programmatically setting baseUrl in java / retrofit2

Description

Using Java / retrofit2 client generation.

It generates ApiClient where baseUrl is locally set in createDefaultAdapter and passed to Retrofit.Builder.

I want to use this same generated code, but with different baseUrls programmatically.

That does not seem to be possible.

Swagger-codegen version

2.2.2-SNAPSHOT

Command line used for generation

java -jar ${swaggerCodegenJar} generate \
     -l java \
     --library retrofit2 \
     --group-id TO-BE-DELETED \
     --artifact-id java-retrofit2-client \
     --api-package api \
     --invoker-package invoker \
     --model-package model \
     -i DocService-folders-swagger.json \
     -o /tmp

Suggest a Fix

Rather than have a bunch of different constructors for ApiClient, use a "fluent/builder" style that includes baseUrl as one of its methods.
