如何在构建期间修复此 Duplicate class 错误？

Question

我正在尝试在我的 android 应用程序中同时使用 jitsi 和 opentok，并相应地切换它们。

这些是我的 build.gradle(app) 依赖项

//使用的opentok依赖

implementation files('libs/opentok-android-sdk-2.15.2.aar')

//使用jitsi依赖

implementation ('org.jitsi.react:jitsi-meet-sdk:2.5.0')

我的构建失败，出现这样的错误

谢谢，帮我解决这个问题

Answer 1

这两个依赖项都使用 WebRTC 并使用它们导入 org.webrtc， 我可以建议的最好方法是使用 Opentalk 源代码文件（而不是 aar 依赖项，如果可用）并使用这些文件并使用 Jitsi 本身附带的 webrtc 依赖项。考虑到你不能使用 Jitsi 源代码作为它第一次编译时使用 react native 依赖项。

WebRTC 极大地增加了您的应用程序方面。反正你也不想导入两次。

Answer 2

在我的情况下，我通过删除一些库解决了问题：确保您使用了两个库（一个在您的 gradle 中的实现中，另一个是一个库，因此会产生重复错误）

1. 实施组：'org.webrtc'，名称：'google-webrtc'，版本：'1.0.19742'
2. 实现文件('libs/autobanh.jar')

在您的情况下，请确保删除两个库之一:((opentok-android-sdk-2.15.2.aar) 和 jetified-react-native-webrtc-1.75.2-jitsi-2994175-runtime.jar)

解决方案： 删除第二个并使缓存无效并重新启动并享受:)

Answer 3

您正在寻找管理传递依赖，解决冲突问题的通用方法是从带来它的依赖之一中排除 传递依赖：

dependencies {
  compile('com.example.m:m:1.0') {
     exclude group: 'org.unwanted', module: 'x 
  }
  compile 'com.example.l:1.0'
}

您可以在 Gradle 的 dependency management 阅读更多内容。
