# All environment variables used are passed from either Travis or docker-compose.
# See details at https://docs.sonarqube.org/display/SONAR/Analysis+Parameters.
#
# Travis ones are:
# Created by us:
# - SONAR_ORG - SonarCloud "organization", under which the project is located.
# - SONAR_PROJ_KEY - SonarCloud project key (name) to report to.
# - SONAR_TOKEN - access token for that project (must be protected in Travis).
# - GITHUB_TOKEN - GH OAuth token used by SonarCloud's GH plugin to report status in PRs.
# See details at https://docs.sonarqube.org/display/PLUG/GitHub+Plugin. Must be protected.
# Default:
# - All TRAVIS_* variables. They are described in Travis docs
# at https://docs.travis-ci.com/user/environment-variables

# docker-compose ones are:
# - MRAA_SRC_DIR - path to mraa's git clone in the Docker container.
