I get the following warning when I want to use @AndroidEntryPoint which is a property of hilt in my project.

 Expected @AndroidEntryPoint to have a value. Did you forget to apply the Gradle Plugin? (dagger.hilt.android.plugin)

When I try to add id 'dagger.hilt.android.plugin' to the module level build.gradle file of my project, I get the following error.

org.gradle.api.plugins.UnknownPluginException: Plugin [id: 'dagger.hilt.android.plugin'] was not found in any of the following sources:

I tried to add it to the build.gradle file at the Module level of the project as follows. They all give an error.

I tried to add it as a classpath to the project level build.gradle file, in this case I still get an error.

When I created the default project, a settings.gradle structure was created as follows. This is my first time using this build. My version of Android Studio Android Studio - Bumblebee | 2021.1.1 Canary 13

For adding dagger hilt to your project. Follow these steps

Add hilt dependencies to your module's build.gradle. I assume you are using Kotlin, otherwise you have to use annotationProcessor insted of kapt plugin.

dependencies {
  //..
  implementation 'com.google.dagger:hilt-android:2.39.1'
  kapt 'com.google.dagger:hilt-compiler:2.39.1'
  //..
   }

Add hilt gradle plugin to project's build.gradle.

dependencies {
    //..
    classpath 'com.google.dagger:hilt-android-gradle-plugin:2.39.1'
  }

Apply kotlin-kapt and hilt plugins to module build.gradle

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

After a long struggle, I solved the problem as follows;

I added a resolutionStrategy to settings.gradle as below.

 pluginManagement {
        repositories {...}
        plugins { ...}
     resolutionStrategy {
            eachPlugin {
                if( requested.id.id == 'dagger.hilt.android.plugin') {
                    useModule("com.google.dagger:hilt-android-gradle-plugin:2.39.1")
                }
            }
        }
    }

Then, when I added the hilt plugin as below to the module level build.gradle file, it was updated correctly.

plugins{
...
id 'dagger.hilt.android.plugin'
}
