java - How to specify in Maven extra source/resource folders so IDEs are aware of them?

Question

I'm a Maven beginner, and after some trial and error, I managed to specify different properties files for the release WAR with respect to the development WAR (I tried to do it in the simplest way I could think of, but feel free to suggest any simpler solution).

So, during development, my database.properties and log4j.properties come from src/main/resources, while producing the release WAR they come from src/main/resources/release.

So far, so good.

The question is: since I'm working with Eclipse, is there a way to say, inside the POM, that the src/main/resources/release is a source folder too, so that Eclipse will list it under the other source folders in the Project Explorer, even when another developer imports the project inside his IDE (i.e. without adding that folder as a source folder manually)?

This is the relevant part of my POM:

                    <directory>${basedir}/src/main/resources/release</directory>
