Problem statement

swagger generate server -A go-planting -f swagger.yml fails on Transformed Spec. After a preliminary review of the spec, it is not seen why the resulting go code has cycles in them.

Swagger specification

2.0

Steps to reproduce

First some background. I am porting an old clojure application over to golang. I took the swagger.json from that service and then did the following to transform it to an OpenAPI v2.0 specification. the swagger.json was tranformed to YAML using
the following online tool. Further processing was required because the swagger.io tool produced an OpenAPI v3.0 spec. To convert the OpenAPI v3.0 spec to a OpenAPI v2.0 (swagger) spec, an account was created at APIMATIC and the spec was "transformed" using the Transform API button.

After the OpenAPI v2.0 (swagger) spec was generated and validated. The following command was run:

swagger generate server -A go-planting -f swagger.yml

Subsequently, the following commands were run to build the server:

go mod tidy && \
   cd cmd/go-planting-server && \
   go build

This resulted in a build error. Somehow the spec or swagger generates go code with cycles in them. The errors are as follows:
