How to create a common shared library for ScriptRunner listeners

[Luis Castillero]

I am creating several listeners within my instance which some would benefit from having a shared library of utility functions that I can use in different listeners to avoid code repetition (DRY).

I know that I could create a single script and do what's needed based on the event type, but it will be a big script and I want to keep it simple (KISS).

Is there a way of writing reusable code in the scriptrunner scripts? I know I can define shared constant values, but I am not sure about functions

I would start  thinking about a custom plugin with a listener at this point. Scriptrunner is great at what it does but writing your own plugin will help you reuse code. 

P.S : you will have to remove and add the listener every time you update the class.

Hello Danyal,

I'm relatively new to plugin development but I'd like to give this a try.

Would you be able to point me to an example custom plugin with a listener that's developed solely for the purpose of reusing existing code? We have several ScriptRunner REST endpoints that share a lot of code. 

Many thanks!

Searching further led me to this article by Alexey Matveev.

I have just skimmed through it but I feel confident that I should be able to take it from here.

Thanks anyways!
