How to correctly add Room Persistence dependencies to my Jetack Compose Android app

I have been struggling to add Room dependencies for a couple of days now(not proud). There is always an error no matter what i try. I am not the most experienced though.

I added the below from the Android docs site.

`val room_version = "2.5.2"

implementation("androidx.room:room-runtime:$room_version")
annotationProcessor("androidx.room:room-compiler:$room_version")

//1
// To use Kotlin annotation processing tool (kapt)
kapt("androidx.room:room-compiler:$room_version")

//2
// To use Kotlin Symbol Processing (KSP) (2)
ksp("androidx.room:room-compiler:$room_version")

// optional - Kotlin Extensions and Coroutines support for Room
implementation("androidx.room:room-ktx:$room_version")`

All depencdencies can resolve except what is marked 1 & 2. For 1, i get Type mismatch. Required: KaptOptions Found: String

For 2, i get Unresolved reference: ksp

I added these to my plugins from searches i did but to no avail. ` id("com.google.devtools.ksp") version "1.8.21-1.0.11" kotlin("android")

// Apply the Room and Kotlin Kapt plugins
kotlin("kotlin-kapt")
id("androidx.room.room-compiler")`
Solution

  • What properly worked was following the migration guide at Migrate from kapt to KSP

    I used

    ksp("androidx.room:room-compiler:$room_version")

    Added the below to the project level build.grradle

    plugins {
id("com.google.devtools.ksp") version "1.8.10-1.0.9" apply false}

    Added the below to the module level build.gradle

    plugins {
id("com.google.devtools.ksp")}

    And remove everything added for the kapt
