Latest version 3.0.27 of swagger-codegen-plugin generates 2 additional files which is breaking the build

Description

For swagger files (spec : 2.0) provided by one of our vendor Genesys, the build is failing with newer version of io.swagger.codegen.v3 : swagger-codegen-plugin : 3.0.27.

The reason for failure is that there are 2 additional files that are being generated, one being named "Schema.java". In this file there is import of io.swagger.v3.oas.annotations.media.Schema which comes from swagger-annotations library.

Sample maven project has been attached in the comments section. Just change swagger-codegen-maven-plugin version to 3.0.7 and notice that the project builds without any problems.

JDK: 1.8

For JDK 11, you need to add following dependency.

javax javaee-api 8.0 provided

Swagger-codegen version

3.0.27

Swagger declaration file content or url
