You’re using the lib from codecentric. It depends on scalikejdbc and this library is missing from your classpath.

Hello,
Thank you for your response but when i run ./gatling.sh -cp gatling-charts-highcharts-bundle-2.3.1/lib/gatling-jdbc_2.12-1.0.1.jar, I get Unknown argument as an error.
So i added in application.conf my # JDBC settings db.default.driver=“org.h2.Driver” … same errors too.

My question is if their is any another way to make it works .PS: even without codecentric, i just wanna use Gatling.
