How gatling.conf get loaded when replacing it with an application.conf file

Gatling (Open-Source)
1

I am running gatling 1.5 in intelliJ 12.1.6
I replace gatling.conf with an application.conf file so that I could externalize some environment variable for my tests.
so I now have the following IDEPathHelper.scala:
import scala.tools.nsc.io.File
import scala.tools.nsc.io.Path.string2path

object IDEPathHelper {

val gatlingConfUrl = getClass.getClassLoader.getResource(“application.conf”).getPath
val projectRootDir = File(gatlingConfUrl).parents(2)

val mavenSourcesDirectory = projectRootDir / “src” / “test” / “scala”
val mavenResourcesDirectory = projectRootDir / “src” / “test” / “resources”
val mavenTargetDirectory = projectRootDir / “target”
val mavenBinariesDirectory = mavenTargetDirectory / “test-classes”

val dataDirectory = mavenResourcesDirectory / “data”
val requestBodiesDirectory = mavenResourcesDirectory / “request-bodies”

val recorderOutputDirectory = mavenSourcesDirectory
val resultsDirectory = mavenTargetDirectory / “results”
}

I want to change some gatling configuration value like using Apache instead of Netty and also change the number of retry value.
How do I get gatling.conf loaded? How are the default value run? Can I merge the 2 config file?

Note: I tried merging the 2 files but it didn’t work!!

Any help is much appreciated

I don't get you here. Could you explain, please?

You'll be on your own then, we've never tested Gatling with HttpComponent
3, and its support in async-http-client 2 is dropped.
HttpComponent 3 is old stuff anyway and can't compete with HttpComponent 4,
which is not supported at all.
