This plugin allows users to send build notifications to a self-hosted Mattermost installation.

It is based on a fork of the Slack plugin: https://github.com/jenkinsci/slack-plugin/

The Slack plugin was a fork of the HipChat plugin: https://github.com/jlewallen/jenkins-hipchat-plugin

Which in turn, was a fork of the Campfire plugin.

It includes Jenkins Pipeline support as of version 2.0:

mattermostSend color: 'good', message: 'Message from Jenkins Pipeline', text: 'optional for @here mentions and searchable text'

1. The first step is to set up a Mattermost server
2. Then Configure an incoming webhook
3. Install this plugin on your Jenkins server
4. Add it as a Post-build action in your Jenkins job.
