Incompatible Jackson version: 2.7.1

[luos]

Hi!

I am trying to use this lib to generate but I get this exception, I use play 2.5.

My definition file is one of the example plus produces : application\json line added because without that it did not even work at all by saying that The server doesn't support any of the requested mime types.

Any idea what should I do to make this work? Tried including the same jackson versions as in this repo but the error is the same.

Thanks,
@luos

@luos Thanks for the bug report! Currently, the plugin is only tested with play 2.4
I'm pretty sure play 2.5 uses different versions of it's dependencies, including Jackson.

Could you please try the plugin with play 2.4 ?

Hi if it helps... I changed to 2.4 and it works!
