我在 linux 主机上有一个 jenkins 服务器。我尝试使用 jenkins 仪表板中的 jenkins 管道删除一些文件。我的管道脚本如下所示：

I just want to delete old files before writing new data,but this porblem really confused me.
我只想在写入新数据之前删除旧文件，但是这个问题真的让我感到困惑。

Permission denied means you don' have the right on that folder, perhaps you are not their owner? can you run the command as root?
权限被拒绝意味着您没有该文件夹的权限，也许您不是他们的所有者？你能以root身份运行命令吗？
回答by Anand Bajpai
it is clear that Jenkins does not have rights on those files. I faced this issue once I tested jenkins by running with root user temporarily.
很明显 Jenkins 对这些文件没有权限。一旦我通过临时以 root 用户运行来测试 jenkins，我就遇到了这个问题。
Go to Jenkins Config file (Red Hat - /etc/sysconfig/jenkins), and see which user you are using to run Jenkins). File which cannot be deleted might belong to some other user.
转到 Jenkins 配置文件（Red Hat - /etc/sysconfig/jenkins），并查看您使用哪个用户来运行 Jenkins）。无法删除的文件可能属于其他用户。
Delete those files manually with appropriate user and you should be good.
使用适当的用户手动删除这些文件，您应该没问题。
