Failed to resolve com.android.support.test:runner:1.0.0 and 'com.android.support.test.espresso:espresso-core:3.0.0'

Question

This is my build.gradle(app)

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}


android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.my.app"
        minSdkVersion 16
        targetSdkVersion 26

    }
    
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
    }
}

    compile('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') {
        transitive = true;
    }
}

I have noted the controversial dependencies from here And I get the following errors

Failed to resolve:com.android.support.test.espresso:espresso-core:3.0.0

Failed to resolve:com.android.support.test:runner:1.0.0

I have updated the sdk manager, but still facing this. Do I have to downgrade to a lower version? Can anyone help?

Answer 1

I had the same problem when I wanted to try Espresso.

I've resolved it by adding

        maven {
            url "https://maven.google.com"
        }

to

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

in the project's build.gradle file. See https://developer.android.com/topic/libraries/testing-support-library/packages.html#gradle-dependencies.
