【问题描述】:
我正在尝试从我的 DockerFile 构建 Docker 映像,但不断收到错误消息,例如找不到父级 pom.xml 以在 docker 文件中执行 maven 命令并构建项目。
我一直在环顾四周,您会看到人们所做的是向子元素添加 pom.xml 对父 pom.xml 的引用,您尝试向子元素添加 relativePath>.. /pom.xml/relativePath>,但仍然无法正常工作。

我不确定发生了什么问题或如何使构建工作,感谢您的帮助。
【问题讨论】:
-
出于兴趣,您为什么希望您的容器运行 maven 构建?这可以由主机运行,您只需将
.jar复制到您的容器中 -
让它更加自动化,不必在主机上构建
-
一般来说,像 Jenkins 这样的专用构建服务器用于此类任务,生成的工件用于构建容器,但对于本地开发,您的方式可行
