error: [Hilt] Expected @AndroidEntryPoint to have a value

[s1nyx]

Hi,

I am having an issue with Hilt when i try to build my app on Android Studio.

I get this error :

/Users/sinyx/AndroidStudioProjects/MiniProjet/app/build/tmp/kapt3/stubs/debug/com/example/mini_projet/MainActivity.java:10: error: [Hilt] Expected @AndroidEntryPoint to have a value. Did you forget to apply the Gradle Plugin? (com.google.dagger.hilt.android)
public final class MainActivity extends androidx.activity.ComponentActivity {
             ^
  See https://dagger.dev/hilt/gradle-setup.html
  [Hilt] Processing did not complete. See error above for details.

I have @AndroidEntryPoint in my MainActivity.kt and @HiltAndroidApp in my ProjectApp.kt. So I don't understand what I am doing wrong.

More informations on the app: Github: https://github.com/s1nyx/supinfo-eng3-3andm-projet

Hi, @s1nyx , I think it's because the Hilt Gradle plugin is not applied. In your module build.gradle.kts you can try replacing this line:

id("com.google.dagger.hilt.android") version "2.48.1" apply false

to this:

id("com.google.dagger.hilt.android")

Hey, I just done it, after cleaning and rebuild I get this error Caused by: java.lang.IllegalStateException: The KSP plugin was detected to be applied but its task class could not be found.

Okay I found the issue.

In the Module build.gradle.kts : Renamed id("com.google.devtools.ksp") version "1.9.21-1.0.15" to id("com.google.devtools.ksp")

In the Project build.gradle.kts: Added id("com.google.devtools.ksp") version "1.9.21-1.0.15"

Works perfectly now :D Thanks !
