Lack of configuration option in ‘Swagger Gradle Plugin’, which allows to specify discriminator and discriminator mapping

[ideas-into-software]

Currently, to the best of my knowledge, there is no configuration option in ‘Swagger Gradle Plugin’ (https://github.com/swagger-api/swagger-core/blob/master/modules/swagger-gradle-plugin/README.md), which allows to specify discriminator and discriminator mapping – required in models with class inheritance. E.g. in models based on the ‘GeoJSON’ standard (https://geojson.org/), Swagger does not have sufficient information on how to map Geometry sub-types such as Point, LineString, Polygon, etc.

I do realize Swagger Annotations can be used in such cases to add discriminator and discriminator-mapping, but our model code is generated off EMF Ecore, therefore we cannot include any custom annotations as these would get overwritten on each build; see eclipse-emf/org.eclipse.emf#27 for more details.
