Hi,

 

I have the following Drools rule in Optaplanner:

 

rule "oneShiftPerDay"

    when

        $leftAssignment : ShiftAssignment($leftId : id, $employee : employee, $shiftDate : shiftDate, employee != null)

        $rightAssignment : ShiftAssignment(employee == $employee, shiftDate == $shiftDate, id > $leftId)

    then

        scoreHolder.addHardConstraintMatch(kcontext, -1);

end

 

But when I run the solver I get the following error:

 

09:02:46.128 [main] ERROR o.d.c.k.b.impl.AbstractKieModule - Unable to build KieBaseModel:defaultKieBase

Error importing : 'be.comp.permanenties.domain.solver.EmployeeAssignmentTotal'

How can I solve this error? Thanks.

 

Kind regards,
