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

Solution 1

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

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'

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

This is the Right way of resolving the error on latest SDK

[Nazanin Nasab]

Also these versions work for me: kotlin:1.6.0 , hilt:2.40.5

[Doilio Matsinhe]

This worked for me, I used the answer provided by @NazaninNasab since it has more up to date versions. cheers

[MD. Shafiul Alam Biplob]

That's the correct answer. It's for dependency/library version error and debug option shows the actual reason.

I would add: Visit the Gradle Build Setup page and verify EVERYTHING is up to date in your build.gradle files. Android Studio with it's suggestions helped me update only a part, but the Hilt Gradle Plugin was not, so I ended up having new and old version numbers that were causing the error.
