IssueTracker

Sorry, no mayor update. We are trying to figure out a better way for connecting runtime code with the generated database class such that referencing the generated instantiateImpl() is avoided. But since there is no reflection in native-land our options are limited.

Note that the instantiateImpl is generated in the same package as the @Database annotated class, so you might need an import if used from a different package: import <database-package>.instantiateImpl

However, most of the time if instantiateImpl() can't be resolved then it is a signal that Room's annotation processor is not being properly applied. Due to KMP and its multiple targets there is no easy-way (single line) way of applying the processor (without creating some helper of course). Also the way K2 / KSP2 behave with regards to KMP changed (see New Multiplatform Processing Scheme ) which means that if in KSP1 you applied the processor to all your 'end-targets' you could reference generated APIs from common code, but with KSP2 that is no longer the case and you need to apply the processor only to the common source set, assuming your @Database definition is in the common source set and then reference common generated code from the other non-common sets.

Adding

    sourceSets.commonMain {
        kotlin.srcDir("build/generated/ksp/metadata")
    }

Did the trick

You can build with Kotlin 2.0 by implementing the following code. You need to override the clearAllTables method.

• https://github.com/cvivek07/KMM-PicSplash/blob/main/composeApp/build.gradle.kts
• https://github.com/cvivek07/KMM-PicSplash/blob/main/composeApp/src/commonMain/kotlin/database/AppDatabase.kt

I was not able to replicate success in Kotlin 2.0 / KSP2 using the technique created by cvivek07. Also not successful with using the aforementioned code:

sourceSets.commonMain {
        kotlin.srcDir("build/generated/ksp/metadata")
    }

I can build successfully on Android or Native Kotlin, but not iOS.

I made a comment on a KSP bug which I think is causing this issue: https://github.com/google/ksp/issues/1940#issuecomment-2200514160

In the meantime you can workaround this with the following changes:

1. Apply the processor to the metadata compilation only:

dependencies {
    add("kspCommonMainMetadata", libs.androidx.room.compiler)
}

2. Add a task dependency to the KSP metadata task:

tasks.withType<org.jetbrains.kotlin.gradle.dsl.KotlinCompile<*>>().configureEach {
    if (name != "kspCommonMainKotlinMetadata" ) {
        dependsOn("kspCommonMainKotlinMetadata")
    }
}

3. Add the metadata generated sources to the other targets:

kotlin {
    sourceSets {
        commonMain {
            kotlin.srcDir("build/generated/ksp/metadata")
        }
    }
}

Note that the above workaround makes sense as long as you have your @Database in the common source sets. With the workaround you might encounter the following bug: https://issuetracker.google.com/348166275, to workaround that bug too declare a new interface with a empty default implementation of clearAllTables(), like this:

// Due to https://issuetracker.google.com/348166275
interface ClearAllTablesWorkaround {
    fun clearAllTables(): Unit {}
}

@Database(...)
abstract class TheDatabase : RoomDatabase() {
    // ...

    override fun clearAllTables() {
        super.clearAllTables()
    }
}

Hey all, we are thinking of making some API changes to fix this issue, support Kotlin 2.0 and avoid the workaround in https://b.corp.google.com/issues/342905180#comment12.

First and foremost, we still expect the processor to be applied to all end targets (iosX64, linux64, iosArm64, etc) and not the common compilation. Second, we'll remove the need to use the generated extension function instantiateImpl() and instead it will be replaced by user defined code, which helps avoid the red lines in the IDE and the confusion of referencing a to-be-generated function.

The setup would look like this (new API names are all TBD):

1. Define an expect object that will know how to build the database

// src/commonMain

expect object MyDatabaseCtor : RoomDatabaseConstructor<MyDatabase>

2. Link the object with the @Database declaration by using a new annotation

// src/commonMain

@Database(...)
@ConstructedBy(MyDatabaseCtor::class) // NEW
abstract class MyDatabase : RoomDatabase

3. Build a new database instance as usual but without passing a factory

// src/iosMain

fun createNewDatabase(path: String) = 
    Room.databaseBuilder<AppDatabase>(name = path)
        .setDriver(BundledSQLiteDriver())
        .setQueryCoroutineContext(Dispatchers.IO)
        .build()

A prototype of this has been implemented but not released, just sharing it here for early feedback. Thanks!

