open SDK manager and install repository of version 27 then it will work either you can check which API level install properly you can change into the gradle like this :

android {
    compileSdkVersion 27
    defaultConfig {
        minSdkVersion 18
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}


dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:27.0.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:0.5'
    implementation 'com.google.android.gms:play-services:11.8.0'
    implementation 'com.google.android.gms:play-services-maps:11.8.0'
    implementation 'com.android.support:design:27.0.1'
}

to this if you have API level 26 :=

android {
    compileSdkVersion 26
    defaultConfig {
        minSdkVersion 18
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}


dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:26.0.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:0.5'
    implementation 'com.google.android.gms:play-services:11.8.0'
    implementation 'com.google.android.gms:play-services-maps:11.8.0'
    implementation 'com.android.support:design:26.0.1'
}

you can change like this then your problem will solved.

By the way - `'com.google.android.gms:play-services:11.8.0'` is compiling much more than just maps — OneCricketeer, Feb 06 '18 at 08:49

Just click on "install repository and sync project" in your error. It will install the required repository and solve your problem.

Thanks to all my colleagues. Button "Install repository and synchronize project" does not work. 27 version is already installed.

I changed the 27 version to 25 and the error disappeared.
