Broken scan of annotated elements for KMP app modules since KSP2 (After 2.1.20-1.0.31) - Impact Koin Annotations framework

[arnaudgiuliani]

Hello,

I'm maintaining the Koin framework. The Koin Annotations project uses the KSP project for annotation processing.

We use Resolver.getDeclarationsFromPackage() to scan annotations from other modules. It works in KSP 2.3.1 & Android applications.
For KMP apps, it stops working since 2.1.20-1.0.31 & KSP1.

When switching to KSP2, other modules' annotations are not seen from the commonMain task. Seems to appear in the android detected element, where it should not (I'm scanning an element declared in commonMain generation).

This project uses KSP. The data module should allow to scan external module and associate them. The Data Module is not detected since KSP2 version.

To look at it in the KSP2 issue, update the attached project with:

// libs.version.toml

koin-annotations = "2.3.0"
ksp = "2.3.1"

// gradle.properties
ksp.useKSP2=true

We are quite stuck on it:

• Modules discovery doesn't work for KSP later than 2.1.20-1.0.32 in multi-module KMP project InsertKoinIO/koin-annotations#312
• KOIN_CONFIG_CHECK Fails to Discover Included Modules from Other Gradle Modules InsertKoinIO/koin-annotations#310 (comment)

Thanks, let me know how I can help solve it.
