# This template will build and test your projects as well as create the documentation.
#
# * Caches downloaded dependencies and plugins between invocation.
# * Verify but don't deploy merge requests.
# * Deploy built artifacts from master branch only.
# * Shows how to use multiple jobs in test stage for verifying functionality
#   with multiple JDKs.
# * Uses site:stage to collect the documentation for multi-module projects.
# * Publishes the documentation for `master` branch.

  # This will suppress any download for dependencies and plugins or upload messages which would clutter the console log.
  # `showDateTime` will show the passed time in milliseconds. You need to specify `--batch-mode` to make this work.
