Maven RPM plugin: Different content for CentOS 6.5 and 5.6

I have been using rpm-maven-plugin to generate RPMs to install on CentOS 6.5. Now I need to extend it to package an RPM with binaries compiled on CentOS 5.6. My development machine is OSX and I would like to be able to test RPM generation for CentOS 6.5 and 5.6 on it. Which means that I should be able to pass the target OS as a command line parameter. Any ideas on how to do this?

I looked through the plugin's documentation and it seems like I need to use filter, but nowhere I can find how to determine the value for that classifier for CentOS 5.6 and 6.5.

Thanks!

I ended up creating two separate maven-rpm-plugin executions: one - for CentOS 6.5 and one - for CentOS 5.6. I also disabled automatic uploading of RPMs to Maven repo during release process because the two RPMs had the same name. I disabled uploading by adding -Dmaven.deploy.skip=true to maven-release-plugin section.

Here is a relevant excerpt from my pom.xml (can be executed with mvn package):
