Hello everyone

Guys I am trying to use Room with Kotlin 2.0

I am getting:

e: [ksp] java.lang.NullPointerException: null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl
error: null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':composeApp:kspKotlinIosX64'.
> A failure occurred while executing com.google.devtools.ksp.gradle.KspAAWorkerAction
   > null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl

Double check you're not using KSP2 in your gradle properties

[Javokhir Akramjonov]

kotlin.code.style=official

#Gradle
org.gradle.jvmargs=-Xmx2048M -Dfile.encoding=UTF-8 -Dkotlin.daemon.jvm.options\="-Xmx2048M"

#Android
android.nonTransitiveRClass=true
android.useAndroidX=true

#MPP
kotlin.mpp.androidSourceSetLayoutVersion=2
kotlin.mpp.enableCInteropCommonization=true

#KMP
kotlin.mpp.androidGradlePluginCompatibility.nowarn=true

# Disabled due to <https://youtrack.jetbrains.com/issue/KT-65761>
kotlin.native.disableCompilerDaemon=true
ksp.useKSP2=true

# For KSP
DallowAllTargetConfiguration=false

my current gradle.properties

[chrisjenx]

ksp.useKSP2=false

[Javokhir Akramjonov]

thanks. But then

Cannot change attributes of configuration ':composeApp:debugFrameworkIosX64' after it has been locked for mutation

[chrisjenx]

that one I don't know, generally, gradle clean, gradle --stop, sync rerun

[chrisjenx]

esp when changing gradle versions/kotlin/kmp etc

[chrisjenx]

as they run cached compilers in the background which (don't always) get cleaned
