withXml true is not generating the java classes with xmlelement annotations

[selva-krishnan]

Description

The codegen plugin withXml true is not generating the java classes with @xmlelement. It works with swagger-codegen plugin though.

openapi-generator version

5.0.1

OpenAPI declaration file content or url

You can test it with sample Pet store swagger from - https://editor.swagger.io/

Command line used for generation

mvn clean compile

Steps to reproduce

Download the sample YAML from the PetStore example and generate the classes using generatorName - java and withXml - true. The classes are missing the xmlelement annotation. But when the same config is used with swagger-codegen-maven plugin version 3.0.25, It generated the classes and adds xmlelement annotation to the fields.

I can see those annotations in the model files, e.g. https://github.com/OpenAPITools/openapi-generator/blob/master/samples/client/petstore/java/resttemplate-withXml/src/main/java/org/openapitools/client/model/Pet.java
