React Native :app:checkDebugDuplicateClasses 失败

Question

我正在尝试通过直接采用来自this gist 的代码来为 React Native 项目中的 websocket 连接实现Trustmanager。它需要okhttp-ws 模块才能运行。

但是，它在:app:checkDebugDuplicateClasses 失败

Execution failed for task ':app:checkDebugDuplicateClasses'.

  java.lang.RuntimeException: java.lang.RuntimeException:

所以，我从app/build.gradle 中排除了okhttp

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    
    implementation "com.facebook.react:react-native:+"  // From node_modules

    implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.0.0"

    // compile the ws module
    implementation('com.squareup.okhttp3:okhttp-ws:+'){
        // exclude the conflicting module
        exclude group:'com.squareup.okhttp3', module:'okhttp'
    }

    debugImplementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}") {
        exclude group:'com.facebook.fbjni'
    }

    debugImplementation("com.facebook.flipper:flipper-network-plugin:${FLIPPER_VERSION}") {
        exclude group:'com.facebook.flipper'
        // interestingly, it's been excluded here too
        exclude group:'com.squareup.okhttp3', module:'okhttp'
    }

    debugImplementation("com.facebook.flipper:flipper-fresco-plugin:${FLIPPER_VERSION}") {
        exclude group:'com.facebook.flipper'
    }

    if (enableHermes) {
        def hermesPath = "../../node_modules/hermes-engine/android/";
        debugImplementation files(hermesPath + "hermes-debug.aar")
        releaseImplementation files(hermesPath + "hermes-release.aar")
    } else {
        implementation jscFlavor
    }
}

仍然，我得到了同样的错误。因此，我访问了错误显示的开发人员文档link，并尝试在 Android Studio 中搜索 Class okhttp3.internal.ws.RealWebSocket。但它只显示缓存文件夹中包含麻烦类的一些文件，包括okhttp 和ws 模块，我无法删除这些文件。对于其他类，它只显示来自okhttp 模块的文件，我也无法删除这些文件。有解决方法吗？我错过了什么？

Answer 1

WebSocket 现在是核心库的一部分。 https://square.github.io/okhttp/4.x/okhttp/okhttp3/-web-socket/

所以你应该升级到 4.9.0 并停止依赖 okhttp-ws，或者恢复到 3.12.12（这是受支持的旧分支）。

这里有一个示例，说明如何在 OkHttp https://github.com/square/okhttp/blob/master/samples/slack/src/main/java/okhttp3/slack/SlackApi.java 中使用 WebSocket 支持

或者使用内置的 react-native 支持 https://reactnative.dev/docs/network
