@FieldNameConstants. If you'd like to use @FieldNameConstants to for example fill in the of and/or exclude parameters of @ToString and similar lombok annotations, use the @ToString.Include / @ToString.Exclude etc system instead; these are described at the feature pages for those features.
Like other lombok handlers that touch fields, any field whose name starts with a dollar ($) symbol is skipped entirely. Such a field will not be modified at all. Static fields are also skipped.

+ MapStruct interop: When making references to field name constants inside MapStruct's @Mapping, and you use that annotation more than once on a node, you must manually wrap these in the @Mappings 'container annotation'. Like so: @Mappings({@Mapping(target = Entity.Fields.entityProperty, source = "dtoProperty")}).
