I'm trying to build an ios project in Xcode that uses KMP, it uses a Build Phase script that runs:

cd "$SRCROOT/.."
./gradlew :shared:embedAndSignAppleFrameworkForXcode

This has been working fine. Then today, my build started failing with:

e: java.lang.NoClassDefFoundError: org.jetbrains.kotlin.resolve.calls.smartcasts.DataFlowInfo (initialization failure)

I'm not sure what this means, or how to fix it?
Has anyone else run into this?

From my experience, it can be one of two three things:
• Gradle Cache issue: run ./gradlew clean and try again running ./gradlew :shared:embedAndSignAppleFrameworkForXcode
• Check Kotlin Version Compatibility: Verify that the Kotlin version used in your shared module's build.gradle.kts (or build.gradle) file is compatible with the Kotlin Gradle plugin version.
• Xcode Version: When developing KMP project with support to any iOS target, always make sure that your Xcode version is compatible with KMP which can be found here https://kotlinlang.org/docs/multiplatform-compatibility-guide.html#version-compatibility

I've eliminated some variables ... I can't even do a gradlew clean in the Multiplatform project folder. I get the same error. So it's not an Xcode thing. I've double checked my kotling and plugin versions. those are good.

I'm not sure what's going on here

@Moussa Thanks for the tips. I have a fourth item to add to your list of possible things:

• Reboot your mac
🤦‍♂️ I rebooted, and my builds work great.
