Getting "There is no simulation script."

I downloaded the gatling 2.3.0 zip and extracted it on my local machine (OSX). I’m running ./bin/gatling.sh and I’m getting this error message: “There is no simulation script. Please check that your scripts are in user-files/simulations”. My GATLING_HOME is set to the gatling directory.

switching from java 9 to java 8 fixed it.
