The migration guide for Gatling 2.1.1 states:

`

### Compiler runs standalone

Gatling itself doesn’t compile the Simulations anymore and expects that the simulations are already compiled. This means that gatling.sh/gatling.bat and the Maven plugin runs the compiler prior to running Gatling. Consequently, a few options in gatling.conf have been removed:

- `gatling.core.disableCompiler`
- `gatling.core.zinc.jvmArgs`

`

Going into my IDEAPathHeper it looks like this:

`

```auto
import scala.tools.nsc.io.File
import scala.tools.nsc.io.Path.string2path

object IDEPathHelper {

 val gatlingConfUrl = getClass.getClassLoader.getResource("gatling.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"

 val recorderConfigFile = (mavenResourcesDirectory / "recorder.conf").toFile
}

```

`

It shows red on the .tools and File in the text above and complains when trying to Rebuild solution in IntelliJ.

What should I do to get rid of these warnings?

Remove .toFile, it’ll work.