The next release of Room will contain the updated strategy for initializing Room in a KMP project, if you are eager to validate it you can do so with snapshot builds from https://androidx.dev/

It should be noted the the actual implementations of the RoomDatabaseConstructor expects will be generated by KSP. Warnings/errors can be ignored, at least until after you do a rebuild.

The 3rd step is specifically for the ios (or apple) side of things, no changes are needed for the android equivalent.

And I ran into build cache/ksp issues and had to do a full clean/rebuild.

Hi! I'm still waiting for a quick solution to the problems generated in iOS

This is my data:

My db:

package features.configIni.data.database

import androidx.room.ConstructedBy import androidx.room.Database import androidx.room.RoomDatabase import androidx.room.RoomDatabaseConstructor

@Database( entities = [ WebServiceRoom::class ], version = 1 ) @ConstructedBy(WebServiceDatabaseConstructor::class) abstract class WebServiceDatabase: RoomDatabase() { abstract fun webserviceDao(): WebServiceDao }

expect object WebServiceDatabaseConstructor : RoomDatabaseConstructor<WebServiceDatabase>

const val DATABASE_NAME = "webService.db"

On Android, everything works fine but on iOS I get the error:

Expected WebServiceDatabaseConstructor has no actual declaration in module MatchAcademico:composeApp for Native

when according to the official doc it does not require me to set the actual declaration

I was able to build both Android/iOS with room = "2.7.0-alpha06".

I had to change composeApp/build.gradle.kts.

Solution

// libs.versions.toml

[versions]
kotlin = "2.0.10"
roomVersion = "2.7.0-alpha06"
sqlite = "2.5.0-alpha06"
ksp = "2.0.0-1.0.21"

[libraries]
androidx-room-compiler = { module = "androidx.room:room-compiler", version.ref = "roomVersion" }
androidx-room-runtime = { module = "androidx.room:room-runtime", version.ref = "roomVersion" }
sqlite-bundled = { module = "androidx.sqlite:sqlite-bundled", version.ref = "sqlite" }

[plugins]
room = { id = "androidx.room", version.ref = "roomVersion" }
ksp = { id = "com.google.devtools.ksp", version.ref = "ksp" }

// composeApp/build.gradle.kts

import org.jetbrains.kotlin.gradle.ExperimentalKotlinGradlePluginApi
import org.jetbrains.kotlin.gradle.dsl.JvmTarget
import java.util.Properties

plugins {
    ...
    // room
    alias(libs.plugins.ksp)
    alias(libs.plugins.room)
}

kotlin {
    ...
    sourceSets {
        ...
        iosMain {
            // To provide RoomDatabaseConstructor actual declaration
            kotlin.srcDir("build/generated/ksp/metadata")
            dependencies {
                ...
            }
        }
    }
}

dependencies {
    ...
    // Room
    add("kspCommonMainMetadata", libs.androidx.room.compiler)
    add("kspAndroid", libs.androidx.room.compiler)
}

room {
    schemaDirectory("$projectDir/schemas")
}

Create the following classes according to the official documentation.

https://developer.android.com/kotlin/multiplatform/room#defining-database

• shared/src/commonMain/kotlin/Database.kt
• shared/src/androidMain/kotlin/Database.kt
• shared/src/iosMain/kotlin/Database.kt

Build

1. Android Studio > Build > Clean Project
2. Android Studio > Build > Rebuild Project

Since this have changed a between alpha05 and alpha06 (and alpha07), please double check your build Gradle file configuration.

