Maven 发布自定义jar包到Nexus中

发布命令如下：

mvn deploy:deploy-file -DgroupId=ddd.util -DartifactId=ddd-util -Dversion=1.0 -Dpackaging=jar -Dfile=C:\Users\Administrator\Desktop\dddutil.jar -Durl=http://ip:port/nexus/content/repositories/thirdparty/ -DrepositoryId=thirdparty

-DgroupId 项目
-DartifactId 模块
-Dversion 版本号
-Dpackaging是打包方式
-Dfile 架包的本地路径
-Durl 是仓库地址。
-DrepositoryId=thirdparty 是你要发布到Nexus中哪个仓库下去。
注意这儿的id是你的nexus中Repositories中对应的库中configuration中的Repository ID。如下图：


发布时报错：

解决办法
需要在maven中的conf下的setting.xml中添加：

<server>
 <id>thirdparty</id>
 <username>账号</username>
 <password>密码</password>
</server>

这儿id和发布的id一致。
再来一次就发布成功了。
