Kotlin + hilt error. [Hilt] and java.lang.reflect.InvocationTargetException (no error message)

Question

I have a problem with my hilt injection. Recently I started learning Kotlin and Hilt for my project. I watched some tutorials and afterwhile tried to write my own code

My build.gradle

    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "com.google.dagger:hilt-android-gradle-plugin:2.28.3-alpha"
        classpath 'com.google.gms:google-services:4.3.8'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

    }
}

allprojects {
    repositories {
        google()
        mavenCentral()

    }
}

And this one build.gradle

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            debuggable true
            signingConfig signingConfigs.config
        }
        debug {
            signingConfig signingConfigs.config
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

kapt 'androidx.hilt:hilt-compiler:1.0.0-alpha02'


}

I have a java.lang.reflect.InvocationTargetException (no error message) error And just one message in console This one message

Whats wrong? I read a lot of suggestions but none of them helped

Injection code

Answer 1

Did you add hilt-android-gradle-plugin to your project's root build.gradle file? This is how my gradle looks like:

plugins {
   id 'com.android.application'
   id 'kotlin-android'
   id 'kotlin-kapt'
   id 'dagger.hilt.android.plugin'
   id 'kotlin-parcelize'
}

Answer 2

Your classpath version should be the same as these two

implementation "com.google.dagger:hilt-android:2.28-alpha"
kapt 'com.google.dagger:hilt-android-compiler:2.28-alpha'

If it still doesn't work. Try to update all your hilt related to the lastest version, and make sure change your kotlin_version to 1.4.32. If you want to see the changes on hilt check out this: https://github.com/google/dagger/releases
