Not able to import @Inject annotation

Question

I have implemented Hilt dependencies in my project, but when I need the @Inject annotation for my constructor, it's not working. basically when I tried to import it manually i found out, the inject folder inside javax is empty. So the structure is like javax.inject. And after that I get nothing as the inject folder is empty. I have tried rebuilding and cleaning he project. I also tried by Invalidating caches but nothing seems to work. How can I make this work ?

Dependencies List

dependencies {
    implementation(project(":shared"))

    implementation(AndroidX.appCompat)

    implementation(Compose.runtime)
    implementation(Compose.runtimeLiveData)
    implementation(Compose.ui)
    implementation(Compose.material)
    implementation(Compose.uiTooling)
    implementation(Compose.foundation)
    implementation(Compose.compiler)
    implementation(Compose.constraintLayout)
    implementation(Compose.activity)
    implementation(Compose.navigation)

    implementation(Google.material)

    implementation(Hilt.hiltAndroid)
    implementation(Hilt.hiltNavigation)
    kapt(Hilt.hiltCompiler)

    implementation(Kotlinx.datetime)

    debugImplementation(SquareUp.leakCanary)
}

Hilt version - 2.37

All your dependency is right, it's just an android studio bug!

I am having the same problem using Android Studio 4.2.2, I solved using the beta version of Android Studio

Still having this issue on Android Studio Arctic Fox | 2020.3.1 Patch 3 downloaded Android studio Bumblebee and it worked – barryalan2633 Oct 20 '21 at 18:27
I'm not entirely sure what happened with my Android Studio installation, but the only way I could fix this was with Jetbrains toolbox to uninstall and reinstall arctic fox and managed to fix the issue for me. – Andrew Steinmetz Jan 07 '22 at 05:47
Solved uninstall Artic Fox version, and download Bumblebee version – Manuel Lucas Mar 26 '22 at 17:31

I believe you are missing the plugins in the gradle file

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

If your javax folder is empty, you need to remove the javax cache and let the Gradle download it again.

right-click on javax library and choose Library Properties
in the dialog, go to the address and remove that folder to let the Gradle download the library again.
sync the Gradle. It will download the jar and the folder will not be empty anymore

Make sure you're annotating with the @Inject (uppercase I) and not @inject with a lowercase i.
