Proguard Duplicate Zip Entry

Question

I am trying to run my android application through Proguard, however this keeps appearing:

Warning:Exception while processing task java.io.IOException: Can't write [C:\Users\Aliaksei\AndroidStudioProjects\SignOutSystem\app\build\intermediates\transforms\proguard\debug\jars\3\1f\main.jar] (Can't read [D:\Users\Aliaksei\.android\build-cache\f7a6034d02d095f18cc21950f131d07fa78b41c0\output\jars\classes.jar(;;;;;;**.class)] (Duplicate zip entry [android/support/v4/os/j.class == classes.jar:android/support/v4/os/ResultReceiver$MyResultReceiver.class]))

I am aware that this means that the android.support.v4 is being declared twice somewhere, so I have tried adding exclude group: 'com.android.support', module: 'support-v4' to any possible dependencies that might have it included, however that didn't work, even after a clean and rebuild.

Thinking I must have missed a dependency somewhere, I proceeded to add it to everything (Overkill), but that still hasn't worked.

Searching around, I found this snippet in similar posts and added this in the android section as well:

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
}

I have run out of ideas and searching for answers seems to take me to things I have already tried. Anything I'm missing?

Answer 1

The issue is butterknife which is compiled with a higher support version (25.1.0), so you may want to downgrade butterknife or move all support library to 25.1.0

Here I've downgraded butterknife to 8.0.1 :

dependencies {
    compile('com.google.api-client:google-api-client-android:1.22.0') {
        exclude module: 'httpclient'
    }
    compile('com.google.apis:google-api-services-sheets:v4-rev19-1.22.0') {
        exclude module: 'httpclient'
    }

    compile 'com.google.android.gms:play-services-identity:9.2.0'
    compile 'com.google.android.gms:play-services-auth:9.2.0'

    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support:percent:23.4.0'

    compile 'com.squareup.okhttp3:okhttp:3.3.1'
    compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'
    compile 'com.squareup.okio:okio:1.8.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'net.sf.biweekly:biweekly:0.4.6'
    compile 'com.github.tibolte:agendacalendarview:1.0.4'
    compile 'com.7heaven.widgets:segmentcontrol:1.14'
    compile 'com.survivingwithandroid:weatherlib:1.6.0'
    compile 'com.survivingwithandroid:weatherlib_okhttpclient:1.6.0'
    compile files('libs/FDxSDKProAndroid.jar')
    debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5'
    releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5'
    testCompile('com.squareup.leakcanary:leakcanary-android-no-op:1.5')

    compile 'com.jakewharton:butterknife:8.0.1'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.0.1'
}

Then in your proguard.pro to deal with warning :

 -keep class com.fasterxml.** { *; }
 -dontwarn com.fasterxml.**

 -keep class biweekly.io.json.** { *; }
 -dontwarn biweekly.io.json.**

 -dontwarn java.lang.invoke**

 -dontwarn sun.misc.Unsafe

 -dontwarn okio.**

Note that I've also enabled multidex to build successfully : I've added multiDexEnabled true to defaultConfig
