Jenkins email-ext plugin thinks I have no recipients configured

Question

I'm using Jenkins 2.2 and email-ext plugin 2.42 (both current, as are all of the rest of my plugins). I have my global configuration set to have a single, explicit recipient and my project is using default email notification configuration (that is, send to $DEFAULT_RECIPIENTS). I have also set an explicit recipient in the project. In both configurations, the console output for the job says:

An attempt to send an e-mail to empty list of recipients, ignored.

This would seem to be https://issues.jenkins-ci.org/browse/JENKINS-13583 except 1. that was marked as resolved four years ago, and 2. I get e-mail when I use basic, built-in notifications. Does anyone else see this problem with email-ext?

Answer 1

Turns out plugin configuration is somewhat non-intuitive; a necessary setting is buried behind an Advanced button. I got answers in https://issues.jenkins-ci.org/browse/JENKINS-34731 and it is working now as follows:

In the Advanced settings, Triggers -> Failure - Any lists "Developers" by default, but not "Recipient List."

Answer 2

For those using this plugin in combination with Job DSL. I have do add the sendTo { recipientList() } block explicitly to the different triggers.

So my DSL looked like this:

extendedEmail {     recipientList('${EMAIL_RECIPIENTS}')     triggers {         failure {             subject('The subject')             content("The content")             sendTo {                 recipientList()             }         }     } }
