email-ext plugin stops without explication

[Xavier Raynaud]

Hi,

I'm using email-ext plugin on a post-build task of a FreeStyle project and sometime, emails are not send.

In order to understand why, I activate the "Enable Debug Mode" of this plugin.

I obtain the following output when all is OK:

18:05:27 Performing post-build step
18:05:27 Checking if email needs to be generated
18:05:27 Email was triggered for: Always
18:05:27 Sending email for trigger: Always
18:05:27 Sending mail from default account using custom from address to...@kalray.eu
18:05:27 messageContentType = text/plain; charset=UTF-8
[...]
18:05:27 DEBUG SMTP: message successfully delivered to mail server
[...]
18:05:27 Finished: SUCCESS

But from time to time, I obtain the following output, and... nothing more. The run just stops here.

17:55:17 Performing post-build step
17:55:17 Checking if email needs to be generated
17:55:17 Email was triggered for: Always
17:55:17 Sending email for trigger: Always
17:55:17 Sending mail from default account using custom from address to...@kalray.eu

I'm using jenkins 2.346.3 and email-ext 2.92

Any advice to debug this issue ?

Regards,
Xavier R.

Hello

i would recommend configuring a dedicated logger to capture more debug info from main Jenkins logs, something like:

This would give you more context about the email sending, and hopefully also during the failure.

Good luck

Hi,

I've done that, and after some time found the root cause.

Exception in thread "main" java.util.ServiceConfigurationError: jakarta.mail.Provider: Provider com.sun.mail.imap.IMAPProvider not a subtype
at java.util.ServiceLoader.fail(ServiceLoader.java:239)
[...]

Googleling a bit about this exception leads me to:

https://stackoverflow.com/questions/66224488/jakarta-mail-with-openjdk-11-java-util-serviceconfigurationerror-jakarta-mail

After that, it was simply solved by deinstalling unnecessary javax-mail plugin.
That's all folks !

Many thanks !
