Getting NoSuchFileException during incremental build

[kevinguitar]

Hey Zac!

We're getting this error constantly with an incremental build, is it an issue on the level of Anvil?

Few notes:

• We're using configuration cache
• We enabled kotlin.incremental, kotlin.incremental.usePreciseJavaTracking and kotlin.incremental.useClasspathSnapshot in gradle properties
• Happened in both hybrid (Dagger KAPT) and KSP only mode

Sorry I'm not sure what KSP is doing in this case. Can you file a bug on their issue tracker with a reproducible sample?

[kevinguitar]

Looks like it's the same issue here, it's related to KSP incremental
google/ksp#1678 (comment)

[kevinguitar]

I can confirm that the issue is gone after disabling ksp.incremental
