[BUG] [SPRING] Tags are not affecting generated code

[oburgosm]

Description

I'm using openapi-generator-maven-plugin to generate spring rest service. According to documentation, tags must affect generated code, but this is not happening

openapi-generator version

v4.0.2

OpenAPI declaration file content or url

...
paths:
  /product:
    get:
      tags:
        - other
...

Command line used for generation

I found that exists parameter useTags, with false as default value. If I set it to true, Generated classes are grouping by tags.

In my previous code:

<plugin>
  <groupId>org.openapitools</groupId>
  <artifactId>openapi-generator-maven-plugin</artifactId>
  <executions>
    <execution>
      <id>generate-rest-api</id>
      <goals>
        <goal>generate</goal>
      </goals>
      <phase>generate-sources</phase>
      <configuration>
        <inputSpec>/exampleinput</inputSpec>
        <generatorName>spring</generatorName>
        <configOptions>
          <dateLibrary>java8</dateLibrary>
          <java8>true</java8>
          <interfaceOnly>true</interfaceOnly>
          <reactive>false</reactive>
          <apiPackage>my.apipackage</apiPackage>
          <modelPackage>my.modelpackage</modelPackage>
          <sourceFolder>src/gen/java/main</sourceFolder>
          <serializableModel>true</serializableModel>
          <useTags>true</useTags>
        </configOptions>
      </configuration>
    </execution>
  </executions>
</plugin>

found out it is actually issue on other side - openapi generator.
