1通过网页上传

这种方法只是上传了jar包。通过maven引用当前jar，不能取得jar的依赖

from pom的方式，选择pom文件，以及jar。通过maven引入jar时，会自动加载jar的依赖

2通过maven的方式depoly

在maven的conf/setting.xml 配置nexus私服的管理账号

在servers标签下添加server

   <server>
      <id>nexus-snapshots</id>
      <username>repouser</username>
      <password>repopwd</password>
    </server>

id可自己定义一个名称  以及私服的管理管的账号密码

在mirrors和profiles下配置nexus私服

<mirrors>
    <mirror>
      <!--This sends everything else to /public -->
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <url>http://192.168.10.8:18080/nexus/content/repositories/releases/</url>
    </mirror>
  </mirrors>
  <profiles>
    <profile>
      <id>nexus</id>
      <!--Enable snapshots for the built in central repo to direct -->
      <!--all requests to nexus via the mirror -->
      <repositories> 
        <repository> 
            <id>nexus</id> 
            <name>local private nexus</name> 
            <url>http://192.168.10.8:18080/nexus/content/groups/public</url> 
            <releases><enabled>true</enabled><updatePolicy>always</updatePolicy>
            <checksumPolicy>warn</checksumPolicy></releases> 
            <snapshots><enabled>false</enabled></snapshots> 
        </repository>        
      </repositories> 
      <pluginRepositories> 
        <pluginRepository> 
            <id>nexus</id> 
            <name>local private nexus</name> 
            <url>http://192.168.10.8:18080/nexus/content/groups/public</url> 
            <releases><enabled>true</enabled><updatePolicy>always</updatePolicy>
            <checksumPolicy>warn</checksumPolicy></releases> 
            <snapshots><enabled>false</enabled></snapshots> 
        </pluginRepository>        
       </pluginRepositories> 
    </profile>
  </profiles>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>nexus</activeProfile>
  </activeProfiles>

在项目的pom.xml中配置

 <distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://192.168.10.8:18080/nexus/content/repositories/releases/</url>
        </repository>
        <snapshotRepository>
            <id>nexus-snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <url>http://192.168.10.8:18080/nexus/content/repositories/snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

id与settings.xml中的server的id对应

当项目package后

mvn deploy

就可以将jar上传到nexus私服
