android - 如何使用 Retrofit2 解决 NoSuchMethodError？

问题描述

我测试了一些示例代码，但 Retrofit Builder 发生错误。我可以检查初始化中的错误。

我读了两篇文章，但没有我的案例。
Retrofit2 NoSuchMethodError 与使用 OkHttp3 的外部 AAR 3.3.1
单元测试：模拟改造获取请求时的 NoSuchMethodError

查看其他文章，在某些方法中也会出现同样的错误。
但就我而言，它发生在初始化中。

创建一个新项目，只是添加改造会导致同样的问题。

我的构建等级：

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'
}

我的错误代码：

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();
    }
}

和错误消息：
