# jenkins-post-receive
#
# Configuraton
# ------------
# jenkins-post-receive.enabled
#   [OPTIONAL] Defaults to off (false). Treated as a boolean with git config --bool.
#
# jenkins-post-receive.jenkins-cli-jar-path
#   [REQUIRED] Defaults to ""
#   This value should contain the full path to jenkins-cli.jar. Do not trust your path. Absolute paths work best.
#
#   Example:
#     git config jenkins-post-receive.jenkins-cli-jar-path "/usr/local/bin/jenkins-cli.jar"
#
# jenkins-post-receive.jenkins-url
#   [REQUIRED] Defaults to "".
#   This value should contain the url to jenkins.
#
# jenkins-post-receive.template-job-name
#   [OPTIONAL] Defaults to "#{jenkins.job-prefix}jenkins-post-receive-template"
#   The xml config of this job is used as the template for other jobs.
#
# jenkins-post-receive.job-prefix
#   [OPTIONAL] Defaults to "".
#   This value is used to prefix refnames as job names in jenkins.
#
#   Example:
#     If I set jenkins.job-prefix to 'my-repo-name-', jobs in jenkins will be
#     named like 'my-repo-name-master', 'myrepo-name-branch-foo', etc.
#

# Make sure we're enabled, and do nothing if we aren't.
# This is not an early exit, so that we can play nice
# in ConcatedHookScriptLandia.
