Please note that the name of the class over time has been changed, in that one 'D' has changed from its uppercase to a lowercase 'd', ie: QueryDslPredicateExecutor is now QuerydslPredicateExecutor. Probably this caused some headache for you as it did for me too.

Refer to the class in your source code as QuerydslPredicateExecutor and your source code will build again.
