Как создать модель, которая назначает работе время, сотрудника и оборудование? ⇐ JAVA

[Гость]

Context: This is my first time working with Timefold/Optaplanner, so I might have some incorrect understanding of everything.

I'm working on developing a Quarkus Timefold app using/modifying the food packaging example. The goal is to update the model to be able to assign a time, which would be based on the previous job, an employee with the required skill, and required equipment. My model currently has a Job and Line from the example, and I'm trying to add a new Employee class. However, I'm getting this error:

java.lang.IllegalArgumentException: The config (QueuedValuePlacerConfig(ValueSelectorConfig(jobs), ListChangeMoveSelectorConfig(ValueSelectorConfig(null), null))) has no entityClass configured and because there are multiple in the entityClassSet ([class org.acme.foodpackaging.domain.Line, class org.acme.foodpackaging.domain.Job]), it cannot be deduced automatically.

In the job class, I added

@PlanningVariable(valueRangeProviderRefs = "employees") private Employee employee; and in the PackagingSchedule class, I added

@ProblemFactCollectionProperty @ValueRangeProvider(id = "employees") private List employees; This is my employee class:

package org.acme.foodpackaging.domain; import java.time.LocalDateTime; import java.util.*; public class Employee { private Long id; private String name; private String operator; private LocalDateTime startDateTime; Set skills; // No-arg constructor required for OptaPlanner and Jackson public Employee() { } public Employee(Long id, String name, String operator, LocalDateTime startDateTime) { this.id = id; this.name = name; this.operator = operator; this.startDateTime = startDateTime; this.skills = null; } public Employee(Long id, String name, String operator, LocalDateTime startDateTime, Set skills) { this.id = id; this.name = name; this.operator = operator; this.startDateTime = startDateTime; this.skills = skills; } @Override public String toString() { return name; } // ************************************************************************ // Getters and setters // ************************************************************************ public Long getId() { return id; } public String getName() { return name; } public String getOperator() { return operator; } public LocalDateTime getStartDateTime() { return startDateTime; } public Set getSkills() { return skills; } } I believe this error is because the Job class, which was originally a PlanningEntity with no genuine planning variables, now contains a genuine planning variable. How do I correctly create this model?
