What version of the git plugin are you using?

Also, that email address may already have been defined for the user in Hudson - check the user's configuration. If there's already an email address defined for (using your git whatchanged example) "Geir Gullestad Pettersen", then the git plugin isn't going to try to create a new one - the existing one is used.

I'm having the same problem. Using Hudson 1.371 and version 1.0.1 of the Git plugin. This is what I see in the Hudson job console output:

Failed to send e-mail to Andy Goldstein because no e-mail address is known, and no default e-mail domain is configured

Here is the output of "git whatchanged"

commit 1d73cacddab106c23840834bfb29bfccfd0081e2
Author: Andy Goldstein <[email address obscured, but it's my correct email address]>

Have you checked what email address is set up for your user in Hudson?

I haven't configured authentication/users in Hudson. I was hoping it would just pick up the author (or committer) address from the Git commit. Can it not do that?

It should - I'll try to reproduce this locally and see what I can figure out.

Thanks, I look forward to hearing back what you discover. If it makes any difference, the "people" in Hudson were added to the system when I had version 0.9.2 of the Git plugin installed. Maybe that version had issues with figuring out the email address? I clicked on the People link in Hudson, clicked on my user, then on Configure, and my email address is currently blank.

Ah-ha - I don't know for sure whether the user (i.e., the "people" entry) email address was borked in 0.9.2, but if the user already exists, it does tend to have problems setting the email address automatically from the git changelog. So you can fix this as a one-off by entering an email address for your user, but I'll keep trying to figure out what's really going wrong.

hello people,

I guess i found the problem here, here is the git log output from my host:

commit cf566f1b17ff280c4bda9af4da7547110cf1fe0c
Author: Andrew Bayer <abayer@digg.com>
Date: Fri Sep 17 11:10:26 2010 -0700

it seems to be different from the one expected in the source code, which is
author xxx xxx <xxx@bbb.com> 1231213131 -12121

Actually, the plugin is running this command to get the change log:

git whatchanged --no-abbrev -M --pretty=raw

which matches the regexp-es.

I see this as well, are there any tips on how we can debug this? If I could debug it, perhaps I could submit a patch to fix it.

I think I've managed to figure out the issue:

http://hustoknow.blogspot.com/2011/01/hudson-git-plug-in-issues.html

Changing the code to this part in GitChangeSet.java worked:

if (fixEmpty(csAuthorEmail) != null ) {
try

catch(IOException e)

}

The issue appears to be that when User() is first initialized, all the UserProperties are also init. For Git committers that don't have explicit accounts, this Mailer.UserProperty() is set to null, causing the e-mail address not to be set.

The fix above makes the Git commit message the highest priority for resolving e-mail addresses. Using both the getProperty() check, or the getProperty() and getAddressInfo() causes problems as described in the blog entry.

I reported the same problem on the dev mailing list because also the ci.jenkins-ci.org installation has the same problem.
I was wondering if it is possible to retrive the e-mail address (if configured) from github?

this is my git configuration where I explicitely set my email address:

$ git config -l
github.user=mambu
user.name=Marco Ambu
user.email=MYEMAIL@gmail.com

Bug still exists on Hudson ver. 1.391 (private-01/13/2011 16:10-vjuranek).

I presume this issue is now fixed.

Maybe not. I just tried this snapshot from the trunk, and while it stopped sending email to the full name, it seems to be resolving the addresses to nothing now. The author lines in changelog.xml are in the proper format with full name, email, timestamp, and TZ. The user/Full Name/configure page also has the email address somehow, so even if that's overriding, it doesn't explain why the recipient list is empty.

Never mind. It worked after I actually checked "Send separate e-mails to individuals who broke the build". Sorry.

There is still an issue with this where the git plugin somehow overrides the mailing address if there are git-svn repos. See JENKINS-13715

git plugin now only set email address if not already set for User
