I updated my Play app with Scala 2.12 and Play 2.6.1, also I've changed Slick to v3.2 . Before (Scala 2.11.11 and Play 2.5.14) everything was working fine with Mysql driver version 5.1.23, which is the officially supported version, as said in this page: https://github.com/slick/slick . Now I get
java.lang.ClassNotFoundException: slick.driver.MySQLDriver
Also after several sbt clean. Is there any form of dependence between mysql driver and scala?
