Automation rule for sub-task status transition

[Mohajit Acharya]

I am looking for an automation rule for the below use case:

I need to prevent the transition of a sub-task to Done if the sub-task does not have any attachment or the comment does not have a URL i.e. "https://www."

Hi @Mohajit Acharya

You will need a workflow validator. Out of the box you will not be able to meet both requirements.  You may want to use plugins such as jmwe or jsu to accomplish this.

Also instead of the url in the comment, you may want to use a url custom field and ensure that is not empty.

Thank you, Fabian.

Can we not do it using Jira Automation Rule?

I could finally get the solution using Jira Automation rules. No plugin etc. Please find attached the screenshot. Although it may not be a clean solution as far as performance is concerned but functionally wise it is serving the requirement.
