Changes made to email templates doesn't work

Viktor Lytvyn_0uz0iu

In our Jira instance we needed to modify Subjects for Jira notifications for several projects.
We modified files in atlassian-jira\WEB-INF\classes\templates\email\subject, and tested then on Staging instance, where they worked as intended. (for that i used this article)
But they don't work on Prod instance. Can you please help to investigate what's the problem?

The code in most of them looks something like this:

#if ($issue.Project.key == "PROJ1" || $issue.Project.key == "PROJ2" || $issue.Project.key == "PROJ3" || $issue.Project.key == "PROJ4")
#if ($issue.issueType.name == "Bug")
#set ($emailIssueType = "Bug")
#elseif ($issue.issueType.name == "Epic")
#elseif ($issue.issueType.name == "Story")
#set ($emailIssueType = "Story")
#elseif ($issue.issueType.name == "Task")
#set ($emailIssueType = "Task")
#elseif ($issue.issueType.name == "Sub-task")
#set ($emailIssueType = "Sub-T")
#else
#set ($emailIssueType = "")
#end
#if ($issue.Priority)
#set ($emailPriority = "[P" + $textutils.left($issue.Priority.name,1) + "]")
#else
#set ($emailPriority = "")
#end
#set($joinCom = "")
#foreach($com in $issue.ComponentObjects)
#set($joinCom = $joinCom + "[" + $com.name + "]")
#end
[U][$emailIssueType][$textutils.left($issue.Status.name,12)]$emailPriority $eventTypeName: ($issue.key) $issue.summary $joinCom
#else
#disable_html_escaping()
($issue.key) $issue.summary
#end

Hi @Viktor Lytvyn 

As written in the document it is not recommended to modify the vm files, these modifications have to be tracked and reapplied after future upgrades.

In case you still want to do it. Did you restart your production after making these changes. I think you have to set one property to avoid restart, check the document.

Also by any chance you have ScriptRunner for Jira? You can also use it to send custom emails.
