How can I solve NoSuchMethodError using Retrofit2?

Question

I tested some example code but Retrofit Builder occured error. I can check for errors in initialization.

I read two articles but no my case.
Retrofit2 NoSuchMethodError with external AAR that uses OkHttp3 3.3.1
Unit testing: NoSuchMethodError at mock retrofit get request

Looking at other articles, the same error occurs in certain methods.
But in my case it happens in initialization.

Creating a new project, just adding retrofits causes the same problem.

my build gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"
    viewBinding.enabled = true

    defaultConfig {
        applicationId "kr.ac.sunmoon.gijoe.camaps"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

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

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'com.google.android.gms:play-services-maps:17.0.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.android.material:material:1.1.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    // Mistake, missing lines, Start
    implementation 'com.squareup.retrofit2:retrofit:2.9.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
    // missing lines, End
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

my error code:

public class .... {
    private Retrofit mRetrofit;

    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        setRetrofitinit();
    }

    private void setRetrofitInit() {
        mRetrofit = new Retrofit.Builder()
            .baseUrl(getString(R.string.baseUrl))  <== Error: noSuchMethodError
            .addConverterFactory(GsonConverterFactory.create())
            .build();
    }
}

and Error Messages:

Have you added both the dependencies?`//Retrofit & OkHttp compile 'com.squareup.retrofit2:retrofit:2.5.0' // JSON Converter compile 'com.squareup.retrofit2:converter-gson:2.5.0'` — Sairaj Sawant, Jun 09 '20 at 12:59
@SairajSawant Oh, My Mistake. but after add two line, same error. I used it //implementation 'com.squareup.retrofit2:retrofit:2.9.0' //implementation 'com.squareup.retrofit2:converter-gson:2.9.0' — BlueMS, Jun 10 '20 at 01:56
@SairajSawant Yes, ```getString``` is not null. And when I typed directly URL, same error too. I don't know why this error is occurred. — BlueMS, Jun 10 '20 at 04:41

As mentioned here :

android {

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

    kotlinOptions {
        jvmTarget = "1.8"
    }
}
