Migrating from Mapstruct 1.3.1 -> 1.4.1,
I have an annotation:
@Qualifier
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.SOURCE)
public @interface ElementToList {
}
And implementation
@Component
public class ElementToListUtil {
@ElementToList
public <T> List<T> first(T in) {
List<T> list = new ArrayList<>();
if (in != null) {
list.add(in);
}
return list;
}
}
and a tag on my mapping:
@Mapping(source = "blah", target = "fooArray", qualifiedBy = ElementToList.class)
This used to work, but now it is breaking with:
error: Qualifier error. No method found annotated with: [ @ElementToList ]. See https://mapstruct.org/faq/#qualifier for more info.
^
Can't map property "Foo foo" to "List<bar> barArray". Consider to declare/implement a mapping method: "List<bar> map(foo value)".
Am I missing something?
