swagger-codegen-maven-plugin with inflector language does not generate a controller

[Jeffrey Haynes]

I am trying to use the maven plugin to generate the controllers and the models for my swagger definition. The models generate just fine, but I can't get the controller to be generated.

If I use the swagger-codegen-cli, the controller is generated. Here is the command line that I am using:

$ swagger-codegen generate -l inflector --output generated --input-spec ./src/main/swagger/swagger.yaml

Any idea as to why the controller is not generated from maven? What am I missing?

Here is the maven plugin configuration:

It seems to be when I run the command:

$ swagger-codegen generate -l inflector --output generated --input-spec http://petstore.swagger.io/v2/swagger.json

Yes. swagger-codegen works when executed on the command line, but does not work with the swagger-codegen-maven-plugin. The maven plugin only generates the models. So, is there something that I'm missing in the plugin configuration? Or is the plugin broken?

Hi, the version you had for the codegen plugin seemed wrong--here's a complete pom that generates the controllers as you would expect:

Duh. Wow, that was a dumb error. I specified the swagger-inflector version as the version for the swager-codegen-maven-plugin... I need more coffee... :-)
