Cannot sync gradle with Persistance Room dependencies

Question

I wanted to change from SQLite to Room. But when I start a new project and implement the dependencies from https://developer.android.com/topic/libraries/architecture/adding-components#room I'm getting a sync failure. And I don't know why. I also inserted maven in repositories...

build.gradle(Project)

// 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:3.1.4'


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

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

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

build.gradle(Module)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.beuttlerj.saveyourreceipt"
        minSdkVersion 23

        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    // optional - Guava support for Room, including Optional and ListenableFuture
    implementation "android.arch.persistence.room:guava:$room_version"

    // Test helpers
    testImplementation "android.arch.persistence.room:testing:$room_version"
}

Either you have a slow internet connection or the room version is not working with you, this could happen frequently, try the version 1.0.1 and see.
