A "json4s" dependency causes a build failure

[nikita-volkov]

Adding a org.json4s:json4s-jackson_2.11:3.2.11 dependency results in

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':packageDebug'.

Hi,

Please add following code to your build.gradle and try again.

android {
  packagingOptions { 
    exclude 'decoder.properties'
  }
}

Yes. I've worked around this by ending up with the following set up:

  packagingOptions {
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/NOTICE.txt'
    exclude 'decoder.properties'
    exclude 'rootdoc.txt'
  }

I just thought that it should be solved on the plugin level.

I agree with you. But this is official plugin's problem. See also: https://code.google.com/p/android/issues/detail?id=61573
