Object with field name "setCode" throws => Unknown property "setCode" in result type - mapstruct

Question

We are using mapstruct to map objects. And in one of the case we have defined the mapping using #Mapping annotation like below:
#Mapping(source = "glSetCode", target = "setCode")
and we are getting error Unknown property "setCode" in result type.
Did you mean "null"?
The field setCode exists in the target object. Mapping other fields in the same way doesn't throw error.
We also use lombok and we have both annotation processors in our pom.xml

Did try changing the setCode to something else and it worked. But wanted to know the cause for why it is failing since changing field name will have to be updated in multiple mappers/areas.
