Amazon Cognito Auth library causes gradle IOException (Duplicate zip entry)

Question

Ever since I updated CognitoAuth to v2.6.13 I have had compile issues with gradle. This ONLY happens with release builds.

cognito library

'com.amazonaws:aws-android-sdk-cognitoauth:2.6.13'

The error I receive is the following:

Warning:Exception while processing task java.io.IOException: Can't write [C:\JAVASDK\AndroidStudio\AS_Workspace\example.android\app\build\intermediates\transforms\proguard\tech\release\0.jar] (Can't read [C:\Users\jeff.gradle\caches\transforms-1\files-1.1\aws-android-sdk-cognitoauth-2.6.13.aar\cc705c348189e750e6a133ffd448563c\jars\classes.jar(;;;;;;**.class)] (Duplicate zip entry [classes.jar:com/amazonaws/cognito/clientcontext/datacollection/BuildDataCollector.class]))

From research, it seems I need to exclude something but I do not know what. What am I missing? And is this more of a proguard issue, since this only fails with release builds?

EDIT

apply plugin: 'com.android.library'

// top-level build file to help synchronize library versions
ext {
    supportLib = "25.3.1"
    googleLib = "11.6.0"

Can you post a snippet of the dependencies section of your build.gradle file? Do you have both `aws-android-sdk-cognitoauth` and `aws-android-sdk-cognitoidentityprovider` in your dependencies? — Karthikeyan, Jan 15 '18 at 17:04
Thanks for posting the build.gradle. We are aware of this issue now and I am able to reproduce it when I include both cognitoauth and cognitoidentityprovider with latest version. We are looking into it and we will be fixing this issue as soon as possible. We will update you here when the issue is fixed and then you could include both the libraries with the latest version without any issue. Thank you for the patience and sorry for the inconvenience caused. — Karthikeyan, Jan 16 '18 at 20:01
We have fixed this issue in v2.6.14. Can you try upgrading both the SDKs to 2.6.14? — Karthikeyan, Jan 19 '18 at 01:46

Use the below command in Android studio terminal to get the dependency conflict data - [Replace with your app Name]

./gradlew -q :<app>:dependencyInsight --dependency aws-android-sdk-cognitoauth --configuration compile

Add below two lines in your build.gradle file under each of the compile library entries that has conflict.

Ex:

compile('com.xyz:abc:1.1.0-RELEASE') {
        exclude module: 'aws-android-sdk-cognitoauth'
        exclude group: 'com.amazonaws'
}

Not sure if sudo will help. Not sure if this help - https://stackoverflow.com/questions/17668265/gradlew-permission-denied – Rams_QA Jan 14 '18 at 01:11

Thanks everyone for your help! I was able to resolve this. I ended up only updating cognitoauth. Look at my edited post, I included my entire gradle. – portfoliobuilder Jan 16 '18 at 17:31

This problem occurs when importing both aws-android-sdk-cognitoidentityprovider and aws-android-sdk-cognitoauth, versions >= 2.6.6 and <= 2.6.13. This is because both of these libraries includes a jar that is common. Hence, the release builds (gradle assembleRelease task) would fail with an exception.

This was fixed in v2.6.14 where the underlying dependency has been made a separate library that these two libraries would depend on.
