UnexpectedException: Unexpected exception[ExceptionInInitializerError: null]

[odwrotnie]

I get play.api.UnexpectedException: Unexpected exception[ExceptionInInitializerError: null] after play new, adding slick.default="models.*" to application.conf and creating the model:

package models

import play.api.db.slick.Config.driver._

case class Cat(name: String, color: String)

object Cats extends Table[Cat]("CAT") {

  def name = column[String]("name", O.PrimaryKey)
  def color = column[String]("color", O.NotNull)

  def * = name ~ color <> (Cat.apply _, Cat.unapply _)
}

You have to add:

db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:mem:play"
db.default.user=sa
db.default.password=""

to application.conf.
