Getting "Cannot resolve symbol core" while writing Gatling script

Question

I am trying create a Gatling load test script on Intellij Idea and I'm at the very beginning steps. I created a Gatling project with Maven but i cannot import io.gatling.core package.

Could you please help me to resolve my issue? Thanks in advance.

My pom.xml file:

import io.gatling.core.scenario.Simulation
import io.gatling.core.Predef._
import io.gatling.http.Predef._

I changed my pom.xml to below with Gatling 3.5.1 and it works now:
