Nested If statements in jira with scriptrunner

[Louis Andrews]

Hello I am trying link issues through scriptrunner if they have matching custom fields but are two different issue types. 

For example:

If issue type "A" ID #  = issue type "B" ID #

then link issues with "has ID #"

 Issue types A & B are custom issue types

ID # is a custom issue field. 

Has ID # is a custom link 

This also can be looked at as: 

if issue type (A & B) ID # = each other

then link them with "has ID  #" 

Can someone please help me write this scriptrunner? It cannot be done with automation to my knowledge.

Hi @Louis Andrews 

I believe using switch case will be convenient, readable and a bit more manageable in future. Take a look here on how to use it in Groovy. Did you search here on the community, there are plenty of examples.
