Why can't I renew the playFrameworks NingWSComponents? (game 2.6.0)

From what I understand to use instance WSClient

you need to mix NingWSComponents

like this guy, answer here how to install dependencies for a service using MacWire (play framework) .

But this dosent work ... intellij doesn't recognize NingWSComponents

and this guy is using it here http://loicdescotte.github.io/posts/play24-compile-time-di/

its really weird ...

thankks
