Research direction

Reproduce the warning with the Kotlin @JvmRecord data class, Java record, and ServiceMapper examples from the issue, then compare the plugin's mapping analysis with MapStruct's result. Trace the inspection or mapping-resolution entry point that handles record properties. Done means the false absent-target-mapping warning no longer appears for this case while genuine warnings remain.

Written by the indexing model from the issue text.

Description

kotlin

If you have such data class:

@JvmRecord
data class Service(
    val serviceId: Long,
}

and such java record:

record Service2(
  long serviceId
) {}

and use them in mapping:

@Mapper
interface ServiceMapper {
  Service2 fromService(Service service);
}

Then plugin will false warn about absent target mapping, but MapStruct itself works well.
