maven deploy到nexus报错：Return code is: 401, ReasonPhrase:Unauthorized

提交到nexus时候报错：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project *: Failed to deploy artifacts: Could not transfer artifact *:jar:1.0 from/to releases (http://10.1.81.199:8081/nexus/content/repositories/releases/): Failed to transfer file: http://10.1.81.199:8081/nexus/content/repositories/releases/com/cs2c/security-management-client* /1.0/*-1.0.jar. Return code is: 401, ReasonPhrase:Unauthorized.

原来是没有配置认证。

maven目录conf的setting.xml里，

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

用户名和密码都是nexus的。再次deploy即可。

注意这里的id要和pom.xml里远程deploy的地址对应一致，我的pom.xml里配置：

 <!-- 配置远程发布到私服，mvn deploy -->
     <distributionManagement>
         <repository>
             <id>releases</id>
             <name>Nexus Release Repository</name>
             <url>http://10.1.81.199:8081/nexus/content/repositories/releases/</url>
         </repository>
         <snapshotRepository>
             <id>snapshots</id>
             <name>Nexus Snapshot Repository</name>
             <url>http://10.1.81.199:8081/nexus/content/repositories/snapshots/</url>
         </snapshotRepository>
     </distributionManagement>

如果这里不配置，会报错：

报错：Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.5:deploy (default-deploy) on project git-demo: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter

完整发布jar包到远程私服：

mvn deploy:deploy-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.1.0 -Dpackaging=jar -Dfile=E:\jars\ojdbc6-11.2.0.1.0.jar -Durl=http://192.168.1.176:8082/nexus/content/repositories/releases/ -DrepositoryId=releases


http://192.168.1.176:8082/nexus/content/groups/public/
-- DgroupId和DartifactId构成了该jar包在pom.xml的坐标， 对应依赖的DgroupId和DartifactId
-- Dfile表示需要上传的jar包的绝对路径
-- Durl私服上仓库的url精确地址(打开nexus左侧repositories菜单，可以看到该路径)
-- DrepositoryId服务器的表示id，在nexus的configuration可以看到
