Hi,
with mapstruct-1.5.5.Final.jar and IntelliJ IDEA 2024.3.2 (Ultimate Edition),
I am facing the same issue as #93 https://github.com/mapstruct/mapstruct-idea/issues/93
@Mapping(target = "myFied", constant = "")
Type2 toType2(final Type1 myType1);
gives me the warning "Redundant default parameter value assignment"
