Hilt plugin problem with Android jetpack compose: "Expected @AndroidEntryPoint to have a value."

Question

I am using Hinl in my project and facing this error:

"Explain build error: [Hilt] Expected @AndroidEntryPoint to have a value. Did you forget to apply the Gradle Plugin? (com.google.dagger.hilt. android) See https://dagger.dev/hilt/ gradle- setup. html [1;31m[Hilt] Processing did not complete. See error above for details.[0m"

These are my plugins and dependencies:

plugins {
    alias(libs.plugins.android.application)
    alias(libs.plugins.jetbrains.kotlin.android)
    kotlin("kapt")
    id("com.google.dagger.hilt.android") version "2.51.1" apply false
}

Dependencies:

implementation(libs.hilt.android.v2511)
kapt(libs.hilt.compiler)
implementation(libs.androidx.hilt.lifecycle.viewmodel)
kapt(libs.androidx.hilt.compiler.v110)
implementation(libs.androidx.hilt.navigation.compose.v110)

And this is my MainActivity:

@AndroidEntryPoint
class MainActivity : ComponentActivity() {
    private val viewModel: WeatherViewModel by viewModels()
    private lateinit var permissionLauncher: ActivityResultLauncher<Array<String>>
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        permissionLauncher = registerForActivityResult(
            ActivityResultContracts.RequestMultiplePermissions()
        ) {
            viewModel.loadWeatherInfo()
        }
        permissionLauncher.launch(
            arrayOf(
                Manifest.permission.ACCESS_COARSE_LOCATION,
                Manifest.permission.ACCESS_FINE_LOCATION
            )
        )

        setContent {
            ComposeWeatherAppTestTheme {
            }
        }
    }
}

for new version kotlin, Hilt, Compose use this:

In .toml I use:

[versions]
kotlin = "2.0.0"
hiltAndroidCompiler = "2.51.1"
hilt = "2.51.1"
navigation-compose = "1.2.0"

[libraries]
hilt-android = { group = "com.google.dagger", name = "hilt-android", version.ref = "hilt" }
hilt-android-compiler = { module = "com.google.dagger:hilt-android-compiler", version.ref = "hiltAndroidCompiler" }
androidx-hilt-navigation-compose = { group = "androidx.hilt", name = "hilt-navigation-compose", version.ref = "navigation-compose" }


[plugins]
compose-compiler = { id = "org.jetbrains.kotlin.plugin.compose", version.ref = "kotlin" }
dagger-hilt-android = { id = "com.google.dagger.hilt.android", version.ref = "hilt" }
devtools-ksp = { id = "com.google.devtools.ksp", version = "2.0.0-1.0.24" }

in gradle Module:app use:

plugins {
    alias(libs.plugins.compose.compiler)
    alias(libs.plugins.dagger.hilt.android)
    alias(libs.plugins.devtools.ksp)
} 

android{
    composeOptions {
        kotlinCompilerExtensionVersion = "1.5.14"
    }
}
dependencies {
    //hilt
    implementation(libs.hilt.android)
    ksp(libs.hilt.android.compiler)
    implementation(libs.androidx.hilt.navigation.compose)
}

in gradle Top-level:

plugins {
    alias(libs.plugins.compose.compiler) apply false
    alias(libs.plugins.dagger.hilt.android) apply false
    alias(libs.plugins.devtools.ksp) apply false
}
