Aucune méthode statique métafactory

J'ai un problème avec mon application qui, lorsque je me connecte, se bloque et j'obtiens l'erreur:

java.lang.NoSuchMethodError: No static method metafactory(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite; in class Ljava/lang/invoke/LambdaMetafactory; or its super classes (declaration of 'java.lang.invoke.LambdaMetafactory' appears in /apex/com.android.runtime/javalib/core-oj.jar)

J'ai essayé de jouer avec les gradles et de changer les variables. Le problème semble provenir de ce paquet:

import retrofit2.Retrofit;
import retrofit2.converter.scalars.ScalarsConverterFactory;

public class RetrofitClient {
    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseURL)
    {
        if(retrofit == null)
        {
            retrofit = new Retrofit.Builder()
                    .baseUrl(baseURL)
                    .addConverterFactory(ScalarsConverterFactory.create())
                    .build();
        }
        return retrofit;

    }
    }

Il donne ensuite une autre référence à:

import com.example.usub.Remote.IGoogleAPI;
import com.example.usub.Remote.RetrofitClient;
public class Common {
    public static  final String baseURL = "https://maps.googleapis.com";
    public static IGoogleAPI getGoogleAPI()
    {
        return RetrofitClient.getClient(baseURL).create(IGoogleAPI.class);
    }
}

Voici mon gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "com.example.usub"
        minSdkVersion 26

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

Une idée sur la façon de trouver la méthode pour corriger l'erreur?

Essayez de basculer vers la compatibilité Java 8, pour une décompression correcte de certaines bibliothèques:

android {

    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = "1.8"
    }
}

En outre, Google JSON API pourrait plutôt avoir besoin de GsonConverterFactory.
