Conflict Gson with Retrofit 2

[kainjinez]

I found you used Gson 2.5 for SkyWay. But it was conflict with Retrofit 2 compile 'com.squareup.retrofit2:converter-gson:2.1.0' This is my error log while compiling Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/gson/annotations/Expose.class How do I solve (or exclude) this?

@kainjinez A similar inquiry was in the past. Sorry for only Japanese. https://groups.google.com/forum/#!msg/skywayjs/FONoQgVLP04/NdWYtsOLDAAJ

Proposed 1

This error could be avoided by unpacking SkyWay.aar, deleting "libs / gson - 2.5.jar", and compressing it again.

Proposed 2

// build.gradle

configurations {
    all*.exclude module: 'gson'
}

Thanks. I tried same as your proposed 1 yesterday, and It looks good for now. Thanks

Hi kainjinez,

I have the same issue like you. Could you tell me how exactly did you compress the lib folder after deleting the gson jar file? I'm using Windows.

Thank you

@tuancoltech Please open aar file with WinRAR, then delete gson-2.5.jar in lbs folder. You don't need to extract it before delete, because WinRAR will extract and compress it automatically.

@kainjinez Thank you very much, it works like a charm.
