Need help regarding engine.scala

While running my simulation via engine.scala , its not going forward its just stick upto below mention execution-

22:00:07,002 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy]

computerdatabase.BasicSimulation is the only simulation, executing it.
Select simulation id (default is ‘basicsimulation’). Accepted characters are a-z, A-Z, 0-9, - and _

BUT while running from maven install its excuting fine.Can you tell me what i am doing wrong?

One guess - the system properties being used from Maven & Engine.scale are different

mvn -Dgatling.simulationClass=computerdatabase.BasicSimulation

versus

-Dgatling.core.simulationClass=computerdatabase.BasicSimulation

Thanks in advance,