1. Please apply it to all your 'end' targets (this list is exhaustive but only use the ones relevant to your project):

dependencies {
    // Android
    add("kspAndroid", libs.androidx.room.compiler)
    // JVM (Desktop)
    add("kspJvm", libs.androidx.room.compiler)
    // Linux
    add("kspLinuxX64", libs.androidx.room.compiler)
    add("kspLinuxArm64", libs.androidx.room.compiler)
    // Mac
    add("kspMacosX64", libs.androidx.room.compiler)
    add("kspMacosArm64", libs.androidx.room.compiler)
    // iOS
    add("kspIosSimulatorArm64", libs.androidx.room.compiler)
    add("kspIosX64", libs.androidx.room.compiler)
    add("kspIosArm64", libs.androidx.room.compiler)
}

Note that applying the processor to the kspCommonMainMetadata should not be needed.

2. Do not manually add KSP generated sources from other targets:

// DO NOT DO THIS
iosMain {
   kotlin.srcDir("build/generated/ksp/metadata")
}

This just leads to errors due to the differences of generated code between the platforms, which is why its important that on step 1 the Room KSP processor is applied to all targets that will use the common sources set where the @Database is defined.

3. Do not declare explicit task dependencies:

// DO NOT DO THIS
kotlin.sourceSets.commonMain {
  tasks.withType<KspTaskMetadata> {
    kotlin.srcDir(destinationDirectory) 
  }
}

Declaring direct dependencies and adding generated sources by KSP is a red flag, these where workarounds from alpha05 that shouldn't be needed with the newer @ConstructedBy strategy in alpha06.

4. Do not create the actual of the expect object class that implemented RoomDatabaseConstructor

// shared/src/commonMain/kotlin/Database.kt
expect object MyDatabaseCtor: RoomDatabaseConstructor<MyDatabaseCtor> {
  fun initialize(): MyDatabaseCtor
}

// shared/src/nativeMain/kotlin/Database.kt
// DO NOT DO THIS
actual object MyDatabaseCtor: RoomDatabaseConstructor<MyDatabaseCtor> {
  fun initialize(): MyDatabaseCtor { ... }
}

5. Make sure Kotlin version matches KSP version, i.e. if using Kotlin 2.0.10 then use KSP 2.0.10-1.0.24

6. If using Kotlin 2.x then the kotlin.native.disableCompilerDaemon = true is not needed and can lead to another issue (https://youtrack.jetbrains.com/issue/KT-69523).

7. If you are using the Compose Gradle Plugin and Room Gradle Plugin along with Kotlin 2.0 then you might see a separate issue regarding the plugins along the lines of Cannot change attributes of configuration ':<project>:debugFrameworkIosX64' after it has been locked for mutation, the workaround is to remove the Room Gradle Plugin and configure the schema directory via KSP arguments, see https://issuetracker.google.com/343408758

8. If you had the workaround for clearAllTables(), please remove it, it is no needed since Room is being applied to 'end' targets.

Feel free to comment even if the steps mentioned here don't work for you.

I just followed the suggestions of da..@google.com on Aug 11, 2024 10:20AM, and modified my gradle, as well as not creating the 'current' of the 'expect object' and the only error I'm getting from XCode, since on Android everything works fine is the following:

null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl

These are my classes

@Database( entities = [ WebServiceRoom::class ], version = 1 ) @ConstructedBy(WebServiceDatabaseConstructor::class) abstract class WebServiceDatabase: RoomDatabase() { abstract fun webserviceDao(): WebServiceDao }

expect object WebServiceDatabaseConstructor : RoomDatabaseConstructor<WebServiceDatabase>

const val DATABASE_NAME = "webService.db"

Another important thing is that kotlin.native.disableCompilerDaemon = true is not needed when using Kotlin 2.0.10, having it enable will lead to a different issue: https://youtrack.jetbrains.com/issue/KT-69523

Thank you very much for the prompt response, I really appreciate it!

I corrected your observations and I still have the same error in iOS Xcode,these are the logs I receive when I do the clean rebuild. I attached two images for a better look. Thanks for the support.

Thanks! These steps helped me fix Android and iOS. JVM is giving issues: Configuration with name 'kspJvm' not found.

re comment#32: Using Room is a library is about the same as using it in an application, the library ships the common code and the platform specific one that Room generates. I'll try to create a small sample app to demostrate it is possible.

re comment#34: In the stacktrace is shows KSP is crashing very early during Room annotation processing, please file a new bug as your issue is not quite related to the original issue described here.

e:file:///Users/..../kmp_project/zdckey_core/src/commonMain/kotlin/com/..../zdckey_core/data/database/ZDCKeyCoreDatabase.kt:21:8 Object 'ZDCKeyCoreDatabaseConstructor' is not abstract and does not implement abstract member 'initialize'.

