Sometimes it's handy to be able to see the version number of the application somewhere on a page. The version number should ideally be "inserted" by Maven while it's building. I.e something like:
<div id="footer"> Version: 1.1 </div>
An easy way to do it is by adding the following 2 plugins to the build section of the POM.
The template just contains the following somewhere
<h:outputText value="Version: @VERSION_NUMBER@"/>
