Could not resolve com.android.tools.build:gradle:3.3.2

问题

I was trying to add firebase auth to my android project but getting this error. I have tried adding 'com.google.firebase:firebase-core:16.0.3' too but its taking more than 40 mins and still not syncing the gradle.

This is build.gradle file:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "myaid.startup"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.google.firebase:firebase-auth:16.0.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

This is app.gradle file:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath 'com.google.gms:google-services:4.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

This is the error:

FAILURE: Build failed with an exception.

What went wrong: A problem occurred configuring root project 'MyAid'.

I have resolved this problem by removing all my .gradle files, SDK files, .m2 files, .androidstudio files and then re-installing it.

Please check your gradle's proxy settings. Enable it or disable it in the following file:

~/.gradle/gradle.properties

Like:

systemProp.https.proxyPort=1080
systemProp.http.proxyHost=127.0.0.1
systemProp.https.proxyHost=127.0.0.1
systemProp.http.proxyPort=1080

Advices:

If your connection to repositories is not stable, use a proxy instead of direct connection.
If you used to use a proxy for gradle, check if it is still working.
