Automatic code coverage badge / reports for Java 8 project in Coveralls.io

Recently, I've setup a Java project hosted on Github to get automatically build using TravisCI. It's super cool to have a nice badge saying that your recent builds are green. But then I discovered I could have some more report using free tools like TravisCI.
For example - code coverage tool like Coveralls.io

This is where it got interesting quickly. It's written on the official site that it supports only dynamic languages but nothing about Java. But a quick search in Google pointed me to a maven plugin which connects with Coveralls' API. So I decided to give it a try.

Here are some useful links and hints for everybody trying to do it for his own project:

1. Check if your project is Java 8If it is, you have to use the JaCoCo maven plugin, since this is the only code coverage tool supporting Java8 compiled classes. Use at least version than 0.7.0  (according to this bug report)
   
   
2. Configure it your pom.xml to use JaCoCo
   You could use the snippet here but with newer JaCoCo version
   
3. Configure in your parent pom.xml to use coveralls-maven-pluginCarefully read the README of the plugin. For security reasons don't publish your token on your repo.
   
4. Update .travis.yml to try to upload your coverage report to Coveralls.io
   after_success: mvn clean test jacoco:report coveralls:jacoco
5. Add cool coverage badge to your README

   Congratulations!
   You've succesfully integrated: Github + TravisCI + Coveralls.io + JaCoCO for a Java 8 Project
   
   Check out my example project which has successfully integrated all these wonderful systems. https://github.com/leni-kirilov/MoneyTimer
   
   Kudos to Tapio Rautonen for creating such a useful plugin and documenting it in an excellent way!
