Hi, I updated the Gatling version to 3.4.0 and sbt plugin to 3.2.0 an I have a problem loading the environment configuration file. I use “com.typesafe” % “config” % "1.4.0 to pass param.

Part of the code to get conf\_file.

For “gatling-sbt 3.2.0”:  
When I run test like sbt -Dconfig=prod\_application.con “gatling:testOnly simulations.test”  
and print line from the code “CONFIG\_FILE\_PRINT”. I get “CONFIG\_FILE\_NAME: None” in terminal.  
Moreover, when I run test with property noReports: sbt -Dgatling.charting.noReports=true “gatling:testOnly simulations.test”. report was generated. I expected only simulation.log and instead I have index.html. It looks like, with the new plugin, set properties don’t work.

When I set again to “gatling-sbt” to 3.1.0 in plugin.sbt file and I have Gatling in 3.4.0 version everything works fine and I get message CONFIG\_FILE\_NAME: Some(prod\_application.con) in the terminal. And I can pass param to the test.

Please help me out because I don’t know if it’s bug or maybe I am doing something wrong. In older version of gatling and sbt-plugin everything worked fine and I have never got a problem to pass param.

Regards,  
Daniel

Indeed, it looks like a regression. Thanks for reporting.  
I guess the culprit is [https://github.com/gatling/gatling-sbt-plugin/commit/0afb0a35c983b3ca29e0fa663309195f78716f93](https://github.com/gatling/gatling-sbt-plugin/commit/0afb0a35c983b3ca29e0fa663309195f78716f93)

Thanks for quick answer Stephane. Can I use gatling 3.4.0 with gatling-sbt 3.1.0 or better to get back to previous version of gatling?

You can use Gatling 3.4.0 with gatling-sbt 3.1.0, no need to rollback Gatling.

Could you please give gatling-sbt 3.2.1 a try?

Your pom is correct.

What most likely happens here is that maven corrupted the “gatling-charts-highcharts” library while downloading it so you end up with a corrupted jar in your local maven cache. Sadly, maven doesn’t verify artifacts checksums as part of its download process (I think gradle does).  
You can verify this by trying to unzip the jar stored in your local maven cache. It’s located by default in ~/.m2/repository/io/gatling/gatling-charts-highcharts/[3.3.1.](http://3.3.1.)  
If so, remove the whole directory and try again so you trigger download again.

If it still doesn’t work, it might mean you’re using an Enterprise maven proxy (such as Nexus or Artifactory) and that the corrupted copy is stored upstream there. If so, you have to contact the administrators so they remove the corrupted file.
