Use swagger with Play 2.5

Open shayhz opened this issue 8 years ago • 8 comments

Hi,

I still don't understand if it's possible to add Swagger to play2.5. According to the instructions on the main page, I still get the exceptions described in previous issues. I know that there are a lot of discussions about it on the other issues, but I still don't understand the final answer - does it work or not.

Thanks,

Same problem here.

(the play version is 2.5.9, the swagger version is 1.5.3 and my project is with sub modules)

+1, it doesn't work for play 2.5 for us neither. Any help? Anyone managed to run this?

swagger-play 1.5.3 works fine with play 2.5.3

I'm seeing similar problems with swagger-play 1.5.3 and Play 2.5.14.
