To whom it may concern,
I have recently set up a Jenkins instance running on CentOS 7. I have also
mounted a Windows Share to this box and am able to read and write to it. I
have then configured the “Build Record Root Directory” parameter to use the
mounted Windows Share (/mnt/qsrfs/builds/Jenkins/${ITEM_FULLNAME}).
The issue I am having is that for every build that rights to this location
it firstly creates a time-stamped directory and then attempts to create a
symbolic link between the build number and the time-stamped directory. This
results in the builds reporting the following error:

Note however that this does not cause the build to fail (thank goodness). I
have tried to rectify this by specifying the -Dhudson.Util.noSymLink=true
and -Dhudson.Util.symlinkEscapeHatch=true in the JENKINS_JAVA_OPTIONS
variable in /etc/sysconfig/Jenkins and have restarted the Jenkins daemon
but subsequent builds still report this error. Oddly enough though if you
query System Information in Jenkins I see these settings under System
Properties.
So I have two questions about this issue:
1. Is it possible to alter the behaviour of Jenkins when creating
symbolic links, or perhaps ask Jenkins to not create symbolic links?
2. Are there any samba/cifs options that I need to specify to stop
these errors from occurring?
