Is anyone here successfully generating kotlin data classes from json schema in a pipeline? i.e. not using an android plugin

yes, we use internal (for now) gradle plugin for generating. based on https://github.com/OpenAPITools/openapi-generator

Thanks! How much work was it setting up the gradle plugin? Do you use the jar?

We do something similar

day or two... we have only one class with some custom logic of arguments mapping and have custom resources with our files templates

We use this plugin with a custom set of templates https://github.com/int128/gradle-swagger-generator-plugin

Thanks for the input!
