JJB keeps your job descriptions in human readable format and job template system simplifies the configuration of Jenkins jobs.

Taking the jobs 'builder-verify-jjb', 'builder-merge' used in releng project as examples, 'builder-verify-jjb' is to verify jobs you commited, you will see verified '+1' jenkins-ci in gerrit if it succeed, 'builder-merge' is to set up a merge job and update all the JJBs. If you have some new jobs need to be run, you can set up your own job templates and add them into the project. **Documentation tracking** |
