我正在使用android studio创建一个android应用程序。我想使用以下依赖项“
com.google.gson：gson：2.8.5”。我将其添加到我的应用程序的build.gradle中，但是遇到以下错误：无法解决：com.google.gson：gson：2.8.5

我尝试了以下操作：-降级依赖项的版本-降级buildToolsVersion的版本-安装SDK中可用的所有Google软件包-
将mavenCentral（）添加到我的build.gradle项目中

我的build.gradle应用程序：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.0"
    defaultConfig {
        applicationId "com.example.topquiz"
        minSdkVersion 15
        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:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.android.material:material:1.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'org.jetbrains:annotations-java5:15.0'
    implementation 'com.google.gson:gson:2.8.5' //Store object into SharedPreferences
}

我的build.gradle项目：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

非常感谢您的帮助
