问题

我已经为这个问题纠结了几个小时，当我添加这个特定的依赖时，我目前遇到了一个重复类的错误。

implementation 'com.google.apis:google-api-services-vision:v1-rev369-1.23.0'

我的 App 级 Build.gradle 文件如下：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"
    defaultConfig {

        targetSdkVersion 30
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        vectorDrawables.useSupportLibrary = true

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    implementation 'androidx.annotation:annotation:1.1.0'
}
repositories {
    mavenCentral()
}

我的项目级 Build.gradle 文件如下：

// 顶层 Build 文件，在这里您可以添加所有子项目/模块都通用的配置选项。

buildscript {
    ext.kotlin_version = '1.4.10'
    repositories {
        google()
        jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        classpath 'com.google.gms:google-services:4.3.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // 注意：不要在此处放置应用程序的依赖项；它们应属于各个模块的 build.gradle 文件中
    }
}

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

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

```plaintext
将以下内容替换为：

    implementation 'com.google.apis:google-api-services-vision:v1-rev369-1.23.0'

用以下内容替换：

    implementation ('com.google.apis:google-api-services-vision:v1-rev369-1.23.0'){
        exclude group:'com.google.guava'
    }

英文:

Replace this

implementation &#39;com.google.apis:google-api-services-vision:v1-rev369-1.23.0&#39;

With this

implementation (&#39;com.google.apis:google-api-services-vision:v1-rev369-1.23.0&#39;){
exclude group:&#39;com.google.guava&#39;
}
