# open-gateway 开放接口网关 CI（仿 usermsg/service build.yml 平台链，不含部署）
# 触发：push 到 main
# 链路：clone 源码 -> maven 容器构建 jar（复用宿主 m2 缓存）-> cp 固定名 app.jar
#       -> docker build -f docker/Dockerfile -> push Nexus docker-hosted
# Nexus 凭据从宿主 prod.env 读入 job env（同机内网 CI，安全边界等同，勿回显）
# 部署：projman 注册应用（open-gateway，空 ctx，端口 10010）后走发布链 Apply 拉起
