  <password>admin123</password>
  </server>
  <server>
  <id>snapshots</id>
  <username>admin</username>
  <password>admin123</password>
  </server>

2. 配置项目的pom.xml文件(id是在server中配的id，url为仓库的url)
<distributionManagement>
  <repository>
     <id>releases</id>
       <url>http://localhost:8081/nexus/content/repositories/releases/</url>
  </repository>
  <snapshotRepository>
     <id>snapshots</id> 
       <url>http://localhost:8081/nexus/content/repositories/snapshots/</url>
