Jenkins isn't sending email, also saw NoClassDefFoundError: hudson/tasks/Mailer

XMLWordPrintable

      Jenkins has stopped sending emails. In the Config for builds, under Post-Build Actions > Editable Email Notification, an ERROR link when clicked shows the following error:
      javax.servlet.ServletException: java.lang.NoClassDefFoundError: hudson/tasks/Mailer

      Build success emails are not coming through either, though console output for the build says email was triggered: "Email was triggered for: Success
      Sending email for trigger: Success"

          Sounds like you don't have the Mailer plugin installed or enabled.

          I don't think that email-ext is the cause of your issue. The stack trace in the configure page shows nothing about email-ext, its all about the Mailer. Also, if Mailer is not available because of some issue, emails will not be sent, so I'd look at why the Mailer plugin is causing you an issue.

          Odd because I can send test mails without issue. Why would that error show up below the Project Recipients List? I removed $DEFAULT_RECIPIENTS and did Apply and Save and now I don't see that error anymore.
