How to run a single simulation via maven in gatling 3.0.0

[ankit jasuja]

Hi All,

I am migrating from gatling 2.*.* to 3.0.0. I am using maven to build and run the simulations.

In gatling 2.*.*, I used to specify mvn gatling:execute -Dgatling.simulation=[fullyQualifiedSimulationClassName]

In gatling 3.0.0, I am aware of that we have to use mvn gatling:test as the goal. The stuff that I couldn't find is how to run a single simulation class via maven.

Is anyone aware of the above?

Thanks,

Ankit

Not sure, but you might be looking for:

   -Dgatling.simulationClass=[fullyQualifiedSimulationClassName]    rather than  -Dgatling.simulation=  as you stated above.

If thats not the solution, I see an article here that looks like it might work for you:

Thanks Jon for replying.

In both the cases, I am getting this exception.

that sounds to me like you need to fix an import at the top of your simulation script.  OR the error looks like a method your using has changed.   just guessing...
