I'm just a guy who started my journey as a JIRA admin almost 3 years ago, and halfway through I wanted to learn how to use JIRA API for Scriptrunner, so I've written a lot of custom scripts in the last year and a half, and I'd like to share those scripts with the Community.
I want to emphasize that I'm not a developer, and I've been learning everything by myself, so my scripts can be improved and generally written differently, so feel free to add your suggestions or improvements under a script.
To avoid stretching the post into dozens of screens, scripts will be added as comments so that further discussion can continue under a specific script.
Tip for beginners:
"I have a very hard time understanding new things and concepts, so if it worked for me, it surely will work for you too".
