[英]Issues building a spring boot application from within a Dockerfile on Linux
I'm having difficulty building a spring boot application from within a Dockerfile on Linux.我很难从 Linux 上的 Dockerfile 中构建 spring 引导应用程序。
It works just fine on Windows.它在 Windows 上工作得很好。
I've seen other posts where folks say I should specify or remove the relativePath in the pom.xml file, but I don't think that's the issue nor did it work.我看过其他帖子,人们说我应该在 pom.xml 文件中指定或删除 relativePath,但我认为这不是问题,也不是问题。
Here's my error, followed by my code:这是我的错误,然后是我的代码:
