Groovy expression input for fields

This document lists the expected result of a Groovy expression that should be provided to set Jira Standard and Custom fields. The easiest is to use the "Expected Value" tab of the Groovy editor help system. It lists the possible expected values for the selected Field and Value Type. This is applicable in contexts where you set a field value or comment an issue or write a conditional Groovy script. Select the Field and Value Type as Set field value to Groovy expression. Click on Expected Value. The help editor displays the expected values for the selected field.

You might also want to look at Standard fields, Predefined custom fields, and User-created custom fields to know how to access the fields of an issue object.
