Scala equivalent of Java's Class[] is Array[Class[_]]

Try:

override def preRootContextClassConfiguration() = Array(
  classOf[DatabaseSourceConfig],
  classOf[DatabaseJpaConfig],
  ...
)

The below code should replace your java function. A very nice feature of Scala is that you rarely have to declare your type in advance, the compiler will do the checking for you...

override def protected preRootContextClassConfiguration() = {
  Array(DatabaseSourceConfig.class, DatabaseJpaConfig.class, ...)
}
