How to generate a client for XML?

[TPunkiee]

There is an existing service that produces XML responses and published its swagger definition. I wanted to generate a java client that can read those XML responses. The swagger-code-cli tool however produced me a JSON client using java -jar swagger-codegen-cli.jar generate -i theapi-l java --library jersey2.
How can generate an XML client?

Seems like some libraries are capable of handling XML but not all of them. Look for the libraries that use jackson for processing, like jersy1. The produced code is using JSON by default but you can adapt the code in the api service that calls the endpoint and remove the json reference and ask for xml instead.
Because jackson can handle XML and will determine how to parse the received reply based on the metadata it will load an xml parser. You might need to add the relevant dependencies though.
