In gatling, I got an error with "Exception in thread "main" java.lang.ExceptionInInitializerError" - gatling

Question

When I run Engine.scala under the scala directory，it gives an error:
Exception in thread "main" java.lang.ExceptionInInitializerError

And BaiduHomePageSimulation.scala is:
package test.scala
import io.gatling.core.Predef._
import io.gatling.http.Predef._
class BaiduSimulation extends Simulation {
// Set the root path of the request
val httpConf = http.baseUrl("https://www.baidu.com")
/*
run 10 seconds, during：the default unit is seconds, if you want to use microseconds eg. during(100 millisecond)
*/
val scn = scenario("BaiduSimulation").during(10){
exec(http("baidu_home").get("/"))
}
// set the thread count
setUp(scn.inject(atOnceUsers(10)).protocols(httpConf))
}
I don't konw how to fix it? Has anyone encountered a similar issue?

I was getting this error and was able to resolve it by marking the scala directory as Test Sources Root
Right click scala folder > Mark directory as > Test Sources Root
