NullPointerException on failed build

[Alessandro Ferrucci]

I'm testing a build and when the build fails,it's supposed to send an email to a list of users.

I can see the NPE originating from the mail sender, and it would look like it would be because there are no recipients email addresses configured for the job, but I did configure email addresses.  I'm using latest stable Jenkins build (1.544)

Thanks!

NPE in the tokenizer could be misconfigured email addresses, too.

Marc,

that's what I thought, which takes me to a second issue.

I have configured a set of recipients in the job configuration.  When I click "Apply", then "Save", then go back to the job configuration, the email recipients are not saved (it's blank again).

So there's your problem; not sure how that got left out of the original report.  Figure out why your config isn't being saved, fix that, and try again.

[Alessandro Ferrucci]

Hi Marc,

thanks for your reply.

So I'm in the configuration screen of the job.  When I change any attributes other than E-Mail Notification Recipients, they get persisted to the job's config.xml.  Whenever I set any recipients, click Apply then Save, I open up the config.xml for the job, and the only thing I see in the reporters section is:

<reporters>
    <hudson.maven.reporters.MavenMailer>
      <dontNotifyEveryUnstableBuild>true</dontNotifyEveryUnstableBuild>
      <sendToIndividuals>false</sendToIndividuals>
      <perModuleEmail>true</perModuleEmail>
    </hudson.maven.reporters.MavenMailer>
  </reporters>

Obviously it's not persisting the changes to the config.xml, and I do not see any errors in the log file.

What are some other things I could check ?  FYI, I'm running in embedded/bootstrapped mode (java -jar jenkins.war), Not sure if that makes a difference or not.

Thanks!
