Hi Nick,
Have you added the right rule in your checkstylexml? See [1]
You have right, I was missing that.
So I add in my checkstyle.xml file :
<module name="RegexpHeader">
<property name="headerFile" value="${checkstyle.header.file}"/>
</module>
But unfortunately it's still not working (no errors).
I also try to add (as for myfaces project [1]) :
<!-- Checks for Headers -->
<!-- See http://checkstyle.sf.net/config_header.html -->
<module name="Header">
<property name="headerFile" value="${checkstyle.header.file}"/>
</module>
But it's not working also.
It seems that I am missing something else.
