# To contribute improvements to CI/CD templates, please follow the Development guide at:
# https://docs.gitlab.com/ee/development/cicd/templates.html
# This specific template is located at:
# https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Maven.gitlab-ci.yml

# Build JAVA applications using Apache Maven (http://maven.apache.org)
# For docker image tags see https://hub.docker.com/_/maven/
#
# For general lifecycle information see https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

# This template will build and test your projects
# * Caches downloaded dependencies and plugins between invocation.
# * Verify but don't deploy merge requests.
# * Deploy built artifacts from master branch only.

  # `showDateTime` will show the passed time in milliseconds. You need to specify `--batch-mode` to make this work.

  # As of Maven 3.3.0 instead of this you MAY define these options in `.mvn/maven.config` so the same config is used
  # when running from the command line.
  # As of Maven 3.6.1, the use of `--no-tranfer-progress` (or `-ntp`) suppresses download and upload messages. The use
  # of the `Slf4jMavenTransferListener` is no longer necessary.
  # `installAtEnd` and `deployAtEnd` are only effective with recent version of the corresponding plugins.

# This template uses the latest Maven 3 release, e.g., 3.8.6, and OpenJDK 8 (LTS)
# for verifying and deploying images
# Maven 3.8.x REQUIRES HTTPS repositories.

# Be aware that `mvn deploy` will install the built jar into this repository. If you notice your cache size
# increasing, consider adding `-Dmaven.install.skip=true` to `MAVEN_OPTS` or in `.mvn/maven.config`
