Error "error: package com.google.firebase.messaging does not exist" even though dependency is added

I have the following line in my MainActivity.java that is giving the error...
import com.google.firebase.messaging.FirebaseMessaging;
Which gives error:
error: package com.google.firebase.messaging does not exist
My app level build.gradle has the dependency added...
plugins {
id 'com.android.application'
id 'com.google.gms.google-services'
}
android {

}

}
}

targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation 'androidx.appcompat:appcompat:1.5.1'
implementation 'com.google.android.material:material:1.7.0'
implementation platform('com.google.firebase:firebase-bom:31.1.0')

testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.4'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.0'
}
The build process does not complain about any issue with the build.gradle, so I assume it is configured correctly (according to the firebase docs). I am not sure what else I can do to diagnose this issue, since there is no indication that the build file is misconfigured.

Glide error adding glide's dependency to project : could not resolve all files for configuration 'app:debugRuntimeClasspath'

I want to use Glide library in my project but after adding glide's dependencies i got this error when i run the app and gradle offline mode is off :

and this is my app build.geadle :
plugins {

}

implementation 'com.github.bumptech.glide:glide:4.14.2'
kapt 'com.github.bumptech.glide:compiler:4.14.2'
}
when i remove the glide's dependencies it work properly.

The problem was my vpn and Gradle could not download dependencies.
if it occur to you check that you connection is available or not.

How can I fix "Could not GET jcenter.bintray.com/com/google/dagger/dagger-android-processor/2.35.1/dagger-android-processor-2.35.1.pom"?

I'm practicing Dagger 2 from this tutorial:
vogella.com Dagger tutorial.
But I got this error while running my Android project:
Could not GET 'https://jcenter.bintray.com/com/google/dagger/dagger-android-processor/2.35.1/dagger-android-processor-2.35.1.pom'
How can I fix this issue?
This is my build.gradle Module:
plugins {
id 'com.android.application'
}
android {
compileSdkVersion 31
buildToolsVersion "31.0.0"
defaultConfig {
applicationId "com.vogella.android.dagger2simple"
minSdkVersion 17
targetSdkVersion 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'com.google.android.material:material:1.4.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.2'

annotationProcessor 'com.google.dagger:dagger-compiler:2.35.1'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}
android {
configurations.all {
resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
}
}

Replace jcenter() with mavenCentral() in all your build.gradle files.
As mentioned in migrating away from JCenter guide

building AAR in Android Studio

It's my first time building AAR
The official site says that All I hate to do is build APK and AAR will be assembled
Here's the quote:
But when I choose "Build Apk(s)" nothing happens.
Another tutorial says I have to choose Gradle-> library name -> tasks-> build-> :assembleRelease.
But there is no such thing :
How can I assemble library as AAR?
here's my gradle :
plugins {
id 'com.android.library'
id 'kotlin-android'
id 'kotlin-kapt'
}
android {
compileSdkVersion 29
buildToolsVersion "29.0.3"
defaultConfig {
minSdkVersion 17
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.3.2'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.2.1'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
def room_version = "2.2.3"
implementation "androidx.room:room-runtime:$room_version"
kapt "androidx.room:room-compiler:$room_version"
implementation "androidx.room:room-ktx:$room_version"
implementation "androidx.room:room-rxjava2:$room_version"
implementation 'com.google.code.gson:gson:2.8.2'
}

Just click assemble or add buildTypes.debug. While you don't have buildTypes.debug defined, it won't generate the tasks you are looking for (as there only is one configuration present there and so there is nothing to tell apart).

I did clean and rebuild the project it didn't help. Any help would be great
Thank you

I couldn't to reproduce topic issue. And due to newbie reputation score ­— comment-section read only for my account now. So I post the answer. Avoid blaming me if it possible, please.
Try to add to application build.gradle file following:
composeOptions {
kotlinCompilerVersion "1.3.70-dev-withExperimentalGoogleExtensions-20200424"
kotlinCompilerExtensionVersion "0.1.0-dev09"
}
just before buildTypes { … } block.
