How to set lombok.equalsAndHashCode.callSuper = call in spring application.properties?

Question

I use Lombok on Hibernate entities, and have inheritance:

@MappedSuperclass
@Data
public class BaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private Boolean enabled;
    public BaseEntity() {
        enabled = true; 
    }
}

@Entity
@Data
public class Event extends BaseEntity {
    private String name;
    private LocalDateTime start;
    private LocalDateTime end;
    private Boolean isTaxable;
}

Eclipse warns on child @Data:

Generating equals/hashCode implementation but without a call to superclass, even though this class does not extend java.lang.Object. If this is intentional, add '@EqualsAndHashCode(callSuper=false)' to your type.

as mentioned here Warning equals/hashCode on @Data annotation lombok with inheritance

I can use

lombok.equalsAndHashCode.callSuper = call

how can I use this property in spring application.properties file? Should I create lombok.config file near the application.properties and put it there instead?

I tried to add it to application.properties

lombok.equalsAndHashCode.callSuper = call

but Eclipse says this property unknown and Warning on child class @Data annotation still present.

As lombok is an annotation processor, it does its work during compilation. Thus, everything you want to configure in lombok has to be present when building your project.

You have to put all lombok configuration options into a file named lombok.config. This file is typically placed in your project root folder. For details, see the lombok documentation. (Note that this file will not be contained in the built artifact, e.g. the JAR file.)

You cannot configure lombok at runtime (e.g., using an application.properties).
