点击右上角的 Log In 按钮即可登陆了。默认登录账号/密码为: admin/admin123 ,登陆成功后的界面
      
点击Repositories,将列表中所有Type为proxy 的项目的 Configuration 中的 Download Remote Indexes 设置为True
      
将Releases仓库的Deployment Policy设置为 Allow ReDeploy
      

填写完必选字段,点击Upload Artifact(s)按钮即可。

<distributionManagement>    <repository>        <id>releases</id><!--这个ID需要与你的release仓库的Repository ID一致-->        <url>http://192.168.1.11:8081/nexus/content/repositories/releases</url>    </repository>    <snapshotRepository>        <id>snapshots</id><!--这个ID需要与你的snapshots仓库的Repository ID一致-->        <url>http://192.168.1.11:8081/nexus/content/repositories/snapshots</url>    </snapshotRepository></distributionManagement> | 
修改本地$MAVEN_HOME\conf目录下的settings.xml配置文件,添加如下配置

在本地工程目录下执行:
| 
 1 
 | 
mvn deploy | 
所部署的包就自动上传到了nexus安装目录下的
      
4.配置Maven从Nexus下载构件
在POM中配置Nexus私服,这样的配置只对当前的Maven项目有效。

<!--指定Nexus的构件仓库--><repositories>    <repository>        <id>public</id>        <name>Team Maven Repository</name>        <url>http://192.168.1.11:8081/nexus/content/groups/public/</url>        <releases>            <enabled>true</enabled>        </releases>        <snapshots>            <enabled>true</enabled>        </snapshots>    </repository></repositories><!--指定Nexus的插件仓库--><pluginRepositories>    <pluginRepository>        <id>public</id>        <name>Team Maven Repository</name>        <url>http://192.168.1.11:8081/nexus/content/groups/public/</url>        <releases>            <enabled>true</enabled>        </releases>        <snapshots>            <enabled>true</enabled>        </snapshots>    </pluginRepository></pluginRepositories> | 
在settings.xml中配置profile元素,这样就能让本机所有的Maven项目都使用自己的Maven私服。
