FieldNameConstants FIELD_ not support

https://projectlombok.org/features/experimental/FieldNameConstants
Starting with lombok v1.18.6, lombok will silently skip generating anything that already exists. You can define the inner Fields enum/class yourself, in which case lombok will add all the enum constants / public static final fields you haven't written yourself.

From lombok v1.16.22 to lombok v1.18.2, this feature generated constants inside the type directly; the name of these fields would for example turn field exampleFieldName into public static final String FIELD_EXAMPLE_FIELD_NAME = "exampleFieldName";. The prefix and suffix (here, FIELD_, and the empty string) were configurable. Starting with lombok v1.18.4 this feature has been redesigned into generating an inner type as described above.
