How to create a Groovy expression for commeting as a post function?

For a transition I want to automatically create a comment to the issue as a post function and use information from the issue itself within the generated comment.

The following expression represents pseudo-code:

{User_how_causes_the_transition} has approved to grant {Custom_Field_ID_1234} the privilege {Custom_Field_ID_5678}.
{Assignee}: Please issue the privilege now.

 I see myself infront of the Jira "Add Parameters To Function" dialog with "Comment type" set to "Groovy Expression".

What do I have to enter into the "Value"?

I could not find a list containing what options do I have with Groovy within Jira. Ok, there is an "You can use the following variables in your Groovy script" line but how do I know what properties of the objects are available?

Hi Soren,

Assuming {User_how_causes_the_transition} is always the name of the current logged in user and {Custom_Field_ID_1234} and {Custom_Field_ID_5678} are values of respective custom fields, the code should look something like this:

import com.atlassian.jira.component.ComponentAccessor

def cfMgr = ComponentAccessor.getCustomFieldManager()

def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser().getDisplayName()
def cf1 = issue.getCustomFieldValue(cfMgr.getCustomFieldObject(1234))
def cf2 = issue.getCustomFieldValue(cfMgr.getCustomFieldObject(5678))

return "${currentUser} has approved to grant ${cf1} the privilege ${cf2}. ${issue.getAssignee().getDisplayName()}: Please issue the privilege now." as String

Thank you! I will try your snippet in a minute or so.

Do you have a reference list for "all the properties" of e.g. "ComponentAccessor" or "issue"?

I got the following error while creating an issue:

Property 'currentUser' not found

 PS: Jira version is 6.3.5

Incidentally, which addon are you using to create this post-function?

For 6.3.5 try changing 'getLoggedInUser()' to 'getUser()' in the 'currentUser' variable definition.

I am assuming Groovy post-function comments is provided by Adaptavist ScriptRunner for JIRA (, but I am not sure (just taken over the administration).

And changing it to "getUser" won't help.

The error says it could not find the property (the variable we defined). I tried to change it from "def" to "String" but this also not worked.

That's odd. Could you describe your use case more thoroughly?

Thank you for your help and sorry for the delay.


The workflow describes a permission granting process in which different transitions have different conditions on which group of users may able to use the transitions.

  1. Any user can create an issue. The reporter cannot do anything else than viewing and commenting on the issue.
  2. The issue will be automatically assigned to the responsible user (aka supervisor).
  3. The supervisor can use transitions like "approve request" or "reject request" which also requires the supervisor to enter a comment in the transition screen.
  4. No matter what the supervisor acutuall have commented and as part of the approve/reject transition, the system will add a new automatically generated comment with a "standard text" template to help further issue workers identify so called "processing comments" more easier.

Hopefully I could explain the use case your way so you can follow my thoughts ;)

Ok, let's try this again.

Create a scripted post-function on the transition which you want to generate a comment using the code below. I'm going to assume that this comment should be posted on behalf the user who triggered this transition (e.g. the supervisor?)

import com.atlassian.jira.component.ComponentAccessor

def commentMgr = ComponentAccessor.getCommentManager()
def cfMgr = ComponentAccessor.getCustomFieldManager()
def cf1Value = issue.getCustomFieldValue(cfMgr.getCustomFieldObject(1234 as Long))
def cf2Value = issue.getCustomFieldValue(cfMgr.getCustomFieldObject(5678 as Long))
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getUser()

commentMgr.create(issue, currentUser, "${currentUser.getDisplayName()} has approved to grant ${cf1Value} the privilege ${cf2Value}. ${issue.getAssignee().getDisplayName()}: Please issue the privilege now." as String, true)
