Mapstruct "Can't find related attribute"

Question

I have this Mapper class. I'm trying to combine all three objects into a single Dto for the view to use the Dto object:

@Mapping(source = "childSeat.id", target = "childSeatId")
@Mapping(source = "childSeatCol.id", target = "childSeatColId")
@Mapping(source = "dummyCollision.id", target = "dummyCollisionId")
ListeDePositionsUniquesDto toDTO(ChildSeat childSeat, ChildSeatCol childSeatCol, DummyCollision dummyCollision);

Here is a screenshot from the IDE: When I hover the source error it says: Can't find related attribute

Here are my dependencies:

I'm using Java 1.8, IntelliJ IDEA Ultimate.

Answer 1

The installation of Mapstruct Support plugin, which provides code completion and other features for projects that use Mapstruct, was the solution in my case.
