My Repository interface is like this:

public interface DefinitionProcessRepository extends DefinitionProcessRepositoryBase, JpaRepository {

@Query( "select new Map( " + " dp.id as id, " + " avg(cast(date_diff(d, it.dateCreation, it.closingDate) as double)) as MediumInstanceTask," +
" avg(cast(date_diff(d, it.maturityDate, it.closingDate) as double)) as anotherMediumInstanceTask " + ") from DefinitionProcess dp " + "inner join dp.instanceProcess ip " + "inner join ip.instanceTasks it " + "where dp.id in (:id) and it.closingDate is not null " + "group by dp.id")
List> mediumTempInstanceTask(@Param("id") List id);

}

I don't know how to resolve this error.
Any help will be appreciated
