Maven gatling issue

I am trying to configure profile for dev and prod in pom.xml

so that I can use respective data directory to read execution parameter but it is still reading default dir only.

Dev\run_param
no_users,ramp_time
1,10

Prod\run_param
no_users,ramp_time
100,10

Also I want to feed this value in setUp(scn.users($NO_USER).protocolConfig(httpConf)) any idea on it.
