Answer 1

If you are using IDEA and Maven, you need to activate the IDE profile in IntelliJ. This is used for applying IDE-specific tweaks which currently only includes applying the MapStruct annotation processor.

Open the “Maven Projects” tool window (View -> Tool Windows), check the IDE maven profile to activate it

Answer 2

I had a similar problem, but using Maven and Eclipse. At the end I realized that I hadn't read well the bottom of the "Configuring your IDE" page from jHipster docs, which says about MapStruct, but I also had to add the target/generated-sources folder to my build path (as instructed on http://g00glen00b.be/mapstruct/ ).
