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

http://blog.csdn.net/happyteafriends/article/details/8174110

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，

[html] view plain copyprint?

1.   <server>  
2.     <id>releases</id>  
3.     <username>admin</username>  
4.     <password>admin123</password>  
5.   </server>  
6.  <server>  
7.   <id>snapshots</id>  
8.   <username>admin</username>  
9.   <password>admin123</password>  
10.   </server>  
11. </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：

[html] view plain copyprint?

1. <!-- 配置远程发布到私服，mvn deploy -->  
2.     <distributionManagement>  
3.         <repository>  
4.             <id>releases</id>  
5.             <name>Nexus Release Repository</name>  
6.             <url>http://10.1.81.199:8081/nexus/content/repositories/releases/</url>  
7.         </repository>  
8.         <snapshotRepository>  
9.             <id>snapshots</id>  
10.             <name>Nexus Snapshot Repository</name>  
11.             <url>http://10.1.81.199:8081/nexus/content/repositories/snapshots/</url>  
12.         </snapshotRepository>  
13.     </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
