Android：在 jetified-play-services-measurement 和 jetified-play-services-measurement-impl 模块中发现重复的类

Question

我正在尝试更新我的 Android 项目之一的依赖项，但收到了这个奇怪的错误。

罪魁祸首是 AdMob 的这一行（我之前使用的是 20.6.0）：

implementation "com.google.android.gms:play-services-ads:21.0.0"

我收到一堆错误：

在模块 jetified-play-services-measurement-base-20.1.2-runtime 中发现重复的类 com.google.android.gms.internal.measurement.zzhx (com.google.android.gms:play-services-measurement-base: 20.1.2) 和 jetified-play-services-measurement-impl-20.1.1-runtime (com.google.android.gms:play-services-measurement-impl:20.1.1)

在模块 jetified-play-services-measurement-base-20.1.2-runtime 中发现重复的类 com.google.android.gms.internal.measurement.zzna (com.google.android.gms:play-services-measurement-base: 20.1.2) 和 jetified-play-services-measurement-impl-20.1.1-runtime (com.google.android.gms:play-services-measurement-impl:20.1.1)

在模块 jetified-play-services-measurement-base-20.1.2-runtime 中发现重复的类 com.google.android.gms.internal.measurement.zznb (com.google.android.gms:play-services-measurement-base: 20.1.2) 和 jetified-play-services-measurement-impl-20.1.1-runtime (com.google.android.gms:play-services-measurement-impl:20.1.1)

在模块 jetified-play-services-measurement-base-20.1.2-runtime 中发现重复的类 com.google.android.gms.internal.measurement.zznc (com.google.android.gms:play-services-measurement-base: 20.1.2) 和 jetified-play-services-measurement-impl-20.1.1-runtime (com.google.android.gms:play-services-measurement-impl:20.1.1)

...

以下是我在项目中使用的所有依赖项build.gradle (:app)：

dependencies {
    implementation "androidx.recyclerview:recyclerview:1.2.1"
    implementation 'androidx.core:core-ktx:1.8.0'
    implementation 'androidx.appcompat:appcompat:1.4.2'
    implementation 'com.google.android.material:material:1.6.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    // Firebase & Crashlytics
    implementation platform('com.google.firebase:firebase-bom:29.2.1')
    implementation 'com.google.firebase:firebase-analytics-ktx'
    implementation 'com.google.firebase:firebase-crashlytics-ktx'
    //Navigation
    implementation "androidx.navigation:navigation-fragment-ktx:2.4.2"
    implementation "androidx.navigation:navigation-ui-ktx:2.4.2"
    // AdMob
    implementation "com.google.android.gms:play-services-ads:21.0.0"
    // Style
    implementation 'com.intuit.sdp:sdp-android:1.0.5'
    // Play Core
    implementation 'com.google.android.play:core:1.10.3'
    implementation 'com.google.android.play:core-ktx:1.8.1'
    // Billing
    implementation "com.android.billingclient:billing-ktx:5.0.0"
}

以及以下依赖项build.gradle (My App)：

buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.1.3"
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.4.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.21"
        classpath "com.google.gms:google-services:4.3.10"
        classpath "com.google.firebase:firebase-crashlytics-gradle:2.8.1"
    }
}

是什么导致了这个错误？如果我恢复play-services-ads到 20.6.0，我不会收到任何错误。

感谢您的帮助

Answer 1

你还需要更新 implementation platform('com.google.firebase:firebase-bom:29.2.1'),到

 implementation platform('com.google.firebase:firebase-bom:30.1.0')

Answer 2

如错误消息中所述，您需要解决/删除一些重复的类（很可能也具有不兼容的版本设置）。对于我的情况，我需要升级我的 Firebase Analytics。这就是我追踪问题的方法：

我跑了

./gradlew -q app:dependencies

|    |    \--- com.google.android.gms:play-services-measurement-sdk:18.0.3

显然，问题出在我的项目的这两个直接依赖项中com.google.android.gms:play-services-ads:21.2.0，并且com.google.firebase:firebase-analytics:18.0.3都指定了不同的版本play-services-measurement

如果我们进一步查看 pom 文件play-services-measurement:18.0.3：

    <dependency>
      <groupId>com.google.android.gms</groupId>
      <artifactId>play-services-measurement-base</artifactId>
      <version>[18.0.3]</version>
      <scope>compile</scope>
      <type>aar</type>
    </dependency>
    <dependency>
      <groupId>com.google.android.gms</groupId>
      <artifactId>play-services-measurement-impl</artifactId>
      <version>[18.0.3]</version>
      <scope>compile</scope>
      <type>aar</type>
    </dependency>

它严格要求18.0.3 base，impl这使得Gradle无法自行解决该问题。

我选择将Firebase Analytics升级到20.1.2，问题已解决。
