编译我的项目时，出现以下错误消息：
Program type already present: com.google.android.gms.internal.measurement.zzabn Message{kind=ERROR, text=Program type already present: com.google.android.gms.internal.measurement.zzabn, sources=[Unknown source file], tool name=Optional.of(D8)}
要么
D8: Program type already present: com.google.android.gms.internal.measurement.zzabo
在Gradle Log中使用以下stacktrace

Firebase对SDK进行了更新：
Firebase Android SDK现在具有独立的版本号，可以进行更频繁，更灵活的更新。
更新所有Firebase依赖项以使用最新版本：
Firebase Core com.google.firebase:firebase-core:15.0.2 Ads com.google.firebase:firebase-ads:15.0.0 Analytics com.google.firebase:firebase-analytics:15.0.2 App Indexing com.google.firebase:firebase-appindexing:15.0.0 Authentication com.google.firebase:firebase-auth:15.1.0 Cloud Firestore com.google.firebase:firebase-firestore:16.0.0 Cloud Functions com.google.firebase:firebase-functions:15.0.0 Cloud Messaging com.google.firebase:firebase-messaging:15.0.2 Cloud Storage com.google.firebase:firebase-storage:15.0.2 Crash Reporting com.google.firebase:firebase-crash:15.0.2 Crashlytics com.crashlytics.sdk.android:crashlytics:2.9.1 Invites com.google.firebase:firebase-invites:15.0.1 Performance Monitoring com.google.firebase:firebase-perf:15.1.0 Realtime Database com.google.firebase:firebase-database:15.0.0 Remote Config com.google.firebase:firebase-config:15.0.2

请同时更新google-services插件：
google-services
classpath 'com.google.gms:google-services:3.3.1'
你可以在这里找到最新的Google服务
另外，请检查此链接以了解更改，并按照文章中列出的步骤进行操作：
宣布新的SDK版本控制
截至今天，该google-services插件的最新版本是4.3.3。所以，你的依赖看起来像
classpath ‘com.google.gms:google-services:4.3.3’
