              Using Jenkins.md
            
          
    Restart jenkins

That's how we restart jenkins service.
sudo service jenkins restart
Jenkins defaults

Are stored in /etc/default/jenkins.

Example: the default port named HTTP_PORT.
Note: we need to restart after making changes:

Example
sudo nano /etc/default/jenkins
sudo service jenkins restart
Git timeout of a project

Default workspace

The default workspace is written in /etc/default/jenkins with the tag "JENKINS_HOME" mine was JENKINS_HOME=/var/lib/jenkins.
Change workspae

We can change the workspace per project through the "Advanced Project Options" section -> Use Custom Workspace option.
To change the WORKSPACE we'll need to ensure that jenkins is the owner of the workspace out of /var/lib/jenkins ... by chown to jenkins
sudo chown jenkins -R master_directory
sudo chown jenkins -R build_directory
GUI application execution

To execute any gui application we must ensure the $DISPLAY and $XAUTHORITY have the right variables and $XAUTHORITY's path is accessible by jenkins ... for me the $DISPLAY was ":0" ... and $XAUTHORITY was "/home/walid5/.Xauthority" ... which had the permission set to 600, I had to change it to 644 so that jenkins can access it
