Maybe not the right channel for this, but I was using an RC version of the Kotlin compiler and recently upgraded
In my project, I now get this error and can't seem to solve it, even if I delete /build

Compilation failed. Pre-release classes were found in dependencies.
Remove them from the classpath, recompile with a release compiler or use '-Xskip-prerelease-check' to suppress errors
Reason: Class is compiled by a pre-release version of Kotlin and cannot be loaded by this version of the compiler

I've set my Kotlin dependency version to 1.60.0, has anyone encountered this before?
Thank you 😃

What doesn't make any sense to me is why it would persist after deleting the build directory

Shouldn't that mean the next compilation is entirely fresh, from the currently installed version? 🤔

Perhaps you’re using a dependency compiled with a prerelease compiler?

[Gavin Ray]

That's what I thought too, if I look at the names of the classes they're all classes from inside the project though confusingly

[Gavin Ray]

Ah wait -- maybe IntelliJ has cached them somehow and is avoiding recompiling them because they haven't changed?

[wasyl]

If you’re using Gradle, there’s number of places stuff can be cached:
• gradle local and remote build caches (~/.gradle/cache/build-cache-1)
• module build directory <modulePath>/build
• project-level .gradle directory (./.gradle)
You can also force what should be a clean build by adding --rerun-tasks --no-build-cache and optionally --refresh-dependencies flags to ./gradlew invocation

Let me try with those Gradle flags, sounds like it might do the trick! Ty!

[Gavin Ray]

Damn, still no dice

[Gavin Ray]

Let me see if I can nuke every cache folder

[Gavin Ray]

Ah, it was because I had -Xcontext-receivers enabled which was marking the sources as prerelease 🙄
