🧵 Koin Compiler

I'm using Koin in a KMP project (Android + iOS + Desktop), and I have KSP because I'm also using Room, but not Koin Annotations.
I want to migrate to the new Koin Compiler. I followed the instructions, but I'm facing a compilation error when I try to build the project.
Any guess?

java.lang.NoSuchMethodError: 'org.jetbrains.kotlin.fir.declarations.FirNamedFunction org.jetbrains.kotlin.fir.plugin.SimpleFunctionBuildingContextKt.createTopLevelFunction(org.jetbrains.kotlin.fir.extensions.FirExtension, org.jetbrains.kotlin.GeneratedDeclarationKey, org.jetbrains.kotlin.name.CallableId, org.jetbrains.kotlin.fir.types.ConeKotlinType, java.lang.String, kotlin.jvm.functions.Function1)'

If I remove the alias(libs.plugins.koin.compiler.plugin), the project can build. But if will fails in runtime with:

kotlin.NotImplementedError: Error while using 'startKoin<T>()'. The Koin Compiler plugin is missing. Please fix your setup to use 'io.insert-koin.compiler.plugin' Koin Gradle Plugin.

It seems linked to incompatible version. Check you kotlin version, and if still not working, you may have another compiler that update under the hood the kotlin version. I have the same version incompatibility between Koin and Mokkery

[Pedro Francisco de Sousa Neto]

I'm using:

kotlin = "2.3.10"
kotlinx-coroutines = "1.10.2"

Which Kotlin version do you recommend?

[Joost Klitsie]

2.3.20-beta2

[Pedro Francisco de Sousa Neto]

I'm able to compile and run with the Kotlin version 2.3.20-Beta2 . Thanks!
Now I've another error, but it's because the project was a little bit old and I need to upgrade other stuff.
Thanks, folks!

[arnaud.giuliani]

2.3.20-beta1 is required. 2.3.20-beta2 is getting errors

[Pedro Francisco de Sousa Neto]

I'm able to build with 2.3.20-beta2 but I'm facing some issues, like the error bellow. But I think it could be something wrong with my migration from KSP to Compiler in a KMP project.

Caused by: org.koin.core.error.NoDefinitionFoundException: No definition found for type 'com.x.y.features.cards.register.repository.CardsRepository' on scope '['_root_']'. Check your Modules configuration and add missing type and/or qualifier!


But I will give a try with 2.3.20-Beta1!

[Pedro Francisco de Sousa Neto]

The error above was in runtime. Is it should be in compile time, right? Because now I'm using the Koin Compiler. 🤔

[arnaud.giuliani]

yeah, but perhaps some generation are not done. You can activate logs to see how it works

[Pedro Francisco de Sousa Neto]

It's working with 2.3.20-Beta1!!!!

For some reason, it is crashing (runtime) with a NoBeanDefFoundException in specific part of the project. I need to investigate it.

I'll give a try in Kotzilla Platform to get more insights. 🙂

[Pedro Francisco de Sousa Neto]

The class TagsRepository was in com.velantasistemas.money.features.database.repositories, then I moved it to com.velantasistemas.money.features.tags.repository.

So the app stops to crash in runtime because the DI module was in the same level (see the other screenshot).

The module:

@Module
@ComponentScan("com.velantasistemas.money.features.tags")
class TagsModule

But now my question is, why is it didn´t failed in compile time? 🤔

[arnaud.giuliani]

no compile time check yet

[Pedro Francisco de Sousa Neto]

Do you have an ETA?

[arnaud.giuliani]

Working on it 💪 🔥 Should have somthing soon
