# This script runs a Sonarqube analysis for a Gerrit plugin and uploads the
# results to the local Sonarqube instance, similar to what `mvn sonar:sonar`
# would do.
#
# It will build the plugin, generate sonar-project.properties file and then
# call sonar-scanner (sonar-scanner must be installed and available in the
# path).
#
# This script must be called from the root folder of a gerrit plugin supporting
# standalone bazel build:
#
# ./bazlets/tools/sonar.py
