NoClassDefFoundError with 3.0.1

[klclee]

Hi there I am runing Play 2.6.5 and play-slick 3.0.1. When I run my inetgration tests I am getting the following exception. (Reverting back to 3.0.0 stops it)

A needed class was not found. This could be due to an error in your runpath. Missing class: slick/lifted/MappedProjection$

And line 63 that is referencing in the exception is:

 def * = (id,email,inviteToken,userId, createdAt) <> (PendingInvite.tupled, PendingInvite.unapply _)

Still present in play-slick 3.0.2 and play 2.6.6.

You probably have a something that's using Slick 3.2.0, but play-slick is using 3.2.1. Unfortunately a binary incompatible change was introduced in 3.2.1 by removing the MappedProjection object: https://github.com/slick/slick/commit/ddb75a0f96fdde48bbb6885c4636bae204515a69#diff-46e14ef7bc9ed87b5f6fec2283b9f97bL388

Gross, that should've forced a 4.0.
