Way too old set up, in particular the gatling (latest 3.10.3) and gatling-maven-plugin version (latest 4.8.0).
We can only help if you upgrade to latest versions.
Please check the demo project for maven+scala: GitHub - gatling/gatling-maven-plugin-demo-scala: Showcase of the Gatling Plugin for Maven + Scala

:man_facepalming: That’s a recent regression. I’ve just fixed it, please upgrade to gatling-maven-plugin 4.8.1 (the demo project has been updated as well).
