Description

I used generatorName java with a simple Swagger 3.0 spec file.

I noticed that the withXml option of the Maven plugin is not used. After issuing mvn clean generate-sources the sources are not annotated with @Xml* annotations.

This can be verified with verbose maven pluging configuration option set to true where at the very end of execution I noticed:

"modelDocPath" : "docs/",
  "withXml" : false,
  "scmDeveloperConnection" : "scm:git:[email protected]:openapitools/openapi-generator.git",
  "feignVersion" : "9.x",
  "licenseUrl" : "http://unlicense.org",
  "jsr310" : "true",

To get generated model with @Xml* annotations, I used additionalProperties.

openapi-generator version

            <groupId>org.openapitools</groupId>
            <artifactId>openapi-generator-maven-plugin</artifactId>
            <version>4.1.1</version>

Seems to be working with

			<groupId>io.swagger.codegen.v3</groupId>
			<artifactId>swagger-codegen-maven-plugin</artifactId>
			<version>3.0.11</version>

OpenAPI declaration file content or url

Complete Maven example project: https://github.com/RockyMM/openapi-modelgen-test

Command line used for generation

mvn clean generate-sources

Suggest a fix

After 10 minute search (without cloning openapi-generator) I would start looking in AbstractJavaCodegen class, as the maven plugin class seems to be working correctly. But then again, I am really not not not familiar with the project.
