Environment variables in project.properties?

[Daniel Rabe]

I'd really like to be able to use environment variables in my
project.properties. For example, instead of:

cactus.home.tomcat5x = C:/Program Files/Apache Software Foundation/Tomcat
5.0

I'd like to be able to say something like this:

cactus.home.tomcat5x =${TOMCAT_HOME}

I wasn't able to find anything in the maven documentation... is there a way
to do this?

Thanks,
Daniel Rabe
