Gatling and Scala generation

Swagger-codegen

I want to use the generated scala classes in a Gatling test scenario. But no gatling report is generated because no execution chain is invoked in the generated InvokeApi. I am using eclipse.

Caused by: java.lang.UnsupportedOperationException: There were no requests sent during the simulation, reports won't be generated

Swagger declaration file content or url

Command line used for generation

Scala
Scala-editor - manually convert the swagger.json
Java 8
STS
Maven

Steps to reproduce

1. Get a REST server swagger json
2. Use it to generate scala client code.
3. Try to create a Gatling scenario with the generated scala classes.
4. Start the gatling test.

Introduce a Gatling scala code generation option and add it in Swagger-editor

Start by reproducing the reported failure with Swagger-codegen 2.2.1, a generated Scala client, and the Gatling scenario described in the issue. Then investigate the Scala generation flow and the Swagger-editor option requested. Done means generated Scala code can invoke the execution chain and a Gatling report is produced.
