I've just confirmed this. It's a bug in maven. When you specify filtering
on resources, you NEED to have a filter file. The filter file may be
empty, but it has to be defined and has to exist for maven to filter
resources - even system properties (${user.home}) and commandline
properties (-Dx=y) won't get filtered unless you have a filter file.
So, it's not a bug in the book, but in maven. It might have worked in
pre-2.0.4 releases, though.
I'll file a JIRA issue.
