I just updated to 2.1.2, and when I tried to run my standard startup script, I got a bunch of errors about unknown options and arguments. It would appear that the long forms were removed. Was that a conscious decision? Was there any particular reason for it?
Hi John,
Found the cause : since 2.1.2, the compiler does some argument parsing to support options the -s option, but does not support all of Gatling options, which leads to those warnings.
They are however, completely harmless, and should be therefore hidden.
Will fix that 
Cheers,
Pierre
FYI seems like short args fail as well
/usr/share/gatling-2.1.2/bin/gatling.sh -s BasicSimulation
GATLING_HOME is set to /usr/share/gatling-2.1.2
Warning: Unknown option -s
Warning: Unknown argument ‘BasicSimulation’
The requested class(‘BasicSimulation’) can not be found in the classpath or does not extends Simulation.
Choose a simulation number:
[0] computerdatabase.BasicSimulation
Hi,
The first two warnings are caused by the issue that I explained before, which will be fixed in 2.1.3.
When using the -s option, you must pass the fully qualified class name, e.g. computerdatabase.BasicSimulation.
This explains why this doesn’t work in this your case.
Cheers,
Pierre
Hi Pierre,
When I run 2.1.2 on AWS-Ubuntu, I get a lot of error messages and it causes Fabric to halt processing. If I ssh into the single host then the process keeps going in-spite of errors.
I need to run some tests next week. In the meantime, can you tell me where can I download 2.0.3 bundle
Here is the error output

Nevermind. I found the issue. My tar command corrupted gatling lib files. I am downloading gatling directly on the boxes
Thanks for explaining Pierre…
