Re: [Wrapper-user] How set owner/group on log file

[Maxime A. <max...@ta...>]

Thank you for your reply.

Unfortunately it is not possible to change the group of the log file
without having the root/sudo permission.
So this is not possible when the Wrapper is running with the jenkins user.

You will have to edit the ownership of your file with a linux command or
manually, using the root user.

Best Regards,

Maxime
