You might need to just write your own plug-in to get this kind of
properties file output.

Thanks Kenney. I think what I want is similar to how the pom.propertieswould
normally be
generated by Maven. As in, I want some code / cofiguration that can
generate a properties
file with the "version" in it.
For example, I want something to work like
eg.
myApp.properties.template (with contents)
version.from.maven=${maven.pom.version}-${maven.package.build.date}
to produce:
myApp.properties (with contents)
version.from.maven=1.0-SNAPSHOT-2006-05-22
And so I can place in the myApp.properties in the class path and easily
read it?
