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'

}
}

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.

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 :

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.

beginner Gradle error "dependency's AAR metadata"

this my Gradle
plugins {

}
android {

defaultConfig {
applicationId "com.example.tablayout"

testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
testImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}
this output:
The minCompileSdk (31) specified in a dependency's AAR metadata
(META-INF/com/android/build/gradle/aar-metadata.properties) is greater
than this module's compileSdkVersion (android-26). Dependency:
androidx.appcompat:appcompat:1.4.2.

compileSdkVersion and targetSdkVersion You have to get it to level 31
Version 28 (intended for Android Pie and below) is the last version of the legacy support library, so we recommend that you migrate to AndroidX libraries when using Android Q and moving forward.
Old:
implementation 'com.android.support:design:26.0.0'
New:
implementation 'com.google.android.material:material:1.6.1'
You can update the file like this:
android {
compileSdkVersion 31
defaultConfig {
applicationId "com.example.tablayout"
minSdkVersion 19
targetSdkVersion 31
versionCode 1
versionName "1.0"
testInstrumentationRunner defaultTestInstrumentationRunner
}
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:1.4.2'
implementation 'com.google.android.material:material:1.6.1'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
testImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

Import the android support library

I'm completely new to android and I'm trying some stuff. But there is a problem that I can't resolve. I'm trying to import some android support library and even if it seems like I did it properly by adding google() to my Gradle build, and by clicking Sync Now there is an error. I even used the project structure manager to add the dependencies and it still appears red.
Here is my build.gradle module file :
plugins {
id 'com.android.application'
}
allprojects {
repositories {
google()
}
}
android {
compileSdkVersion 30
buildToolsVersion "30.0.3"
defaultConfig {
applicationId "com.avoidspleen.exossupspe"
minSdkVersion 21
targetSdkVersion 30
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:1.2.0'
implementation 'com.google.android.material:material:1.3.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
// Appears red from now
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
// End of red
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}
I'm using JetBrains toolbox to update Android Studio version 4.1.2.

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.
