# Regular way to build a SonarSource Maven project on Travis.
# Requires the environment variables:
# - SONAR_HOST_URL: URL of SonarQube server
# - SONAR_TOKEN: access token to send analysis reports to $SONAR_HOST_URL
# - GITHUB_TOKEN: access token to send analysis of pull requests to GibHub
# - ARTIFACTORY_URL: URL to Artifactory repository
# - ARTIFACTORY_DEPLOY_REPO: name of deployment repository
# - ARTIFACTORY_DEPLOY_USERNAME: login to deploy to $ARTIFACTORY_DEPLOY_REPO
# - ARTIFACTORY_DEPLOY_PASSWORD: password to deploy to $ARTIFACTORY_DEPLOY_REPO

# deploy and analyze only on one axes of node versions
