Hi,

I’ve this error :

Error: Unknown option --ro  
Error: Unknown argument ‘true’

when :  
mvn gatling:execute -Dgatling.reportsOnly=true  
with last 2.0.0-snapshot

I don’t know if it’s normal, if I use correctly maven gatling plugin ?

Regards,

reportsOnly argument is not a boolean, it’s the name of the result folder that contains the log files you want to generate the reports for.  
Are you sure you’re not confusing for noReports? reportsOnly is not exactly the thing I’d run from maven…

Yes reportsOnly, I’ve a strange issue with a simulation which appears sometimes, and I wanted to try regenerate report.  
[https://github.com/excilys/gatling/wiki/Maven-plugin](https://github.com/excilys/gatling/wiki/Maven-plugin) suggests a boolean value…

Error: Unknown option --ro  
Error: Unknown argument ‘validatorsimulation-20140606145038’
