I try to update Koin from 3.5.6 to 4.0.0-RC1 (for validation purposes) in a project. But I got an error in compile time related to androidx.core.hardware.fingerprint.FingerprintManagerCompat.AuthenticationCallback.

The error is e: file:///Users/my_user/Documents/xpto/yz/project/core-auth/src/main/java/x/x/x/x/x/x/x/authmanager/domain/AuthManagerImpl.kt:221:5 'onAuthenticationSucceeded' overrides nothing.

How can I avoid it?

It seems you're using a transitive dependency from Koin which got updated in 4.0.0-RC1. You need to check the new contract for the method you're trying to override. It could be that the parameters have changed (type or even amount), return type

[Zacarias]

If for some reason you can't really use the newer transitive version that comes in Koin, then you could add a constraint in your build.gradle file so that you force the older version

[Zacarias]

This seems to be the latest contract. Maybe you're expecting this parameter (result) to be nullable, which is not the case anymore

[Pedro Francisco de Sousa Neto]

Thank you. I managed to work around this transitive dependency. And yes, was supporting the new one. That's not desired, but it worked as well. 🙃

Is it possible to avoid "leak" the dependency, @arnaud.giuliani?

[Pedro Francisco de Sousa Neto]

If no, I think we need to improve the docs as a requirement to use this version of koin.

Is it possible to avoid "leak" the dependency, @arnaud.giuliani?

it's an android dependency?

[Pedro Francisco de Sousa Neto]

Yes. I think koin is transiting android X library.

[arnaud.giuliani]

yes
