How do you insert the current year into IntelliJ IDEA Copyright template?

Question

I'm trying to make an Apache Velocity template for MIT license in IntelliJ IDEA copyright settings. I want it to print 2015-${current_year} where the year is. Here is what I've tried to put in Settings → Copyright → Copyright Profiles → MIT → Copyright text:

#set ($current_year = $dateTool.getCurrentDate('yyyy'))
Copyright (c)  2015-${current_year}, My Name

However, it doesn't print the current year number when I generate the license header in my source files using this template, it just prints plain text ${current_year}.

How do I make it print the current year?

Answer 1

This page of the documentation explains the built-in Velocity variables for Settings → Copyright → Copyright Profiles:

Name    Type        Comment
$today  DateInfo    The current date and time.
...
DateInfo has the following properties:
year    int         The current year.

So in my case, I needed this in my template:

Copyright (c)  2015-${today.year}, My Name
