I am running Gatling from IntelliJ.  
My Simulation classes are located in src/test/scala along with Engine and Recorder classes.  
This setup works fine with gatling version 1.3.4 that I used before.  
However I tried upgrading to 1.4.6 and when I run the Engine class, I am getting an illegal argument exception and the message saying: _Did you forget to migrate your scenarios_  
Here is my pom.xml:

The message: “did you forget to migrate?” is a serious hint: [https://github.com/excilys/gatling/wiki/Migrating#wiki-1.4.0](https://github.com/excilys/gatling/wiki/Migrating#wiki-1.4.0)
