Hi,

I created Gatling script and everything working great while running Gatling.bat on local machine.  
When running same from Jenkins, throwing following error…!!  
Need help understanding what is missing.

GATLING\_HOME is set to “C:\Gatling\ABCD”  
JAVA = “java”  
ABCD is the only simulation, executing it.  
Select run description (optional)
