Slack plugin for Jenkins

  • Stability: Build Status
  • Slack: Slack Signup (click to sign up)

Provides Jenkins notification integration with Slack or Slack compatible applications like RocketChat and Mattermost.

Install Instructions for Slack

  1. Get a Slack account: https://slack.com/
  2. Configure the Jenkins integration: https://my.slack.com/services/new/jenkins-ci
  3. Install this plugin on your Jenkins server.
  4. Configure it in your Jenkins job (and optionally as global configuration) and add it as a Post-build action.

Install Instructions for Slack compatible application

  1. Log into Slack compatible application.
  2. Create a Webhook (it may need to be enabled in system console) by visiting Integrations.
  3. You should now have a URL with a token. Something like https://mydomain.com/hooks/xxxx where xxxx is the integration token and https://mydomain.com/hooks/ is the Base URL.
  4. Install this plugin on your Jenkins server.
  5. Configure it in your Jenkins job (and optionally as global configuration) and add it as a Post-build action.


Use Jenkins Credentials and a credential ID to configure the Slack integration token. It is a security risk to expose your integration token using the previous Integration Token setting.

Create a new Secret text credential:


Select that credential as the value for the Integration Token Credential ID field:


Bot user option

This plugin supports sending notifications via bot users. You can enable bot user support from both global and project configurations. If the notification will be sent to a user via direct message, default integration sends it via @slackbot, you can use this option if you want to send messages via a bot user. You need to provide credentials of the bot user for integration token credentials to use this feature.

Bot user option is not supported, if you use Base Url for a Slack compatible application.

Jenkins Pipeline Support

Includes Jenkins Pipeline support as of version 2.0:

slackSend color: 'good', message: 'Message from Jenkins Pipeline'

Additionally you can pass a JSONArray as a String in order to send complex messages, as per the example:

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
node {
    JSONArray attachments = new JSONArray();
    JSONObject attachment = new JSONObject();

    attachment.put('text','I find your lack of faith disturbing!');
    attachment.put('fallback','Hey, Vader seems to be mad at you.');

    slackSend(color: '#00FF00', channel: '@gustavo.maia', attachments: attachments.toString())

For more information about slack messages see Slack Messages Api and Slack attachments Api
