binary-compatibility-validator Migrate to newer kotlin-metadata-jvm

Currently (https://github.com/Kotlin/binary-compatibility-validator/blob/29a83d78596bfdbc37f885da881edc40021eb073/gradle/libs.versions.toml#L18) BCV uses kotlinx-metadata-jvm 0.6.2. This version uses some obsolete APIs, and it is recommended to migrate to the latest stable version with a different package. Moreover, it is required to be able to read Kotlin 2.1 language version (to which master branch of Kotlin will be switched soon).

Changleg and migration guide are available here: https://github.com/JetBrains/kotlin/blob/75c87dd8585147b4abab2ac262fac84a037f07be/libraries/kotlinx-metadata/jvm/Migration.md#L1 https://github.com/JetBrains/kotlin/blob/75c87dd8585147b4abab2ac262fac84a037f07be/libraries/kotlinx-metadata/jvm/ChangeLog.md

It's relatively easy to update the code (see update-metadata-lib branch), but kotlin-metadata-jvm:2.0.0 will bring transitive dependency on stdlib:2.0.0, so https://github.com/Kotlin/binary-compatibility-validator/issues/208 needs to be done first.

org.jetbrains.kotlinx:kotlinx-metadata-jvm:0.6.2 will also no longer work with Kotlin 2.1.0, see https://github.com/kordlib/kord/commit/9a90ee0f5b669a017a0b04caf53eaee8fd02f9fe

@fzhinkin Is there a problem with releasing just update-metadata-lib? Kotlin master is already switched to 2.1

Jul 12 '24 13:07 sandwwraith

@sandwwraith, the issue with update-metadata-lib is that kotlin-metadata-jvm will bring the stdlib 2.0 as a dependency.

Jul 12 '24 13:07 fzhinkin

Huh, or I'm wrong and it won't be a problem. Let me check.

Jul 12 '24 13:07 fzhinkin

Ok, I'm wrong.

Jul 12 '24 13:07 fzhinkin

But isn't BCV itself using stdlib 2.0 already? 🤔

Jul 12 '24 13:07 sandwwraith

No, it's not.

Jul 12 '24 13:07 fzhinkin

Yeah, I was wrong. Opened the PR: #255. Once it is merged, a new version with Kotlin 2.1 support will be released.
