I am using some code generated by GTPChat.

One of the files generated is called EnergyScheduleSolution.java and it has two associated imports:
import ai.timefold.solver.core.api.domain.variable.PlanningEntityProperty;
import ai.timefold.solver.core.api.domain.variable.PlanningScore;
And associated annotations:
@PlanningScore and @PlanningEntityProperty

I get the following errors in my eclipse ide:
The import ai.timefold.solver.core.api.domain.variable.PlanningEntityProperty cannot be resolved
The import ai.timefold.solver.core.api.domain.variable.PlanningScore cannot be resolved
PlanningEntityProperty cannot be resolved to a type
PlanningScore cannot be resolved to a type

What am I missing?

Thanks for any steers on this.

I have googled around for the imports to no avail. I think the two pairs of errors are related. But I cannot find anything that matches the problem.
