I have a Kotlin data class:
data class InterviewCreation(
val candidateId: String,
val offerId: String,
val startingDateTime: Long,
val duration: Long,
val location: String,
val description: String?
)
and a Mapper class (in Java) that starts like this:
public InterviewCreationViewModel toViewModel(InterviewCreation newInterview, String candidateName, String candidatePhotoUrl) {
String description = newInterview.getDescription();
String location = newInterview.getLocation();
long duration = newInterview.getDuration();
...
}
When running Lint, it crashes in the Mapper class
ECJ compiler crashed processing .../InterviewCreationViewModelMapper.java
java.lang.NullPointerException

And then it generates a lint report with a lot of false positives (I guess it's just not working right after the exception).
I've tried several things:
Obviously, none of these solutions is the desired one, but at this point I'm quite desperate. My two main options are stop using Lint or Kotlin.
Any suggestion is welcome.
Finally found the source of the problem.
The crash is because the whole class was invoked from a lambda, and retrolambda and lint are not friends.
I moved the whole lambda call to a method and it works.
