failed linking references after update of gradle Android Studio

Question

I got this error after update my Gradle (I have also added maven{jitpack.io} and geofirestore dependencies at the same of updating Gradle) :

Android resource linking failed Output:  C:\Users\Paul\AndroidStudioProjects\How2Ride2\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-v28\values-v28.xml:7: error: resource android:attr/dialogCornerRadius not found.

How can I solve this?

Here my Project build gradle:

buildscript {      repositories {         google()         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:3.2.0'           // NOTE: Do not place your application dependencies here; they belong         // in the individual module build.gradle files         classpath 'com.google.gms:google-services:4.0.2'     } }  allprojects {     repositories {         google()         jcenter()          maven { url 'https://jitpack.io' }     } }  task clean(type: Delete) {     delete rootProject.buildDir } 

and my Module build gradle:

    apply plugin: 'com.android.application'  android {     compileSdkVersion 27     defaultConfig {         applicationId "com.how2ride.how2ride"         minSdkVersion 21         targetSdkVersion 27         versionCode 1         versionName "1.0"         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"         resConfigs "en", "fr"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     implementation fileTree(dir: 'libs', include: ['*.jar'])     //noinspection GradleCompatible     implementation 'com.android.support:appcompat-v7:27.1.1'     implementation 'com.android.support:support-v4:27.1.1'     implementation 'com.android.support:design:27.1.1'     implementation 'com.google.android.gms:play-services-maps:15.0.1'     implementation "com.google.android.gms:play-services-location:15.0.1"     implementation 'com.google.firebase:firebase-ads:15.0.1'     implementation 'com.google.firebase:firebase-core:16.0.3'     implementation 'com.firebaseui:firebase-ui-auth:4.1.0'     implementation 'com.google.firebase:firebase-auth:16.0.3'     implementation 'com.google.firebase:firebase-firestore:17.1.0'     implementation 'com.github.imperiumlabs:GeoFirestore-Android:v1.1.1'     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' }  apply plugin: 'com.google.gms.google-services' 

I have the last version of android studio and my project worked perfectly before upgrading my gradle...
