Integrating Travis, SonarQube and GitHub

Overview

This setup is not documented yet, so these services may change it at anytime

The main trick here is to use the sonarqube Travis add-on that will set up the proper environment variables the key one being SONARQUBE_SCANNER_PARAMS that will contain the token and the host URL so you do not have to explicitly put in $SONAR_TOKEN in the script section. In addition, if the add-on detects that it is a pull request it will set the parameters used for SonarQube GitHub Plugin.

This is triggered by having two secure environment variables defined in your build containing your tokens:  SONAR_GITHUB_TOKEN and the token put directly into the addon: sonarqube: token:.

Then all you would need is to execute mvn sonar:sonar in your script to get everything working.
