How to resolve a Maven project?

Question

I have a Maven project using lombok and other external dependencies. I would like to add it to the resolver so that I can work on any of the generated Java files. So far I have tried JavaParserTypeSolver and JarTypeSolver and even tried delomboking the entire codebase, however even with that the external dependencies are not getting resolved.

I feel it's a very common setup (Maven project + lombok + other depencencies), is there a way to easily set-up the resolver for this?

In this example the library slf4j is not configured in the CombinedTypeSolver. So the class org.slf4j.LoggerFactory cannot be resolved.
