requested class can not be found in the classpath

Hi All … I simply extracted a HAR file with the recorder and trying to executed with gatling.sh . I am just trying to

Execute the script , but it complains about the missing classes . I checked the target/test-classes folder and there

are no related class files created . I assume gatling does the compilation automatically . I am in version 2.1.6.

Any help pls…

The requested class(‘XXXXXXXX’) can not be found in the classpath or does not extends Simulation

Thanks
