1.1.5 to 1.2.1 Migration - arrow.resilience.Schedule causes 'bad class file' error in Dagger KSP

[postfixNotation]

I migrated to the latest version of Arrow which made me add io.arrow-kt:arrow-resilience to use the Schedule class.
The import statement therefore changed from arrow.fx.coroutines.Schedule to arrow.resilience.Schedule and also arrow.fx.coroutines.retry to arrow.resilience.retry.

I'm using Dagger KSP version 2.49 and KSP version 1.9.21-1.0.16

When I build the module I get the following error message:

C:\Users\Me\AndroidStudioProjects\MyApp\app\build\generated\ksp\debug\java\com\...\dependencyinjection\app\AppModule_SomeClassFactory.java:5: error: cannot access SomeClass
import com.somepackage.SomeClass;
                                ^
  bad class file: C:\Users\Me\AndroidStudioProjects\MyApp\app\build\tmp\kotlin-classes\debug\com\...\SomeClass.class
    undeclared type variable: Input
    Please remove or make sure it appears in the correct subdirectory of the classpath.
C:\Users\Me\AndroidStudioProjects\MyApp\app\build\generated\ksp\debug\java\com\...\dependencyinjection\app\AppModule_SomeClassFactory.java:32: error: cannot find symbol
public final class AppModule_SomeClassFactory implements Factory<SomeClass> {
                                                                            ^
  symbol: class SomeClass
C:\Users\Me\AndroidStudioProjects\MyApp\app\build\generated\ksp\debug\java\com\...\dependencyinjection\app\AppModule_SomeClassFactory.java:67: error: cannot find symbol
  public SomeClass get() {
         ^
  symbol:   class SomeClass
  location: class AppModule_SomeClassFactory
C:\Users\Me\AndroidStudioProjects\MyApp\app\build\generated\ksp\debug\java\com\...\dependencyinjection\app\AppModule_SomeClassFactory.java:81: error: cannot find symbol
  public static SomeClass someClass(AppModule instance,
                ^
  symbol:   class SomeClass
  location: class AppModule_SomeClassFactory

So actually I cannot fully migrate from 1.1.5 to 1.2.1 using the lastest APIs/import statements.

Hi! Sorry for taking such a long time. This kind of problems usually happen when the names of type parameters do not coincide with the ones in the class. So I would like to ask some further question: how is the Schedule declared in your code?

[postfixNotation]

This is one of two declaration variants in my code:

@OptIn(ExperimentalTime::class)
    private val retryPolicy = Schedule
        .exponential<Throwable>(10.milliseconds)
        .whileOutput { it < 3.seconds }

I know whileOutput was replaced with doWhile.

This is one of some use case variants in my code:

operator fun invoke(): Resource<SomeClient> {
        return resource(
            { retryPolicy.retry { someClientConnected() } },
            { someClient, _ -> someClient.endConnection() }
        )
    }

Hope this helps somehow!

It seems that there might be some problems because of incompatibilities between kapt and newer Kotlin versions. The solution seems to be to migrate to KSP-based Dagger. @postfixNotation could you maybe try it and report back?

[postfixNotation]

Hi @serras,
I just double-checked. I'm using the most recent Dagger KSP and KSP plugin versions. None of the libraries I use for my module use KAPT. However, if I remove apply plugin: 'kotlin-kapt' from my app modules gradle file, there's an error message.

Dagger KSP:

implementation "com.google.dagger:dagger:$dagger_version"
ksp "com.google.dagger:dagger-compiler:$dagger_version"

Version numbers:

dagger_version = '2.50'
ksp_plugin_version = '1.9.22-1.0.17'

I tried to migrate yesterday again but I still get the same error message. I might be migrating from Dagger back to pure DI since Dagger won't become multiplatform in the foreseeable future. I also watched your keynote about context receivers which was pretty impressive.

@postfixNotation has this improved with 1.2.4?

@serras unfortunately it didn't.
