I am in the process of converting a kotlin application to kotlin multiplatform (anroid only for now to get through initial configuration) with room. This included moving to a libs.versions.toml file and KSP.
When compiling the app, I get the following error.
Any assistance you can provide would be greatly appreciated.
Build file 'C:\Users\georg\AndroidStudioProjects\PeepsConnection\build.gradle.kts' line: 26

a) Have a look at the KSP quickstart tutorial. The version to use is a whole other:
[versions]
# devtools_ksp = "1.5.30-1.0.0"
devtools_ksp = "2.0.0-1.0.23"
[plugins]
devtools_ksp = { id = "com.google.devtools.ksp", version.ref = "devtools_ksp" }
b) Load it in the root-project build.gradle:
plugins {
alias(libs.plugins.devtools.ksp) apply false
}
b) Apply it in the module build.gradle:
plugins {
alias(libs.plugins.devtools.ksp)
}
d) For multiplatform, the dependencies need to be defined differently.
kotlin {
sourceSets {
commonMain.dependencies {
ksp("androidx.room:room-compiler:2.7.0-alpha01")
}
androidMain.dependencies {}
iosMain.dependencies {}
}
}
e) The schema location also needs to be defined differently:
ksp {
arg("room.schemaLocation", "$projectDir/schemas")
}
f) In file settings.gradle, add this line:
kotlin.native.disableCompilerDaemon = true
See Room (Kotlin Multiplatform) for details; there's now also a bundled SQLite library for iOS.
And there's also a Migrate Room to Kotlin Multiplatform tutorial.
