defmodule Mix.Tasks.Ca.Release do
  @moduledoc """
  Run common static code analysis tools and tests for the project
  Run mix release and move compressed artifact to _build/release/artifact folder

  Examples:
      $ mix ca.release

  It generates the following files:
  * _build/release/credo_sonarqube.json
  * _build/release/excoveralls.xml
  * _build/release/generic_test_execution_sonarqube.xml
  * _build/release/sobelow.json
  * _build/release/sobelow_sonarqube.json
  * _build/release/test-junit-report.xml
  * _build/release/artifact/<app-name>.tar.gz

  You can skip some task with --skip-test or --skip-release options:
      $ mix ca.release --no-test
      $ mix ca.release --no-release

  You can run the tasks inside a container with --container option:
      $ mix ca.release --container

      this uses the following configuration:
      * container_tool: docker
      * container_file: Dockerfile-build
      * container_base_image: 1.16.2-otp-26-alpine

      You can change the configuration in config/config.exs with:

      config :elixir_structure_manager,
        container_file: "Dockerfile-build",
        container_base_image: "1.16.2-otp-26-alpine",
        container_tool: "docker"
