module: jenkins_script
short_description: Executes a groovy script in the jenkins instance
description:
    - The C(jenkins_script) module takes a script plus a dict of values
      to use within the script and returns the result of the script being run.

attributes:
  check_mode:
    support: none
  diff_mode:
    support: none

options:
  script:
    type: str
    description:
      - The groovy script to be executed.
        This gets passed as a string Template if args is defined.
    required: true
  url:
    type: str
    description:
      - The jenkins server to execute the script against. The default is a local
        jenkins instance that is not being proxied through a webserver.
    default: http://localhost:8080
  validate_certs:
    description:
      - If set to V(false), the SSL certificates will not be validated.
        This should only set to V(false) used on personally controlled sites
        using self-signed certificates as it avoids verifying the source site.
    type: bool
    default: true
  user:
    type: str
    description:
      - The username to connect to the jenkins server with.
  password:
    type: str
    description:
      - The password to connect to the jenkins server with.
  timeout:
    type: int
    description:
      - The request timeout in seconds
    default: 10
  args:
    type: dict
    description:
      - A dict of key-value pairs used in formatting the script using string.Template (see https://docs.python.org/2/library/string.html#template-strings).

notes:
    - Since the script can do anything this does not report on changes.
      Knowing the script is being run it's important to set changed_when
      for the ansible output to be clear on any alterations made.
