就像您可能知道我是一名DevOps工程师一样，要获得我的学位，我必须提交一个项目
我到了必须离线编译Maven项目的地步
我的老师强加了一个nexus存储库，我将maven的settings.xml配置为从Nexus连接和下载存储库（这是第一次从maven中央连接并下载），并与代理连接，这与Nexus服务器相同，我的问题是插件的下载，我跟随this link并将maven存储库配置程序插件放到项目中，但是当我在项目中编写命令mvn clean install时，出现503错误（屏幕截图为最后，我的目标是为项目成功编译并生成.ear，以便我可以将其部署在服务器上，在此先感谢sceenshot link pom.xml：
