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.

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'

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

And made sure the project points to gradle jdk11 enter image description here

I'm trying to update android studio to Bumblebee's Android Studio version | 2021.1.1 RC 1

android {

    compileSdkVersion 31
    buildToolsVersion "30.0.3"

 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

gradle project

gradle module

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