Jenkins – How to set the workspace root directory on Jenkins nodes

Your understanding is correct, an artifact in the Jenkins sense is the result of a build - the intended output of the build process.

A common convention is to put the result of a build into a build, target or bin directory.

The Jenkins archiver can use globs (target/*.jar) to easily pick up the right file even if you have a unique name per build.

To restart Jenkins manually, you can use either of the following commands (by entering their URL in a browser):

(jenkins_url)/safeRestart - Allows all running jobs to complete. New jobs will remain in the queue to run after the restart is complete.

(jenkins_url)/restart - Forces a restart without waiting for builds to complete.
