failed to resolve: com.google.firebase:firebase-core:16.0.0

thank for help this is the full gradle file

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "28.0.0"
    defaultConfig {
        applicationId "com.softya.demo"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:support-v4:25.3.1'
    testCompile 'junit:junit:4.12'
    compile 'com.google.firebase:firebase-core:16.0.0'
}
apply plugin: 'com.google.gms.google-services'

and this is the gradle file code

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
        classpath 'com.google.gms:google-services:4.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

Can you please show complete `build.gradle`? Maybe your forgot to put `jcenter()` and `google()` in your build script repositories. — Yosi Pramajaya, Jun 11 '18 at 01:07
Is it all your top-level `build.gradle`? Not the app level, but the project / top level `build.gradle` — Yosi Pramajaya, Jun 11 '18 at 01:24

I notice you need to updates a lot of your scripts.

For example, let's start with your top-level build.gradle. You should no longer use android gradle plugin 2.+, instead you should use version 3.1.x

And to do that, you should put google() in your repositories.

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

buildscript {
   repositories {
      jcenter()
      //Add this line
      google()
   }
   dependencies {
      //Please update it to 3.1.x
      classpath 'com.android.tools.build:gradle:3.1.2'
      //Update to the latest version as well
      classpath 'com.google.gms:google-services:4.0.1'
      // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
   }
}

Some tips:

Try to update your app-level build.gradle, from compile to implementation since they will be deprecated soon.

You have to add the google() Google's Maven repository for all projects

allprojects {
    repositories {
        jcenter()
        google()
    }
}

I solved this with this script in the build.gradle [Proyect]

buildscript {
    ext.kotlin_version = '1.2.30'
    repositories {
        google()
        jcenter()
        maven {
            url 'https://dl.bintray.com/android/android-tools'
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
    }
}
