在模块中发现重复的类 com.google.android.gms.internal.vision.zze

Question

我正在尝试使用 openCV 和 Firebase ML Kit 构建一个应用程序。但是在构建项目时出现以下错误：

Duplicate class com.google.android.gms.internal.vision.zze found in modules jetified-play-services-vision-20.0.0-runtime.jar (com.google.android.gms:play-services-vision:20.0.0) and jetified-play-services-vision-common-19.1.0-runtime.jar (com.google.android.gms:play-services-vision-common:19.1.0)

Go to the documentation to learn how to Fix dependency resolution errors.

我试过搜索完全相同的错误并没有得到任何结果，然后我搜索了重复的类问题，没有解决问题的某种方法，每个人都分享了他们的经验，但他们都没有为我工作。

这是我的build.gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "com.example.cameraactivity"
        minSdkVersion 21
        targetSdkVersion 30
        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 "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.3.1'
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.1'

    implementation 'com.google.firebase:firebase-ml-vision:24.1.0'
    implementation project(path: ':sdk')

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

}

都是关于这条线的：

implementation 'com.google.firebase:firebase-ml-vision:24.1.0'

当我评论这一行时，它在我构建项目时不会出错（我还没有添加功能）。提前致谢

Answer 1

在 build.gradle:Module 添加以下内容

implementation 'com.google.android.gms:play-services-vision:20.0.0'

implementation 'com.google.firebase:firebase-ml-vision:24.0.3'
implementation 'com.google.firebase:firebase-ml-vision-barcode-model:16.1.1'

在 build.gradle:Project

classpath 'com.google.gms:google-services:4.3.3'

在构建脚本--> 依赖项中。

Answer 2

我在使用 24.1.0 版本的 firebase-ml-vision 时遇到了同样的问题。以下是官方的解决方案：

Firebase 发行说明 MLKIT 自助修复

因此，我必须添加对 play-services-vision 的依赖项，而我之前不再需要它：

实施“com.google.android.gms：play-services-vision：20.1.1”

我希望他们会在下一个版本中修复它
