I know there are a few challenges with using Lombok, but since I do not use it myself I don't know exact details. For what it is worth, some other frameworks (auto-values, immutables) tend to have less problems as they handle code generation bit differently from Lombok. But one thing I would make sure is to use latest Jackson databind module (2.9.7 if possible) first. And after that if things still are not working, probably search for "jackson lombok constructor" or something -- I think there are many blogposts and SO matches that outline workarounds. -+ Tatu +- -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
