You can manually delete jobs from the Completed tab of the Jobs module.
You can manually delete one or more jobs from this list. When you do this, the system launches a purge job based on the class of each run; the process is the same as if an automatic deletion had been triggered by the class properties. The system deletes only the data specified for jobs of that class. See About Classes for more information on class properties.
To delete jobs:
Select the
page to display the completed run list.Click one or more check boxes on the right end of the table to select builds for deletion.
From the list box at the bottom of the list, select the Purge option.
Click the Go button.
If the class is set to delete output files but retain console data, then deleting the run from the Completed list deletes the output files and moves the job's entry from the Completed list to the Archived list.
