When you add this post-function to a transition and trigger it, the add-on picks the value from the Comment text field and adds it as a comment on the issue. The value can be either a:
Text or Groovy template: A fixed text that can include a Groovy template markup that can be used as the comment body. For example, The issue will be resolved on or before <%= issue.duedate%> by <%issue.assignee%>.
Groovy Expression: A Groovy expressionwhose return value (of type String) will be used as the comment body. For example, issue.get("description") will add the description of the issue to the issue as a comment.
See the Expected Value tab of the Groovy help editor or refer to the documentation to know more about the expected value in the above cases.
Send "Issue Commented" notification
You can notify the users when a comment is added on the issue by selecting the option Send "Issue Commented" notification.
Run as user
Any user specified in this field will be the author of the comments that are created by the post-function. Leave it blank for the current user to be the author.
Restrict to Group
Restricts the visibility of the comment to a specified group. When you input a valid group name in the Restrict to Group field, the comment will be visible only to the members of the specified group. For no restriction, leave the field blank.
Restrict to Project Role
Restricts the visibility of the comment to a selected project role. When you select a project role from the drop-down Restrict to Project Role field, the comment will be visible only to the members of the selected project role. For no restriction, leave the field blank.
Restrict to Internal (Jira Service Desk only) - REQUIRES option "Send 'Issue Commented' notification"
Restricts the visibility of the comment to the Service Desk Agents and Collaborators only. This requires the option Send "Issue Commented" notification to be selected.
By default, all errors (Java Exceptions) raised by this post-function, including those raised by custom Groovy scripts, will be logged in the JIRA log file but will not be reported to the user and will not prevent the transition from completing. However, when designing new workflows or troubleshooting them, it is more convenient to be notified immediately of any such error during the execution of the transition. For example on the production Jira instances you might want to show errors only for the post-function(s) being worked on, in order to avoid disrupting other workflows. To make errors raised by the current post-function prevent the transition from completing and show the error in the browser, select Make transition fail when an error occurs in this post-function.
If you want to show all the errors, either only to the admins or to all users, configure the option globally on the JMWE configuration page. For example, on development and staging Jira instances, you can activate error reporting for all JMWE post-functions, to display all the errors and it is recommended to do so, and on production Jira instances you might want to activate error reporting only to administrators so that they can be made aware of configuration errors.
