After switching to 8.11-milestone1 and enabling parallel CC + Project isolation + build cache (using the GitHub action), I strangely get

publish: UP-TO-DATE

when publishing to GitHub packages using

org.gradle.maven-publish

. I though publish should never up-to-date because it is a remote operation.

publish itself is a no-op IIRC, it only depends on the various publishThisToThatRepository tasks, so maybe the status is just reported differently

Thanks for the hint, a build scan was (as always) helpful. I refactored my build scripts and forgot to register the mavenPublication in the jvm modules (because it is done automatically by the Kotlin MPP plugin)...
