how Duplicate Zip Entry after Gradle Plugin v0.13.1



I’ve been using the Gradle Android plugin v0.12 but I decided to upgrade to the new version, because I needed the new functionality (and the improved speed is always a plus).

After updating to the new v0.13.1, I keep getting the “Duplicate Zip Entry” (from Proguard) while everything worked before. The full error: Can’t write [/Users/…/classes-proguard/netherlands/release/classes.jar] (Can’t read [/Users/…/.gradle/caches/modules-2/files-2.1/org.apache.commons/commons-io/1.3.2/b6dde38349ba9bb5e6ea6320531eae969985dae5/commons-io-1.3.2.jar(;;;;;;!META-INF/MANIFEST.MF)] (Duplicate zip entry [commons-io-1.3.2.jar:org/apache/commons/io/CopyUtils.class])) (CopyUtils was FileUtils before).

I’m using following packaging options: packagingOptions

   exclude 'AndroidManifest.xml' 
   exclude 'META-INF/notice.txt' 
   exclude 'META-INF/license.txt' 
   exclude 'META-INF/LICENSE.txt' 
   exclude 'META-INF/NOTICE.txt' 
   exclude 'META-INF/MANIFEST.MF' 
   exclude '!META-INF/MANIFEST.MF' 
   exclude 'META-INF/services/javax.annotation.processing.Processor' 

As you can tell, I’m excluding the manifest files…

Just to test it, I changed back to version 0.12.0 and everything works again, back to 0.13.* and it breaks (but I need 0.13.*)!

Further, I’m using the following libraries:

  1. Robospice
  2. Retrofit
  3. OkHttp
  4. Dart
  5. Icepick
  6. Butterknife
  7. Crouton
  8. SmoothProgressBar
  9. NineoldsAndroid (in library of BetterPickers)

Did anyone encounter this issue too? If so, can anyone please help me out (been breaking my head for 2 days on this issue now!)? Thanks!





I had the same issue when updating to Android Gradle plugin 0.13. I managed to fix it by including retrofit this way in my build.gradle file:

compile('com.squareup.retrofit:retrofit:1.6.1') {
    exclude group: 'commons-io', module: 'commons-io'

Edit: And can do this on all retrofit and robospice dependcies at once with:

compile('') {
    exclude group: 'commons-io', module: 'commons-io'

It will get all underlying dependencies automatically (retrofit, robospice-core, robospice-cache, …).
