首先：
There's nothing wrong with IDEA, nor your dependencies or local maven caches, it's correctly identifying the mismatch.
Here's how to check:
1. Open class in question
2. Click "Show diff"
3. Choose "Ignore whitespaces and empty lines"
You can clearly see (ignoring JavaDoc and FQCNs) that the class file has extra checks included for the @NonNull annotated arguments. The import says lombok.NonNull, and the documentation shows this transformation will happen.
I guess the best course of action is either to ignore this warning or ask the project's maintainers to build the sources.jar from the lombok-processed source code if that's possible. I think they'll need to employ delomboking and this Maven plugin, but never built lombok code myself.

最后：
重启IDEA即可!
