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

Android studio gave the error:

Execution failed for task ':app:kaptDebugKotlin'.

I want to add in my project Kotlin Coroutines and use it with Room database. But after added all libraries I got this error. This is all information from the compiler.

I have identified, This is because of the annotation @Database. If I removed this annotation, the error don't appear, but Room is not working too.

My gradle file:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
//apply plugin: 'androidx.navigation.safeargs'

kotlin {
    experimental {
        coroutines 'enable'
    }
}

android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "com.bestcred.coursetthree"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        //vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    // Enables data binding.
    buildFeatures {
        dataBinding true
    }
}

dependencies {


    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    // Support libraries
    implementation "androidx.appcompat:appcompat:1.2.0"
    implementation 'com.google.android.material:material:1.2.0'
    implementation "androidx.fragment:fragment:1.2.5"
    implementation "androidx.constraintlayout:constraintlayout:2.0.0"

    // Android KTX
    implementation 'androidx.core:core-ktx:1.3.1'

    // Room and Lifecycle dependencies
    implementation "androidx.room:room-runtime:$room_version"
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    kapt "android.arch.persistence.room:compiler:$room_version"

    // Kotlin Extensions and Coroutines support for Room
    implementation "androidx.room:room-ktx:$room_version"

    // Coroutines
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutine_version"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$coroutine_version"

}

kotlin_version = "1.4.0"
room_version = "2.2.5"
coroutine_version = '1.3.9'

I update Room version and add Kotlin Coroutines. What's problem?enter image description here

Solution

  • You need change:

    kapt "android.arch.persistence.room:compiler:$room_version"

    to

    kapt "androidx.room:room-compiler:$room_version"
