Android Studio Kotlin Room database error

Issue

While running my application I get this error (as well as 6 other similar errors) and changing the room version in my code to 2.3.0 or 2.2.3 doesn't fix it.

1: Task failed with an exception.

• What went wrong: Execution failed for task ':app:checkDebugAarMetadata'.

Could not resolve all files for configuration ':app:debugRuntimeClasspath'. Could not find androidx.room:room-coroutines:2.4.0. Searched in the following locations: - https://dl.google.com/dl/android/maven2/androidx/room/room-coroutines/2.4.0/room-coroutines-2.4.0.pom - https://repo.maven.apache.org/maven2/androidx/room/room-coroutines/2.4.0/room-coroutines-2.4.0.pom - https://jcenter.bintray.com/androidx/room/room-coroutines/2.4.0/room-coroutines-2.4.0.pom Required by: project :app

Here is my Project Build.Gradle:

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

Solution

I see you've commented room-ktx and added the room-coroutine

From room Version 2.1.0-alpha05 the artifact room-coroutines has been renamed to room-ktx following the same naming as other androidx artifacts.

So please use room-ktx instead of room-coroutines

//...

//room dependencies
implementation "androidx.room:room-ktx:$$rootProject.roomVersion"
implementation "androidx.room:room-runtime:$$rootProject.roomVersion"
kapt "androidx.room:room-compiler:$$rootProject.roomVersion"
androidTestImplementation "androidx.room:room-testing:$rootProject.roomVersion"

//...
