I'm using kapt for hilt and room. Whenever there is an error related to those libraries, kapt show me all errors in the generated Java code. How do I make it to show errors in Kotlin code instead? This is what it looks like in Android studio.
Just to clarify. It works fine for a valid code. But when there is a mistake (like a missing @Entity annotation on an actual entity class) I want it to point the error in Kotlin code, not in generated Java code.
Here is my project's build.gradle:
plugins {
id 'com.android.application' version '7.4.1' apply false
id 'com.android.library' version '7.4.1' apply false
id 'org.jetbrains.kotlin.android' version '1.6.10' apply false
id 'com.google.dagger.hilt.android' version '2.44' apply false
id 'org.jetbrains.kotlin.kapt' version "1.6.10" apply false
}
And the app's build.gradle:
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
id 'org.jetbrains.kotlin.kapt'
id 'com.google.dagger.hilt.android'

I've tried clearing Android Studio caches, rebuild and sync it a ton of times, lovered rooms version, but still no luck. It's basicaly just a project generated from Compose template. Plus I added room and hilt dependencies that I've added on top of it.
Looks like it's just the way KAPT works. Migrating to KSP helped, but I digged tons of google pages to find how to do it properly. The official doc (https://kotlinlang.org/docs/ksp-overview.html) only explains how to use it if you're a library developer. There is nothing there for mere mortals who just want to use KSP plugin for gradle. At least I could not find it there.
Anyway, here is project's build.gradle after migration to KSP (and to Kotlin 1.8.10):
plugins {
id 'com.android.application' version '7.4.1' apply false
id 'com.android.library' version '7.4.1' apply false
id 'org.jetbrains.kotlin.android' version '1.8.10' apply false
id 'com.google.devtools.ksp' version '1.8.10-1.0.9' apply false
id 'com.google.dagger.hilt.android' version '2.45' apply false
}

You must find matching ksp version here: https://github.com/google/ksp/releases
For example, if your kotlin-android plugin is 1.8.10, then you need to find ksp release that has first part matching 1.8.10 and the second part as high, as possible. In my case it's 1.8.10-1.0.9.
You also need to pay attention to this one (app's build.gradle):
composeOptions {
kotlinCompilerExtensionVersion '1.4.2'
}
Go to here https://developer.android.com/jetpack/androidx/releases/compose-kotlin#pre-release_kotlin_compatibility
and find the version that matches your kotlin version. In my case 1.4.2 is for kotlin 1.8.10.
This does not work for Dagger/Hilt becase they don't have support for KSP yet. Here is the issue: https://github.com/google/dagger/issues/2349
So you're basically stuck with Dagger/Hilt untill they add support for KSP.
Have fun.
