Passing maven variables

[DavidWilliams]

We are currently passing the -Dserver= <variable> on the mvn command line. 
 This variable is referenced in the pom in the following manor.
                <resource>
 <directory>src/main/${server}/resources</directory>
                                <filtering>true</filtering>
                </resource>
Is it possible to set this variable in the settings.xml file and pass it 
to the pom?

Thanks,
