Hi. Got this on my mac today:

Downloading Kotlin Toolchain distribution v0.12.1...

################################################################ 100.0%

ERROR: Checksum mismatch for /Users/jakub.g/Library/Caches/JetBrains/Kotlin/cli/download-file-64711.bin (downloaded from packages.jetbrains.team/maven/…/kotlin-cli-0.12.1-dist.tgz): expected checksum 614494004c77b917a6247c26fb62d767fb449b2467d6b226e949fa0f1350608a but got ce48f9401e26312e6cbca77177bc847ace33028db730028de46fbe6269abd0eb

(repeatable)

everything was working on my linux, i committed the new wrapper in my project, pushed and tried to pull and run on my macbook.

so I deleted kotlin wrapper files, ran kotlin update --create from my sdkman installation, and indeed:

is it possible that your install sets different sha256 on linux and on mac?

[joffrey]

It should not set different checksums, because it's the same JVM-based distribution on all OSes right now. However, doing kotlin update might actually give you a different version, which would have a different sha

[Jakub Gwóźdź]

i cannot reproduce it anymore, might've been some strange hiccup. is it possible that some update changed the version in wrapper, but not the sha fingerprint?

[joffrey]

Ok it's actually a very serious issue, thanks for noticing. For some reason our artifacts repo was not marked as immutable AND we had a bug in our CI that made it overwrite the publication when we ran it in a special mode to fix the SDKMAN stuff.

KTC-5888 kotlin-cli-0.12.1-dist.tgz was overwritten with a main-branch build; wrapper checksum check fails

🙇

I experience the same on Windows! My lesson starts in 5 minutes🫣

[Jakub Gwóźdź]

I'd say: remove the kotlin.bat file and reinstall

[joffrey]

I'm currently releasing 0.12.2 because dealing with the current state of 0.12.1 is a bit tricky and will take a little bit more time

[Jakub Gwóźdź]

or change the kotlin_cli_sha to the expected value

[joffrey]

@Jakub Gwóźdź while that works, you effectively get a recent dev version from main. So at that point you might as well kotlin update --dev

[Jakub Gwóźdź]

ah!

[joffrey]

0.12.2 should be out in ~10min (let's be conservative)

[Jakub Gwóźdź]

adventurous!

[joffrey]

0.12.2 is available now! Sorry for the inconvenience

[Paul at Avans Breda]

Can I update to this specific version?

[joffrey]

If you have a globally installed Kotlin Toolchain, kotlin update should work, but you can also do kotlin update --target-version=0.12.2.

[joffrey]

If your local Kotlin wrapper is broken because of the checksum, you can delete it and run the global kotlin update --create to re-create them in the latest (0.12.2) version, as described by Jakub as the first post of this thread.

[joffrey]

If you don't have a global installation at all, I would advise to just replace the wrapper by hand with kotl.in/cli.bat or kotl.in/cli.sh (depending on your OS) or use the installer command from our homepage.
