Guys, I am struggling on making my processor incremental. I am receiving some exceptions when modifying a dependency, sometimes it’s a NPE, sometimes it’s an ArrayOutOfBounds, but if I re-run everything executes just fine. I already tried to create the Dependencies instance by just adding the symbol.containingFile and also tried by adding all the files of the inherited interfaces. For more context, I am generating classes base on an annotated interface which can then inherit from other interfaces.

This is the stacktrace I’m receiving:

e: java.lang.NullPointerException
	at com.google.devtools.ksp.DepInvalidator.invalidate(Incremental.kt:663)
	at com.google.devtools.ksp.DepInvalidator.invalidate(Incremental.kt:655)
	at com.google.devtools.ksp.IncrementalContext.calcDirtySetByDeps(Incremental.kt:232)
	at com.google.devtools.ksp.IncrementalContext.calcDirtyFiles(Incremental.kt:363)
	at com.google.devtools.ksp.AbstractKotlinSymbolProcessingExtension.doAnalysis(KotlinSymbolProcessingExtension.kt:118)

Also I did check the logs in build/kspDirtySet.log and all the files are dirty, no idea why

ArrayIndexOutOfBoundsException

I am settings the Dependency.aggregating = true because my case is very similar to the first example here

Do you have a publicly reproducing example project? Your details are quite vague

[Ademir Queiroga]

Sorry about that… I’ll create a public repo with the code

Here it is: https://github.com/ademirqueiroga/modelize

If you compile once an then change any of the interfaces in the src/main/kotlin/sample/AppConfig.kt it gives an NPE

[Ademir Queiroga]

I even used some code @Zac Sweers wrote in the moshi KSP implementation, specifically the OriginatingKSFiles.kt file, to better resolve the dependencies but no luck

Not sure if there's any relation with https://github.com/google/ksp/issues/223#issue-776800945 as the AppConfig interface is in a different module...

Thanks for the bug report. This is a bug regarding with the interaction between incremental and multipleround processing. Will try to fix before next release.
