✅ Why we didn't get errors when using @SuperBuilder

When we had:

@SuperBuilder
public class Organization extends BaseEntity { ... }

MapStruct generated the Organization like this internally:

Organization.builder()
    .createdAt(...)     // works even if there's no public setter!
    .name(...)
    .build();

✅ This works because @SuperBuilder gives MapStruct full control to set values via builder methods, including private fields like createdAt that don’t have public setters.

Even if createdAt had:

@Setter(AccessLevel.PRIVATE)

it doesn't matter — the builder has access.

❌ Why it breaks without @SuperBuilder

When you remove @SuperBuilder, MapStruct falls back to the default no-args constructor and JavaBeans-style property setters, like:

Organization org = new Organization();
org.setCreatedAt(...);   // ← now it fails if setCreatedAt is private
org.setName(...);

⚠️ So if createdAt or any other field lacks a public setter, MapStruct can’t write to it anymore, hence the error:

Property "createdAt" has no write accessor in Organization.
