 
			  </snapshots> 
			</repository> 
		  </repositories> 
		</profile>
		<profile> 
		  <id>maven-central</id>  
		  <repositories> 
			<repository> 
			  <id>maven-central</id>  
			  <url>http://central.maven.org/maven2/</url>  
			  <releases> 
				<enabled>true</enabled> 
			  </releases>  
			  <snapshots> 
				<enabled>true</enabled>  
				<updatePolicy>always</updatePolicy> 
			  </snapshots> 
			</repository> 
		  </repositories> 
		</profile> 
		<profile> 
		  <id>custom-maven</id>  
		  <repositories> 
			<repository> 
			  <id>custom-maven</id>  
			  <url>http://central.maven.org/maven2/</url>  
			  <releases> 
				<enabled>true</enabled> 
			  </releases>  
			  <snapshots> 
				<enabled>true</enabled>  
				<updatePolicy>always</updatePolicy> 
			  </snapshots> 
			</repository> 
		  </repositories> 
		</profile> 
	</profile> 
	<activeProfiles>
		<activeProfile>aliyun</activeProfile>
		<activeProfile>maven-central</activeProfile>
		<activeProfile>custom-maven</activeProfile>
	</activeProfiles>
</settings>

通过配置 activeProfiles 子节点激活

<activeProfiles>
	<activeProfile>boundlessgeo</activeProfile>
	<activeProfile>aliyun</activeProfile>
	<activeProfile>maven-central</activeProfile>
</activeProfiles>

在IntelliJ IDEA或Eclipse中更新配置文件，以生效。

菜单栏Window——Preferencecs——Maven——User Setting–update Settings applyandclose

然后 maven updateproject。
