我已多次运行此构建并且它成功运行没有任何问题。我进行了一些临时更改以构建配置并还原。从那时起它就抛出了这个错误。尝试从文件中删除所有docker命令并保留一个RUN命令。仍然存在相同的问题。它无法运行任何docker命令。

Answer 1

我遇到了同样的问题。实际上，您要查找的文件不存在于工作区作业目录中。如果您的docker-step-plugin可以找到该文件，那么来自您的Dockerfile的命令ADD将起作用:-) 希望这有帮助。

Answer 2

我知道这是相当陈旧的，但我遇到了这个问题并找到了一个不同的解决方案，可以帮助将来发现这个问题的其他人。

在我的情况下，我使用devicemapper作为存储驱动程序，并且包含thinpool的逻辑卷已经达到90％已满，此时它会在尝试创建新图像时触发警报。这导致Jenkins Docker插件失败，上面发布了相同的堆栈跟踪。

从图像存储中删除旧图像解决了问题。
