我开始在项目中使用MLKit条形码扫描仪，并在尝试运行该应用程序时收到Duplicate class错误。
另外，我尝试使用exclude firebase-common和exclude firebase-components，但没有帮助，因为它破坏了推送通知或MLKit扫描程序。
在Firebase和Google中，我们使用以下依赖项:
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"
]

请尝试将其更新为最新版本的Firebase。第一季度的基础架构发生了一些变化。
