Konsist causing some trouble when bumping to Kotlin 1.9.20: fix(deps): update kotlin monorepo to v1.9.20 - have you encountered this issue?

[igor.wojda]

I will investigate

[igor.wojda]

@Piotr Krzemiński It started working for me after adding testImplementation("org.jetbrains.kotlin:kotlin-compiler:1.9.20") dependency.

Branch renovate/kotlin-monorepo branch
File" library/build.gradle.kts

Please verify if this work for you

[igor.wojda]

It looks like kotlin:kotlin-compiler dependency is not added correctly to the test source set, however it is provided by Konsist.

This issue is under investigation
https://lemonappdev.atlassian.net/browse/KON-576

I am open for ideas here.

@Piotr Krzemiński I suspect this is a Kotlin regression bug. Here is the Kotlin ticket
https://youtrack.jetbrains.com/issue/KT-63187/Upgrade-from-1.9.10-to-1.9.20-breaks-the-project

[Piotr Krzemiński]

Ah, with the explicit dependency it works, but now my tests using com.github.tschuchortdev:kotlin-compile-testing:1.5.0 fail which is a separate issue. Looks like depending on libraries that depend on compiler's (internal?) API is problematic

[Piotr Krzemiński]

I'll try to figure it out and come back to you

I ended up with such change prior to bumping Kotlin to 1.9.20: chore(lib): switch from com.github.tschuchortdev:kotlin-compile-testing to dev.zacsweers.kctfork. In short, some other library depending on kotlin-compiler was messing something up, so I decided to switch to its fork that is better maintained and supports newer Kotlin versions. I still had to use the newest version of kotlin-compiler (testImplementation(kotlin("compiler"))). After this change, bumping Kotlin to 1.9.20 was simple

[igor.wojda]

thx for the info.
Can you drop a comment on the Kotlin ticket on what was core issue - perhaps they will be able to improve error handling on this int the future

Added comment to Kotlin ticket. I think we can consider this issue closed.

BTW this was an interesting one 🤓

[Piotr Krzemiński]

thanks, I still don't feel like we got to the very bottom of the problem (I haven't checked what version of kotlin-compiler the other library ingests), but thanks anyway for your assistance 🙂 I think the culprit here is unstable compiler's API, changing from release to release

[igor.wojda]

I have asked Kotlin team "if there is anything we can do about this issue to handle these mis matched dependencies in the future?" Let's observe this one

[igor.wojda]

BTW I am finding this lib quite interesting. I wonder what is you exact use case for it?

[Piotr Krzemiński]

thanks, please see the landing page in the docs, I think we've nailed it there: https://typesafegithub.github.io/github-workflows-kt/ - happy to clarify further 🙂
