Is it possible to automatically delete tasks in jira?

[Sergey]

Hi, is it possible to create automatic removal of tasks in fat? Can there be any plugin with which you can put the removal on the schedule?

"In fat" means "in bulk"? If so you can just make a JQL search that returns all the issues you want gone, then click on the "tools" cog icon on the upper right part of the screen and select "All XX issues", where XX is the amount of returned issues.

In the next screen (step 1 of 4) you can manually fine tune your selection or simply select all.

In the next screen you can select what to do those issues: edit them, move them... or in this case delete them.

Hope it helps.

I've just read de AUTOMATIC part... :P You would need to resort to a plugin for that. Jira Automation is a good option.
