Hi all. i am trying to generate kotlin from a Yaml file (with swagger codegen). And i have a lot of dependency problem, does anyone has already try it ?

If you aren't already, I'd suggest using this generator. https://openapi-generator.tech If you're using the above linked generator, then I have some experience with it, so may be able to help.

thanks i will check with this library

This plugin is also interesting: https://github.com/int128/gradle-swagger-generator-plugin I do not really like automatic code generation tools, but this is easy to use.

The int128 one hasn't been updated in 5 months, and just refernces the openapi-generator. I'd suggest just using the openapi-generator directly. I've found it very easy to use, and actively maintained.

data point. I have most recently tried and used this gradle plugin: id 'org.hidetake.swagger.generator' version '2.16.0' Took a few tries at others to find the one with the versions of codegen that worked for me. its not anything fancier then a plugin for swagger-codegen, but does work and supports ALL the parameters (ya the ones you cant find in the docs) for codgen. Recently used it to codegen a java and kotlin set of client API's for a public swagger API. Easily accepted some template mods and confiigs to 'tune' the kotlin codegen, particulary the class names if the spec doesnt use operation id.

This looks like it wraps/leverages the generator I linked above for code generation. And then provides some additional options for using other generators to produce other items. Note that OpenAPI generator is now on 4+, and this is using 3. One thing I like about the OpenAPI fork of swagger gen is it doesn't require different versions of the generator to target v2 and v3 of the Specification.

That part was annoying (getting the right version) -- was difficult even figuring out there were versions, where they were and what they did.
