本文将以开源的Nexus为例,演示如何将自己开发的项目部署到Nexus Repository中,解决项目发布、升级的问题。

(一)下载并安装Nexus

    Nexus只需下载war包放到tomcat服务器上便可。



(二)配置Nexus Repository


  1. 打开WEB管理界面:http://localhost:8081/nexus/index.html
  2. 点击右上角Log In进行登录,默认帐号:admin、密码:admin123
  3. 点击左侧Repositories项 -> central仓库 -> Configuration -> Download Remote Indexes=True -> Save,表示下载远程仓库的索引。
  4. 右键central仓库 -> Update Index,更新远程仓库索引到本地,这一步能够加速本地索引。


   说明:


  • 新搭建的neuxs环境只是一个空的仓库,需要手动和远程中心库进行同步,nexus默认是关闭远程索引下载,最重要的一件事情就是开启远程索引下载。 找到右边仓库列表中的三个仓库Apache Snapshots,Codehaus Snapshots和Maven Central,然后再没有仓库的configuration下把Download Remote Indexes修改为true。然后在这三个仓库上分别右键,选择Repari Index,这样Nexus就会去下载远程的索引文件。右键仓库 -> Update Index,更新远程仓库索引到本地,这一步能够加速本地索引


  • 新建公司的内部仓库,步骤为Repositories –> Add –> Hosted Repository,在页面的下半部分输入框中填入Repository ID和Repository Name即可,另外把Deployment Policy设置为Allow Redeploy


  • Nexus中仓库组的概念是Maven没有的,在Maven看来,不管你是hosted也好,proxy也好,或者group也好,对我都是一样的,我只管根据 groupId,artifactId,version等信息向你要构件。为了方便Maven的配置,Nexus能够将多个仓库,hosted或者 proxy合并成一个group,这样,Maven只需要依赖于一个group,便能使用所有该group包含的仓库的内容。


(三)在项目中配置Nexus Repository的信息


  • 项目pom文件配置distributionManagement

(四)发布到Nexus Repository


  • 项目中执行mvn deploy,成功如下所示
