Groovy template Template is a templating engine for JavaScript. It lets you insert dynamic content in into any text through the use of templates. A template contains variables and/or expressions, which get replaced with values when a template is rendered. This is very similar to JSP markup.

Groovy templates in JMWE are used in:

• Comment issue and Comment linked related issues post-function to create the body of the comment by selecting Groovy template as the Comment type
• Create/Clone issue(s) post-function to:
  • Set fields of the new issue by selecting Groovy template as the Value type and  
  • Add a comment to the current issue by selecting Groovy template as the Comment type
• Set field value to a constant or Groovy expression and Set field value of linked related issues post-functions to set a field value by selecting Groovy template as the Value type
• Email issue post-function to write the Subject, HTML body and Text body
• Link issues to the current issue post-function to write write the JQL search expression

Groovy templating features

To output the result of a simple Groovy codeexpression, write your Groovy code as <%= some Groovy code %>. For example:

<%= issue.getKey() %>

For single-statement expressions, you can also use the following shortcut:

${issue.getKey()}

To simply execute a Groovy code and not output the result, write your Groovy code as <% some Groovy code %>. For example:

<% issuelog.getKey(debug("I was here") %>

You could also use $some Groovy code, but only for a variable and not when a method is called on a variablecan also output the value of a variable or its properties using $variable or $variable.someProperty. For example:

$currentUser() returns  returns an ApplicationUser

$currentUser.name returns the name username of the ApplicationUser$currentUsercurrent user

To call a method on the variable, use ${variable.method()}:

${currentUser.getName() returns an error} also returns the username of the current user

Groovy template examples

Write the issue key as a comment to the issue:

Issue key: <%= ${issue.get("issuekey") %>}

Comment an issue based on the priority of the issue:

<% if (issue.get("priority").name == "Critical") { %>
The priority of the issue is <%=issue.get("priority").name %>. So Look out!
<% } %>

To send an Email to the Voters and Watchers of the issue when the issue is resolved, write this as the Subject of the Email (note that we mixed <%= %> and ${} expressions only to show how both are valid):

Hi All,
<% if (issue.assignee)
{%>
The issue <%= issue.key%> has been resolved by <%=issue.assignee.assignee%>displayName%>
<%}
else
{%>
The issue <%= ${issue.key%>key} has been resolved
<%}%>
Regards,
<%=issue.get("project")?.getLead()?.getDisplayName()%>

 Note that you can also "print" to the text: If you would like to print the components of the project:

<% issue.getAvailableOptions("components").each() {
  print "Component: "+ it.name + "\n"
}
%>
