Create Custom Listener to Know if a story is updated

Question

H..I am using Script Runner and I need to create a custom listener to know if a story issue is updated and if yes, I need to check if the description field (which is not a custom field ) is updated. I tried finding a solution but I am stuck since most of the solutions indicate in how to update a custom field..where as I dont want to update anything here and just want to know if a field is updated by someone..

also, I am confused if I have to use

import com.atlassian.jira.issue.Issue

or

import com.atlassian.jira.event.issue.IssueEventListener

class

def issue = event.issue as Issue

Please suggest a solution if possible.

No, you can not write like this.

changeItems.getAt(i).get("field") returns the name of the field. You can log the changeItems varable and have a look at its structure.

You should define your listener for the Update Issue event.

Also..how to check if a particular issue (story) is updated? Any leads on it?

Hi @Alexey Matveev. Thanks for resp. So if I have to check for a single field.i.e description field..which is not a custom field...can I write it as

log.error(changeItems.get("Description")

?
