ot-clean, Coveralls integration and code cleanup

I had hard time integrating Cobertura and coveralls. In the end it turns out it’s just not working and I’m continuously fighting with errors. Moreover, Cobertura is really crashing a lot in JDK 8. I found however very interesting and active test coverage project called Jacoco. Below you can find coverage profile I am using in order to produce coverage report and send it to


I am using Travis for building purposes. Below you can find configuration file:

language: java
 - oraclejdk8
   - $HOME/.m2
 - mvn clean install -Pqulice,coverage coveralls:report --batch-mode --errors

Recurrence -r parameter is gone

One small update regarding version 0.8. It turns out that I’ve never wanted to use cleanup only on the current directory. Therefore -r parameter has been removed in 0.8 and now by default application is looking for all nested directories.
