[JAVA] Codegen for multi server

Description

I want to generate a client for a yaml that handle different server urls depending on where I want to test. My client only gets the first url from the yaml. Is there a way to say what url is used for this client. Maybe to insert in the bash call?

Swagger-codegen version

swagger-codegen-cli-3.0.3-20181125.212437-36.jar

Swagger declaration file content or url

servers:
  - url: 'https://...'
    description: Staging system
  - url: 'https://...'
    description: Dev system

Command line used for generation

java -jar swagger-codegen-cli-3.jar generate -i api.yaml -l java -o api-client --group-id de.api --artifact-id api-client --git-repo-id api

Steps to reproduce

Add second server url and generate code

Start by reproducing the Java client generation command with the provided OpenAPI YAML containing staging and development servers, then trace where the generator handles the servers list. Determine how a generated client should select a server, including whether that choice can be passed through the command line. Done means the generated client supports the requested server selection instead of always using the first URL.
