Upgrade Gatling version

When you create your project with maven archetype, you might get the old version compared to the latest one. At the time I created, the archetype template had the version 3.2.x so I'm going to upgrade Gatling the latest version 3.5.1

Change Gatling version in pom.xml

Just change the gatling version in pom.xml file. Super easy!!

<!-- Change the version from 3.2.x to 3.5.1-->
<gatling.version>3.5.1</gatling.version>

Change gatling.conf

Refer the gatling.conf in this project.

Change files based on the latest version

You cannot use io.gatling.commons.util.PathHelper anymore so need to change it.

// Gatling v3.2.x

import io.gatling.commons.util.PathHelper._

object IDEPathHelper {

  val gatlingConfUrl: Path = getClass.getClassLoader.getResource("gatling.conf")
  val projectRootDir = gatlingConfUrl.ancestor(3)

...
}

Because of this change, you need to check Engine.scala and Recorder.scala as well.

Refer the files in this project.
