I have a declarative pipeline job. The Jenkinsfile has the following snippet:
step([$class: 'Mailer', recipients: 'email@example.com', sendToIndividuals: true])
When the build fails, the addresses in the recipients string successfully receive mail. However the culprits responsible for the broken commit do not receive an individual email. As I have set the sendToIndividuals, I expect that they would. I've been unable to find any logs that might suggest a misconfiguration.
I have been able to workaround this issue with the mail-ext plugin by changing the above snippet to:
recipients: ['firstname.lastname@example.org', emailextrecipients([[$class: 'CulpritsRecipientProvider'], [$class: 'RequesterRecipientProvider']])].join(' ')
But I had hoped that this would work without introducing another plugin.
