How to set comment author as specific user with Groovy Script

[Julia Nunes Pedrosa]

Hello everyone, 

I've installed myGroovy plugin on my Jira Data Center instance and I've been able to create awesome scripts to auto-comment issues based on specific workflow transitions.

Some of my scripts are working great, but I'm having issues when trying to set the author of a comment to an specific user used in our automations.

In my previous scripts I had successfully set the author to the Current User (When closing an issue), but now I'd like to comment on the creation of the issue, so I could not use the "Logged In" user cause it would look confusing to the reporter to create the issue and see an automated comment written by himself.

That's what I've got so far.

This one works fine, but sets the comment to the Current User:

import com.atlassian.jira.component.ComponentAccessor

final boolean dispatchEvent = true 
final String commentBody = """ Hi [~${issue.reporter.name}]Comment text here.""" 
def author = ComponentAccessor.jiraAuthenticationContext.loggedInUser 

ComponentAccessor.commentManager.create(issue, author, commentBody, dispatchEvent)

 This one isn't working. The username of the user I'm trying to set as the author of the new comment is "jira_automation":

import com.atlassian.jira.component.ComponentAccessor

final boolean dispatchEvent = true 
final String commentBody = """ Hi [~${issue.reporter.name}]Comment text here.""" 
def author = ComponentAccessor.userManager.getUserByName(jira_automation)

ComponentAccessor.commentManager.create(issue, author, commentBody, dispatchEvent)

Try surrounding the username in quotes in the call to getUserByName(); that method expects a String argument, so by not surrounding it in quotes, it is likely being treated as an undefined variable.
