# This file is a template, and might need editing before it works on your project.
---
# 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 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.

stages:
- verify-project
- test
- build_image

  # 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.

  # As of Maven 3.3.0 instead of this you may define these options in `.mvn/maven.config` so the same config is used

# This will only validate and compile stuff and run e.g. maven-enforcer-plugin.
# Because some enforcer rules might check dependency convergence and class duplications
# we use `test-compile` here instead of `validate`, so the correct classpath is picked up.
