Hi,  
Earlier I was using ABCD in my pom.xml file.  
I ran “mvn test” in the command line and everything worked fine.

Now, I want to specify class in command line rather than in pom.  
I gave the command as,  
mvn test -Ds=“ABCD”  
but this doesn’t work.  
It says, More than 1 simulation to run, need to specify one

What is the correct format to mention the class?

Note - My class is directly available in src/test/scala without any other package declaration.

Use the full property name. The “s” alias wasn’t working because it’s a reserved maven alias for the settings.xml file location.

See [https://github.com/excilys/gatling/issues/1037](https://github.com/excilys/gatling/issues/1037)

Depending on the version you use, the full property name is either “gatling.simulation” or “gatling.simulationClass”.

Cheers,

Stéphane
