[JAVA] Generate code without library/dependencies

Description

I am coming from JAXWS background where I can point xjc (or related maven plugins) at wsdl file and generate the necessary interfaces without dependency on a particular client and deserializers. How can I achieve the same thing with swagger codegen tool?

In addition, when generating code with maven plugin, the tool writes additional src/main/java directories under target/generated-sources/swagger/ even with support files disabled. How do I prevent that?

Swagger-codegen version

3.0.27 maven-plugin

Swagger declaration file content or url

No.

Command line used for generation

              <configuration>
                <inputSpec>${project.basedir}/src/main/resources/document-service.json</inputSpec>
                <language>java</language>
                <generateSupportingFiles>false</generateSupportingFiles>
                <generateApis>false</generateApis>
                <generateModels>true</generateModels>
                <generateApiDocumentation>false</generateApiDocumentation>
                <generateModelDocumentation>false</generateModelDocumentation>
                <verbose>true</verbose>
                <modelPackage>se..document.model</modelPackage>
              </configuration>

Steps to reproduce

Take any openapi spec and generate it with java language

Suggest a fix/enhancement

It would be better if I could generate just the interface for functions provided by endpoints and implement it myself using my own client and models without using some sort of deserializer.

Start by examining the Java generator and Maven plugin handling for generateSupportingFiles, generateApis, and generateModels. Determine whether the requested interface-only generation and avoidance of extra src/main/java directories can be specified independently, then verify the behavior with an OpenAPI spec and the provided Maven configuration.
