Problem statement

the swagger CLI tool does not work correctly when the target repository is a Go 1.11 Module. The tool should not use GOPATH/src to resolve dependencies, and instead use the GOPATH/pkg/mod The possible failure cases I have discovered are as follows:

1. required dependency is not in GOPATH
   1. results in the CLI tool saying it cannot find dependency
2. dependency in GOPATH is not the same as declared in MODULE
   1. individual types/functions/packages fail, rather than the dependency as a whole
