Plugin reports "Can't find related attribute" warning when using `source="."` #187

Closed Chessray closed 5 months ago

This style of mapping declaration leads to the warning "Can't find related attribute".

@Mapping(target = "value", source = ".")
WrapperObject convert(String rawId);

@Chessray the use of source = "." is not really documented properly. I think that it works by accident (even in the processor itself). I would instead do source = "rawId" here. Perhaps we need to have a warning or an error for this. in the INtelliJ plugin

So this is not intended to work in the Processor? That means I've been advising clients about an undocumented feature for years. 😬 The plugin displays a warning which seems to be intended then.
