Two things.

First, you are probably getting the error when choosing swagger from the generate client menu. That option is really intended for converting swagger specifications from 1.x to 2.0 and downloading the JSON representation. For the editor's sake, it's really not even needed. We'll hide it.

Second, there was one defect when generating java clients from your spec. That's been fixed.

If you see issues in the code generation, please open them here:
