Getting "Cannot resolve symbol core" while writing Gatling script - scala

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:
<?xml version="1.0" encoding="UTF-8"?>

What i want to achieve:
import io.gatling.core.scenario.Simulation
import io.gatling.core.Predef._
import io.gatling.http.Predef._

Answer 1

Or you should use only variables like ${"ANY_PACKAGE".version} or check the right version from the terminal.

Answer 2

Gatling creator here.
Really, as explained in my comment, your issue is most likely that you have a corrupted gatling-core-3.5.1.jar in your local maven cache. Just remove it from there and re-trigger the maven download and it will be fine.
Hope it helps anyone stumbling on this thread.

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