配置nexus作为maven的本地代理仓库

私服介绍：

hosted：本地存储。像官方仓库一样提供本地私库功能

proxy：提供代理其它仓库的类型

group：组类型，能够组合多个仓库为一个地址提供服务

maven-central：maven中央库，默认从https://repo1.maven.org/maven2/拉取jar

maven-releases：私库打包发行版jar

maven-snapshots：私库快照（调试版本）jar

maven-public：仓库分组，把上面三个仓库组合在一起对外提供服务，在本地 maven 基础配置 settings.xml 中使用。

Hosted有三种方式：Releases、Snapshot、Mixed

Releases：一般是已经发布的Jar包

Snapshot：未发布的版本

Mixed：混合的

maven的配置：

<mirrors>
	<!--
	如果想让nexus作为maven的代理仓库就不要配置这一段了
	<mirror>
		<id>alimaven</id>
		<name>aliyun maven</name>
		<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
		<mirrorOf>central</mirrorOf>
	</mirror>
	-->
	<!-- 与上面的配置二选一，mirrorOf 为 * 表示这个镜像将替代所有的远程仓库请求 -->
	<mirror>
		<id>nexus</id>
		<mirrorOf>*</mirrorOf>
		<url>http://192.168.0.62:8081/repository/maven-central/</url>
	</mirror>
</mirrors>
