我开始在我的项目中使用 MLKit 条形码扫描仪，并Duplicate class在尝试运行应用程序时收到错误消息。另外，我尝试了exclude firebase-commonand exclude firebase-components，但没有帮助，因为它破坏了推送通知或 MLKit 扫描器。

从 Firebase 和 Google 我们使用这些依赖项：

playServices: [
   base     : "com.google.android.gms:play-services-base:17.0.0",
   maps     : "com.google.android.gms:play-services-maps:17.0.0",
   location : "com.google.android.gms:play-services-location:17.0.0",
   safetynet: "com.google.android.gms:play-services-safetynet:17.0.0",
],
firebase: [
   messaging: "com.google.firebase:firebase-messaging:20.0.0",
   barcode: "com.google.mlkit:barcode-scanning:16.0.0"
]

请尝试将其更新到最新版本的 Firebase。第一季度底层基础设施发生了一些变化。
