How to get list of all Jira project admins from all jira projects ?

[Lokesh]

Is there a way to get a list of all JIRA project admins from all JIRA projects ?

This is required for our users to see that list & approach their desired project's admins for gaining access to it.

Hopefully if it could show up in a JIRA itself by clicking a link could help users for self-help

Anyone has any thoughts ?

Assuming that what you are describing as "JIRA Project admins" are the users that have the "Administer Project" permission, then you can retrieve it by utilizing the JIRA REST API and query all the projects and the "Role" members.

You can write a scripted custom field with script runner to show that, or if you want to show this not in the issue view but somewhere else you can use one of the new features of script runner which allows you to add items on various UI places and show it there.

If you have confluence or some other web publishing tool you could keep this information on a web page and link to it from a dashboard gadget.

There is no default functionality to do it. You will need to write a plugin to expose those details to users.
