title: Firebase not working Android Studio 3.0.1 [com.android.support:support-core-utils:27.1.0]
body: <p>I'm trying to sync with Firebase with my project I use the tool from Android Studio --> Firebase and then I do the steps (This is new Project) <a href="https://ibb.co/farpSn" rel="nofollow noreferrer">Image</a>.
  Android Studio version <strong>3.0.1</strong></p>
  
  <p>The build.gradle in App folder is:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 26
      defaultConfig {
          applicationId "com.example.eranp.fiberbase"
          minSdkVersion 19
          targetSdkVersion 26
          versionCode 1
          versionName "1.0"
          testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
      }
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      implementation fileTree(dir: 'libs', include: ['*.jar'])
      implementation 'com.android.support.constraint:constraint-layout:1.0.2'
      implementation 'com.google.firebase:firebase-database:11.0.4'
      testImplementation 'junit:junit:4.12'
      androidTestImplementation 'com.android.support.test:runner:1.0.1'
      androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
  }
  
  
  apply plugin: 'com.google.gms.google-services'
  </code></pre>
  
  <p>The build.gradle in Project folder</p>
  
  <pre><code>// Top-level build file where you can add configuration options common to all sub-projects/modules.
  
  buildscript {
  
      repositories {
          jcenter()
          maven {
              url "https://maven.google.com"
          }
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:3.0.1'
          compile "com.android.support:support-core-utils:27.1.0"
  
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
          classpath 'com.google.gms:google-services:3.1.0'
      }
  }
  
  allprojects {
      repositories {
          google()
          jcenter()
      }
  }
  
  task clean(type: Delete) {
      delete rootProject.buildDir
  }
  </code></pre>
  
  <p>But when I sync the project I have this Error:</p>
  
  <blockquote>
    <p>Error:(13, 0) Could not find method compile() for arguments
    [com.android.support:support-core-utils:27.1.0] on object of type
    org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.</p>
    
    <p>Please install the Android Support Repository from the Android SDK
    Manager.</p>
  </blockquote>
  
  <p>But this is installed: <a href="http://ibb.co/gG0G7n" rel="nofollow noreferrer">Image</a>. </p>
  
  <p>I tried for a week to work with Firebase but anything working to sync.
  How can I fix this?
  thank you for helping!</p>
