[FIXED] Jenkins slackSend: channel alert notifications for @here or specific user

Issue

Jenkins slackSend question: How to perform an alert notification to a channel that has received a message that needs to be addressed by either any member @here or a specific person ex @Jane.Doe?

Reviewed Jenkins Slack notifications: https://www.jenkins.io/doc/pipeline/steps/slack/

Tried adding @here to the beginning of slackSend message:

failure {
    script {
        slackSend(
            color: "#FF0000",
            channel: "${SLACK_CHANNEL}",
            message: "@home FAILED"
        )
    }
}

However, adding @here to slackSend message does not initiate alert notification for that channel.

Suggestions?

Note: Received a comment from a coworker, I am investigating this path:

thought I remember needing to do a look up on users to get an ID and then some special syntax it parses into a username. been a while though.

Solution

First you must find the ID of the user and then mention it in the the message, like this example:

def userId = slackUserIdFromEmail('[email protected]')
slackSend(color: "good", message: "<@$userId> Message from Jenkins Pipeline")

Edit:

If you want a put a special or a group mention, you only need follow the format guideline what can you see here : https://api.slack.com/reference/surfaces/formatting#special-mentions
