swagger unable to generate client for specification

[infominer75]

Swagger is unable to generate Http client for a swagger 3.0 specification.

I have downloaded the swagger pre-compiled binary. I am trying to generate the API client using the instructions present here:
https://goswagger.io/generate/client.html

The link for requirements details certain dependencies that must be got using go get. However, it is not clear if these are required during the generation process itself.

Requirements link : https://goswagger.io/generate/requirements.html

Swagger specification

Swagger specification can be found here:

https://raw.githubusercontent.com/goharbor/pluggable-scanner-spec/master/api/spec/scanner-adapter-openapi-v1.0.yaml

Steps to reproduce

The below code snippet provides the command executed and the corresponding output

swagger generate client -f https://raw.githubusercontent.com/goharbor/pluggable-scanner-spec/master/api/spec/scanner-adapter-openapi-v1.0.yaml

go-swagger currently only supports Openapi v2.0

@fredbi love this tool - best of both worlds (api-first, live docs)

This is worth sharing

https://dev.to/derberg/convert-swagger-2-0-to-openapi-3-0-3joj

shows how to convert to OAS 3.0 using another tool. That worked like a charm for my project. ;-)

I have a similar issue with OpenAPI 3.0.1. Does go-swagger still support only OpenAPI 2.0?

[casualjim]

yes. we have no plans to support openapi 3.0
