I'm trying to use the new Navigation Architecture Component for android and I'm getting the error Failed to resolve: androidx.lifecycle:lifecycle-viewmodel-ktx:1.1.1 when I'm defining the lifecycle_version to "1.1.1"

I'm basically just copying and pasting what is in the documentation so I'm running out of ideas of what is wrong in here :(

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.mobile.codgin.newnavigation"
        minSdkVersion 21
        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 {
    def lifecycle_version = "1.1.1"

    // ViewModel and LiveData
    implementation "android.arch.lifecycle:extensions:$lifecycle_version"
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
    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'
}

try replace 

implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"

with this 

//https://mvnrepository.com/artifact/androidx.lifecycle/lifecycle-viewmodel-ktx
implementation group: 'androidx.lifecycle', name:'lifecycle-viewmodel-ktx', version: '2.0.0-alpha1'

then sync again.

You can have a look here : https://mvnrepository.com/artifact/androidx.lifecycle/lifecycle-viewmodel-ktx/2.0.0-alpha1

it seems to be that the repository was emptied somehow. Hence, you can not download it from the repository.

When it shows you this error add this code to section build.gradle

configurations {
    all {
        exclude group: 'androidx.lifecycle', module: 'lifecycle-viewmodel-ktx'
    }
}
