Bug
BuilderProcessor declares @SupportedAnnotationTypes("*") — required so user-defined @SimpleBuilder.Template meta-annotations (arbitrary names) still reach the processor — and ends process() with return true.
return true claims all annotations in the round over the wildcard supported set, so every other annotation processor sharing the processor path is starved: e.g. when simple-builders-processor runs before mapstruct-processor, MapStruct never sees @Mapper and silently generates no mapper implementations. The same applies to any other processor (AutoService, Immutables, Lombok-as-processor, custom ones) ordered after it.
Fix
Always return false from process() — simple-builders never needs to claim annotations (other processors must still see them). Claiming a subset is not expressible: the boolean applies to the whole supported set, and * must stay for template discovery.
Found while working on the MapStruct SPI integration (#312).
