react-native: duplicate entry error related to okhttp3 when integrating React Native into existing Android project

Description

After adding React Native to an existing Android project, I get the following error when running ./gradlew assembleDebug:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':driver:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: okhttp3/internal/ws/RealWebSocket$1.class

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

This project already had a dependency on okhttp3, so I’m not sure how to make Gradle ignore the React Native dependency on it.

Additional Information

React Native version: 0.31
Platform: Android
Operating System: MacOS 10.11.6 (15G1217)

I resolved that forcing for all my dependencies would be the same. I had already some dependencies using v3.5.0 and having the conflict with new okhttp-ws integrated into v3.5.0 🤦‍♂️

It’s a workaround. Be aware that with this one we cannot use v3.5.0.

configurations.all { resolutionStrategy.force 'com.squareup.okhttp3:okhttp:3.4.1' }

No fix yet. I haven’t had time to investigate further. Like I said above, also not sure if this belongs here or on my Stack Overflow question above.

could you find a fix @lyahdav i’m having exact same issue, but when i use this code


configurations.all {
    // OkHttp 3.5.0+ includes the websockets API, so we need this to prevent a conflict
    exclude module: 'okhttp-ws'
}

i’m getting another! see this issue

thanks!
