Specify a separate location for settings.xml in Jenkins

Actually -s flag works. We use it maven jobs.

Under Build section add Invoke top level Maven targets and set Goals to [your goals] -s [path/to/settings.xml] (e.g. clean deploy -s /some/path/settings.xml)

I found an easy way to do this..

Go to the 'Build' Section of the job and click "Advanced". There is a 'Settings File' option there. Specify the location your 'settings.xml' file.
