Publish for Play 2.7 + slick 3.2?

[ashleymercer]

Would it be easy / possible to publish a version that is compatible with Play 2.7, but slick 3.2?

It looks like there are some moderately serious issues with the new java.time support in slick 3.3 (see here, and here, and here, ...) and so not being able to upgrade slick for the time becomes a blocker for upgrading to Play 2.7.

@ashleymercer, that won't be possible because Play 2.7.x uses a version of Hikari that is incompatible with Slick 3.2.

Basically, Slick 3.2 was using an old version of Hikari and was calling a deprecated method that was then removed. See slick/slick#1821

Play 2.7.x uses a recent version of Hikari and when mixed with Slick 3.2, that removed method is not found and blows up at runtime.

Ahh thanks for the explanation - suspected / feared there would be something like this! Fortunately it looks like the slick people are working on making the support for java.time optional (or allowing overrides with local implicits) so I'll wait for that work to be finished.
