Description
Referencing a target that does not exist results in a compilation error.
Therefore we should support the check of target properties (MapstructTargetReference) for that annotation.
interface FooMapper {
@Ignored(targets = "nonExistent") // mark this as unknown
CarDto map(Car car);
}
This should also work for nested properties like @Ignored(targets = "driver.name").
Beware that writing it as an array must also work:
@Ignored(targets = { "a", "b" })

Research direction
Start by locating MapstructTargetReference and the handling of targets in the @Ignored annotation. Verify unknown simple targets, nested properties such as driver.name, and array syntax with multiple targets; done means each invalid target is reported as a compilation error.
