Gatling Gradle plugin not including transitive dependencies

Question

I am using the official Gatling Gradle plugin in my Scala project and I am seeing an issue where dependencies included like

dependencies {
    gatling "LibraryA"
}

are not including transitive dependencies. That is, I have a Gatling simulation class that extends a class from LibraryB which LibraryA depends on. However, when I try to run the simulation, I get an error like

Symbol 'type ClassFromTheTransitiveDependency' is missing from the classpath.

When I look at the Gradle dependencies, I see the LibraryB as a dependency of LibraryA. My IDE (IntelliJ) also recognizes it when clicking through the code.

I've tried searching through the single page of documentation for the plugin, but I don't see anything helpful there. Is this just not supported or am I missing something?

Thanks in advance, and please excuse my Gradle/build mediocrity if it's something simple!

Your post is very incomplete in the sense that there's no way to investigate and help you based on the information you've provided. Typically, you should provide a way to reproduce your issue, see http://sscce.org.

Here's what I did:

1. clone the official demo project
2. added a dependency to OkHttp (that depends transitively on okio and kotlin)
3. added code using OkHttp in the sample simulation
4. ran ./gradlew gatlingRun

dependencies {
    gatling 'com.squareup.okhttp3:okhttp:4.9.0'
}

  import okhttp3._
  val client = new OkHttpClient()
  val request = new Request.Builder().url("https://gatling.io").build
  println(client.newCall(request).execute().body.string())

Everything works just fine, so the issue is most likely on your side and not with gatling-gradle-plugin. I would recommend starting from the official sample and adding pieces one by one until you figure out which one breaks.
