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'

Rule Compilation error : [Rule name='oneShiftPerDay']

be/comp/permanenties/solver/Rule_oneShiftPerDay544009415.java (2:978) : Only a

How can I solve this error? Thanks.
Kind regards,
Nick

I'm unable to figure it out. At the top of the drl file I have:
package be.comp.permanenties.solver; //permanentiesScoreRules.drl
dialect "java"
import org.optaplanner.core.api.score.buildin.hardsoft.HardSoftScoreHolder;
import be.comp.permanenties.domain.DayOfWeek;
import be.comp.permanenties.domain.Employee;
import be.comp.permanenties.domain.ShiftAssignment;
import be.comp.permanenties.domain.Roster;
import be.comp.permanenties.domain.RosterInfo;
import be.comp.permanenties.domain.Shift;
import be.comp.permanenties.domain.ShiftDate;
import be.comp.permanenties.domain.ShiftType;
import be.comp.permanenties.domain.ShiftTypeSkillRequirement;
import be.comp.permanenties.domain.Skill;
import be.comp.permanenties.domain.request.DayOffRequest;
import be.comp.permanenties.domain.request.DayOnRequest;
import be.comp.permanenties.domain.request.ShiftOffRequest;
import be.comp.permanenties.domain.request.ShiftOnRequest;
import be.comp.permanenties.domain.solver.EmployeeAssignmentTotal;
import be.comp.permanenties.domain.solver.EmployeeWorkSequence;
The EmployeeAssignmentTotal sits in the right package and the top of the
file is:
package be.comp.permanenties.solver;
import java.io.Serializable;
import org.apache.commons.lang.builder.CompareToBuilder;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import be.comp.permanenties.domain.Employee;
public class EmployeeAssignmentTotal implements
Comparable<EmployeeAssignmentTotal>, Serializable {
For now the project is just a copy of the nurse rostering problem with some
omissions of things I don't think I will need. I am now trying to get
something fairly simple up and running. The program will replace a manual
employee planning tool in Excel. But the planning tool they use now doesn't
look at holidays or days off. The aim of the program is to do everything
automatically and integrate it with the hour registration program. But as
you can see I am only beginning. Deadline is the end of this year.
Kind regards,
Nick

The EmployeeAssignmentTotal sits in the right package and the top of the
file is:
package be.comp.permanenties.solver;
Shouldn't that be instead:
package be.comp.permanenties.domain.solver;
because of (1)?

It was indeed a wrongly named import. Thanks for the help.
Kind regards,
Nick
