Question

im getting this gradle sync error - The Hilt Android Gradle plugin is applied but no com.google.dagger:hilt-android dependency was found. can someone help please ? :)

im using kotlin dsl, i have libs.kt in buildSrc

buildSrc - build.gradle.kts:

plugins {
    `kotlin-dsl`
}

repositories {
    jcenter()
}

libs.kt in buildSrc

object libs {
        object hilt {
            private const val dagger_hilt_version = "2.30.1-alpha"
            private const val jetpack_hilt_version = "1.0.0-alpha02"

            const val gradlePlugin = "com.google.dagger:hilt-android-gradle-plugin:$dagger_hilt_version"
            const val android = "com.google.dagger:hilt-android:$dagger_hilt_version"
            const val android_compiler = "com.google.dagger:hilt-android-compiler:$dagger_hilt_version"

            const val jetpack_viewmodel = "androidx.hilt:hilt-lifecycle-viewmodel:$jetpack_hilt_version"
            const val jetpack_compiler = "androidx.hilt:hilt-compiler:$jetpack_hilt_version"
        }

        /* more objects + more constants */

    }

remove id("dagger.hilt.android.plugin")

sync gradle

add id("dagger.hilt.android.plugin")
