When I upgrade my project to Kotlin 2.0.0-Beta4, I get the following from dependencyUpdates:

I don't get the errors with Kotlin 1.9.22: https://github.com/sdkotlin/sd-kotlin-talks/tree/a412bc0b6c80436a31dad58f51608c1cd70da170

Here is one of the --info details (the rest appear to be similar):

For some reason it wants the sourcesElements variant, but the authors decided not to publish that in their gradle module metadata. For example in my project's module metadata,

"name": "sourcesElements",
  "attributes": {
    "org.gradle.category": "documentation",
    "org.gradle.dependency.bundling": "external",
    "org.gradle.docstype": "sources",
    "org.gradle.usage": "java-runtime"
  },

For some reason the dependency did not include that in their module metadata.

I guess Kotlin multi-platform needs the sources and since those are not available in the metadata, it fails? They are included on the repository, though. This is more of a Gradle team question, as module metadata is confusing and the Kotlin tends to do odd things that are inconsistent with the ecosystem. I'm not the one capable of debugging this knot.

I retested with Gradle 8.7 and Kotlin 2.0.0-RC1. No significant change.

@ben-manes, Do you have a Gradle contact you'd typically reach out to for the sort of help you mention above? I can reference this in the #eap channel of the Kotlin Slack (they are asking for 2.0.0 RC testing feedback there), but I'm wondering if this isn't more of a Gradle than Kotlin issue.

[ben-manes]

I don't have one. I have simply been a nuisance for them since early years so interacted with many on their team. If one of their devs feels generous then they'll step in and help.
