With Swagger V3, the generators are no longer located in io.swagger.codegen.languages package in the swagger-codegen modules.

New location is in the swagger-codegen-generators repository and module.

Folder /swagger-codegen/modules/swagger-codegen/src/main/java/io/swagger/codegen/languages on the 3.0.0 branch is here to help with the migration. It contains dead code for the moment.

As announced in the v3.0.0-rc0 release notes, the initial focus is on the java and inflector generators. For the html generator, I have opened a pull request: swagger-api/swagger-codegen-generators#35

Once this pull request is solved, an initial version of the html generator will be present on the 3.0.0-SNAPSHOT version you are using.

[jmini]

My pull request was merged, please update to the latest swagger-codegen-cli.jar (or build it locally using the -U flag to be sure to get the latest version).

Please notice that this is an initial version (not only the generator is new with v3 but also the framework, the templating engine, the spec, the parser...), you might find some regressions that need to be adressed. Feedback is welcomed.

I think this issue can be closed.

@jmini I can confirm, all works now. Thank you

[jmini]
