Hilt Unsupported metadata version in Kotlin

Question

I was tried to run my code in Kotlin 1.5.10 With plugin as

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

and dependencies as below

dependencies {
    ...
    //Dagger - Hilt
    implementation "com.google.dagger:hilt-android:2.33-beta"
    kapt "com.google.dagger:hilt-android-compiler:2.33-beta"
    implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"
    kapt "androidx.hilt:hilt-compiler:1.0.0-beta01"
    implementation 'androidx.hilt:hilt-navigation-compose:1.0.0-alpha01'

    implementation 'com.android.support:palette-v7:28.0.0'

When I migrate to kotlin_version = "1.5.10", it just errors out stating

error: [Hilt] Unsupported metadata version. Check that your Kotlin version is >= 1.0: java.lang.IllegalStateException: Unsupported metadata version. Check that your Kotlin version is >= 1.0 at dagger.internal.codegen.kotlin.KotlinMetadata.metadataOf(KotlinMetadata.java:206) at dagger.internal.codegen.kotlin.KotlinMetadata.from(KotlinMetadata.java:186) at java.base/java.util.HashMap.computeIfAbsent(HashMap.java:1133) ...

Can anyone help me? I spent a lot of time on it, your answer will help me a lot

Answer 1

Go to https://dagger.dev/hilt/gradle-setup check Hilt currently version

Update: kotlin:1.6.0 is compatible with hilt:2.40.5, thanks @Nazanin Nasab

Currently Kotlin 1.5.21 is compatible with Hilt 2.38.

dependencies {
    ...
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.21"
    classpath "com.google.dagger:hilt-android-gradle-plugin:2.38"
}

Thanks for the answer , i had to do a slight tweak in order to work for me because i'm using Arctic Fox, hopefully this answer will help as well

Build.gradle (project)

buildscript {
ext {
    compose_version = '1.0.0'
}
repositories {
    google()
    mavenCentral()
}
dependencies {
    classpath 'com.android.tools.build:gradle:7.1.0-alpha05'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.10"
    classpath "com.google.dagger:hilt-android-gradle-plugin:2.37"
}
}

Build.gradle (app)

//Dagger - Hilt
implementation "com.google.dagger:hilt-android:2.34-beta"
kapt "com.google.dagger:hilt-android-compiler:2.34-beta"
implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"
kapt "androidx.hilt:hilt-compiler:1.0.0"
implementation 'androidx.hilt:hilt-navigation-compose:1.0.0-alpha03'

Answer 3

Adding this line to build.gradle dependencies helped me:

kapt("org.jetbrains.kotlinx:kotlinx-metadata-jvm:0.3.0")

Answer 4

general solution - in AS build console click link at bottom - build with -stacktrace param and find which annotation processor (KAPT) is causing error - then try to update dependency - if you are lucky new version should be available and supporting your gradle version

message in build output you should lookin for

Try:
Run with --stacktrace option to get the stack trace. Run with --info or 
--debug option to get more log output. Run with --scan to get full insights.

Answer 5

I got same here. I was using dagger:hilt-android:2.33-beta with Kotlin 1.5.10.Please try this

Project gradle

implementation "com.google.dagger:hilt-android:2.33-beta"

Module gradle

plugins {
    ...
    id 'dagger.hilt.android.plugin'
}
dependencies {
    ...
    //dagger-hilt
    implementation "com.google.dagger:hilt-android:2.35.1"
    kapt "com.google.dagger:hilt-android-compiler:2.35.1"
}

Answer 6

If any solution solved your problem. Go to https://dagger.dev/hilt/gradle-setup, in Using Hilt with Kotlin section, copy the version mentioned in dependencies and update your build.gradle accordingly
