The official documentation can be found here.

Android Studio – Execution failed for task ':app:kaptDebugKotlin' – Error Occurs while using Hilt

Added hilt dependencies:

Build.gradle(project)

def hilt_version = "2.38.1"
classpath "com.google.dagger:hilt-android-gradle-plugin:$hilt_version"

Build.gradle(app)

plugins {
 id 'dagger.hilt.android.plugin'
 ....
 }

....

dependencies {
implementation "com.google.dagger:hilt-android:2.38.1"
kapt "com.google.dagger:hilt-compiler:2.38.1"
 .......
 }

I also have a global application class:

MyApplication.kt

@HiltAndroidApp
class MyApplication : Application()

In my manifest:

Manifest.xml

<application
    android:allowBackup="true"
    android:name=".global.MyApplication"/>

Now, I create a module

NetworkModule.kt

@Module
@InstallIn(SingletonComponent::class)
class NetworkModule {

}

I get error when I run my code:

**Execution failed for task ‘:app:kaptDebugKotlin’.

A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
java.lang.reflect.InvocationTargetException (no error message)**

When I remove these:
@Module() and @InstallIn()

The error goes away…

what could be the problem? The error shown to me is not informative at all.

    So, it appears there is an issue integrating Hilt while targeting version 31 (Android 12).

    When I had:

    compileSdkVersion 31
buildToolsVersion "31.0.0"

defaultConfig {
   minSdkVersion 21
   targetSdkVersion 31
}

    The error appears...

    but when I changed to:

    compileSdkVersion 30
buildToolsVersion "30.0.3"

defaultConfig {
   minSdkVersion 21
   targetSdkVersion 30
}

    It starts working, without that error..

    Something wrong with integrating Hilt while targeting android 12 (likely)

    I Upgraded my project to Java 11 in the module gradle file.

    android {
compileSdkVersion 31
buildToolsVersion "30.0.2"

compileOptions {
    sourceCompatibility 11
    targetCompatibility 11
}

kotlinOptions {
    jvmTarget = "11"
}

    And I updated to the latest gradle plugins

    enter image description here

    And made sure the project points to gradle jdk11

    Keeping latest updated dagger hilt dependencies solved my problem.

    plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
id 'kotlin-kapt'
}

 //dagger 
    implementation 'com.google.dagger:dagger:2.40.5'
    kapt 'com.google.dagger:dagger-compiler:2.40.5'

    Build for targetSdkVersion 31 works fine with version 2.42 (jvmTarget, sourceCompatibility and targetCompatibility 1.8).
    Versions before 2.42 failed to build successfully.
