JQL to search for characters in summary

[Pauline Hild]

Hi everyone,

I want to create an automation that prevents a task from being created twice by mistake. For this I need a JQL that searches for 4 characters (numbers or letters) between two underscores in the summary (e.g. _0110_), since these are contained in the summary of each project. If there is already a project that contains exactly these four characters in its summary, the creation of the task should be prevented.
How must the JQL look like for this?

Best regards,

Pauline.

Hi David,

It seems like one piece you might be missing is project categories (search the project documentation for 'category'). Yes, I think you'll want a separate projects for the different pieces of software that have different versions. Your components and versions would then be per-project.
