maven中如何在setting.xml中配置多个远程仓库呢？

实现思路:
    在setting.xml的profiles标签下
	即可进行仓库的配置，如下例所示

<profiles>
<profile>
    <id>myMavenSetting</id>
    <repositories>
        <repository>
            <id>aliyun</id>
            <name>Nexus aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
            <releases>
                <enabled>true</enabled>
            </releases>
        </repository>   
        <repository>      
            <id>nexus</id>      
            <name>nexus私服URL</name>      
            <url>http://127.0.0.1:8081/repository/maven-public/</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
            <releases>
                <enabled>true</enabled>
            </releases>
        </repository>
    </repositories>
</profile>
</profiles>
<activeProfiles>
  <activeProfile>myMavenSetting</activeProfile>
</activeProfiles>
