How to run Gatling maven project as a Jar on EC2 machine

Hello everyone,
I’ve a gatling-maven project which works fine locally. I am able to run the gatling simulation class as a jar file in my local machine using maven assembly plugin. But I would like to run my gatling project jar file on an EC2 instance. I copied my jar file on to my EC2 machine and used the command that I use in my local machine. But I’m getting some error

17:36:08.511 [] INFO akka.event.slf4j.Slf4jLogger - Slf4jLogger started

The requested class ‘SmokeTest’ can not be found in the classpath or does not extends Simulation.

There is no simulation script. Please check that your scripts are in user-files/simulations

anyone have any idea about this issue? Please help
