[JENKINS-62596] Email functionality is not working after Jenkins upgrade

[timja]

Hi Team,

On 16/May/2020, we upgraded our jenkins from 2.165 to 2.236 version. After upgrade, we are getting an exception while sending an email after build Failure in Jenkins. It was working fine before upgrade.

Below is the exception message from jenkins console log. Please check this asap and resolve. Let us know if any details needed. Thanks.

 

Exception:

jsanthoshkumarj:

The issue is with emails not getting triggered when there is a job failure. Emails are flowing for success scenarios. As part of debugging, we have tried the following:

• Reproduced the issue by manually failing a success job
• Configured the global missing parameters based on the exceptions we saw in log
• Reverted the email related plugin to previous version and restarted the Jenkins instance

This is not an issue with email-ext. It looks like it would be the maven plugin.

I upgraded Jenkins yesterday & am seeing a similar stacktrace, but its not involving the maven plugin...

alfabravoteam:

It's an odd message because it seems to fail while building an empty message and trying to set the 'from' value with a null value. And the normalized value for that field would only be null if you set something that is not an email address and you don't have a default suffix configured.

andrewn:

Same issue here. Thanks to Andres’s comment, as a workaround, I set a value for “Default user e-mail suffix” under “E-mail Notification” (not “Extended E-mail Notification”) on https://jenkins.example.org/configure, and jobs are sending email again.
