Question

App Building error:'app:checkDebugDuplicateClasses' 我知道删除一个类可以解决这个错误，但我不知道如何删除它或者有没有其他方法可以解决这个问题。

谢谢

FAILURE：构建失败，出现异常。什么地方出了错：任务“:app:checkDebugDuplicateClasses”执行失败。执行 com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable 时发生故障在模块中发现重复的类 com.google.firebase.iid.FirebaseInstanceIdReceiver jetified-firebase-iid-21.0.1-runtime (com.google.firebase:firebase-iid:21.0.1) 和 jetified-firebase-messaging-22.0.0-runtime (com.google.firebase:firebase-messaging:22.0.0) 转到文档以了解如何 d.android.com/r/tools/classpath-sync-errors 修复依赖解析错误

试试：使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。使用 --scan 运行以获得完整的见解。

Answer 1

您有 mavenCentral 和 jcenter 作为存储库。从您的项目 gradle 文件中删除 jcenter()，因为它已经过时了。

此外，删除您的 firebase-messaging 依赖项的版本：实现“com.google.firebase:firebase-messaging”