Buddy. maybe you have some erros in ZDCKeyCoreDatabase.kt. You should not directly implement SDCKeyCoreDatabaseConstructor. You let it be just expect object.

Can you upload the declaration of SDCKeyCoreDatabase and implementation (in your case, it looks like you implement actual object) of ZDCKeyCoreDatabaseConstructor?

can I ask what proof_1.png source is located in? It should be in commonMain. If you can find the auto-generated actual object, can you upload?

The following release(s) address this bug.It is possible this bug has only been partially addressed:

I hope it serves as guidance, otherwise without a small repro project it is hard for us to point you in the right direction to fix your issue. Let me know if it is helpful.

In my opinion.. your compiler version doesn't support actual / expect. Can you check your Kotlin, KSP, Compose Version and talk to me?

After following all the guidance and checking the sample project I'm still getting: Object 'MyDatabaseCtor' is not abstract and does not implement abstract member 'initialize'

comment#43 When running the app, it runs without any issues, and the build is successful. However, when I try to rebuild the project either through Build > Rebuild Project or by running ./gradlew build, I encounter the same error @vi...@gmail.com is getting.

I have a similar error like yours when rebuild gradle.

'actual object AlarmDatabaseCtor : RoomDatabaseConstructor<AlarmDatabase>' has no corresponding expected declaration

However it works without error at my database.

So it seems the issue is when either running ./gradlew build or via Build -> Rebuild Project in the IDE. This is important information since those actions tend to build 'too many things'. Specially it tries to build common source set in isolation (compileCommonMainKotlinMetadata) which is a grey area in Kotlin right now, due to the expect / actual compilation model it is not possible to publish a 'common-only' library that has expect / actual as consumers can't contribute to those, i.e. you always publish -common along side a platform.

I agree building via those two actions is broken. But are they hindering the rest of your project if iOS (via XCode), JVM Desktop (via ./gradlew composeApp:run) and Android (via Android Studio) launch and work as expected? Or are they preventing you from publishing a library?

If it is still valuable to you to have a successful build via ./gradlew build then we actually just made a fix for this (see https://issuetracker.google.com/359631627) that will be in the next alpha release, the gotcha is that you need to declare the initialize override function in the expect object and then the generated code will also include the actual modifier. You can try this right now with a snapshot version of Room (see https://androidx.dev/). Here is a version of the sample project using the snapshot and with a working ./gradlew build containing the fix in b/359631627): https://github.com/danysantiago/RoomKmpLibraryExample/compare/main...snapshot

In my case, run via Android Studio, run via Xcode, Android CI (./gradlew build) and iOS CI (xcodebuild archive) are all broken with the same error. I've not managed to get a successful build to run with the latest alpha. It's a multi-module CMP project, it's virtually identical to your example project, in terms of Gradle and database initialisation, but with several entity types and DAOs added.

Edit: With snapshot, everything is working 👌🏻

re comment#19 Thank you for your work on this issue! It works in my situation.

Just one question, it seems to me that we can get XXDatabase info through the @Database annotation. I haven't seen the specific code, but I guess XXDatabase_Impl is also generated in this way? Is it possible generate expect object XXDatabaseConstructor : RoomDatabaseConstructor<XXDatabase> automatally without any intervention?

From issue 358913889 on 8/11/2024:

Update! Problems solved by doing things

1. disable room gradle plugin and rewrite ksp { .... } as you mentioned.
2. update kotlin and ksp version to 2.0.10

I think this is just temporary solution, however anyway it works now. I hope next version of room should be fixed ... :) thanks for your help!

Hi, I encountered a similar problem running KMM iOS build (room+ksp) and was able to resolve it by updating the dependencies.

room = "2.7.0-alpha08"
ksp = "2.0.20-1.0.25"

compose-plugin = "1.6.11"
kotlin = "2.0.20"
