You had already been given the answer for getting the file from the workspace
http://<servername:port>/job/<jobname>/ws/filename.ext
Obviously replace stuff in <..>
with values relevant to your setup, and make sure anonymous user has access to read from workspace, else you may have to login.
The only other files you could access are those that are archived from previous job runs.
http://<servername:port>/job/<jobname>/<buildnumber>/artifact/filename.ext
Where <buildnumber>
is the build number you see in job build history, or one of the permalinks provided by Eldad (such as lastStableBuild
). But this will only have access to archived artifacts.
You cannot arbitrarily access files from Jenkin's filesystem through the web interface... it wouldn't be very secure if it did let you.
