Inspection "Target property must not be mapped more than once" incorrectly flags multiple mappings to "."

[PRiewe]

If the target class includes properties from multiple source sub-classes then this mapping is legal:

  @Mapping(target = ".", source = "key")
  @Mapping(target = ".", source = "foo")
  @Mapping(target = ".", source = "bar")
  public abstract MyClass toMyClass (MyClassInternal internal);

It is only illegal if there is overlap in the properties (i.e. if MyClass has property X and both foo and bar contains X)

Thanks @PRiewe. This looks like a bug. Should be fixed in #242
