Gatling 3.0.3 neither it's showing my simulation nor it's throwing any error

I created a couple of simulations and they are not showing up when I am trying to execute via command line. I do have a couple which i recorded and they are showing up. I just edited a couple them and created a copy of them and they are not showing up. Below is the scala script in that simulation.

`
package test1

import scala.concurrent.duration._

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import io.gatling.jdbc.Predef._

class RecordedSimulation123 extends Simulation {

val httpProtocol = http
.baseUrl(“https://abc.com”) // Here is the root for all relative URLs

val header = Map(
“Content-Type” → “application/soap+xml;charset=UTF-8”,
“Connection” → “alive”,
“User-agent” → “Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0”)

val scn = scenario(“RecordedSimulation”)
.exec(http(“request_0”)
.get("")
.headers(header))

setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)
}
`

Now all of a sudden, after I moved the newly created scripts to the folders under user simulations, I am getting the following error:

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

All my scripts are as it as and they are extending Simulation.

Thanks,
Vikram
