# koin

[Lena Stepanova]

Hi, I've spent the whole day trying to understand why I suddenly get org.koin unresolved error. I think, after I changed dependencies some time ago to io.insert-koin, the project kept working on cached libraries. Today I invalidate the caches and cannot use KoinComponent anymore. It's a Kotlin Multiplatform project.
I would really appreciate any help!

Funnily, the project builds and runs from develop branch, but doesn't from another working branch. And I'm sure I haven't done anything to koin or other dependencies there 🤯

Hi, did you reimport the project, clean your .gradle cache also ?

[arnaud.giuliani]

does it compile from terminal?

[Lena Stepanova]

What do you mean by reimporting the project? I tried cleaning the cache, the project, deleting gradle folder
./gradlew clean build fails with Unresolved reference: KoinComponent
However, the moment when I switch to an older branch, I can build and run it again

[arnaud.giuliani]

did you change the version, or did you just updated the groupId from org.koin to io.insert-koin ?

[arnaud.giuliani]

as it’s the same version, the API should stay the same

[Lena Stepanova]

Increased the version from 3.0.0-alpha-4 to 3.0.1

[arnaud.giuliani]

However, the moment when I switch to an older branch, I can build and run it again

ok, because the local build is still the same gradle config

[arnaud.giuliani]

ok, weird. You can even work with 3.0.2

[arnaud.giuliani]

your project was in 3.0.0 alpha?

[Lena Stepanova]

Yes, it was 3.0.0-alpha-4
Tried 3.0.2, but it's the error is the same

[arnaud.giuliani]

3.0.0 is quite “old”, and there were some breakings API. Put yourelf in 3.0.2

[arnaud.giuliani]

and perhaps try to remove import of Koin

[arnaud.giuliani]

and reimport things

[arnaud.giuliani]

Yep, this is it. Just reimport things. The KoinComponent was breaking in 2.2.2 and 3.0.0. It has been move to:

import org.koin.core.component.KoinComponent
import org.koin.core.component.inject

[arnaud.giuliani]

org.koin.core.component package

[Lena Stepanova]

Yep, I've changed the imports from org.koin.core to or.coin.core.component right after changing the groupId and the version

[Lena Stepanova]

I invalidated caches in the branch where I increased the version and get now the same error

[Lena Stepanova]

When I start typing import org... I don't even see the koin package suggestion

[Lena Stepanova]

But the libraries are there

[Lena Stepanova]

Tried again and it worked 😐 AS still shows koin as unresolved, but the project runs. I had such behaviour before, but this time was extremely weird. Anyway, thanks! @arnaud.giuliani

[arnaud.giuliani]

yes really weird, wha&t version of AS do you use?

[Lena Stepanova]

4.1 rc3 gradle 6.5 gradle plugin 3.6.3

[arnaud.giuliani]

I believe your gradle version can be a bit old (many meta data stuff in last 6.7 and other versions)

[arnaud.giuliani]

try with a recent AS 4.2 config if you can

[Lena Stepanova]

I'll give it a go when I have time 🙂 Upgrading the gradle plugin gave me other problems, so I decided to stick with what's working for now

[arnaud.giuliani]

there is some days like that 😄 good that you can continue despite those problems

[arnaud.giuliani]

KMM is sometimes a bit magical

[Lena Stepanova]

True 🙂
