Filter culprits on email-ext

[Jon Schewe]

I use the email-ext plugin to send out emails about build failures. I originally had it set to send email to all culprits when the build failed. However I import some code from other repositories and then Jenkins wanted to send emails to people that weren't on my development team because of these imports. Is there a way to tell email-ext to only send email to a particular domain when picking the culprits?

No, culprits comes from Jenkins itself. The best you could do is have a presend script that modifies the MimeMessage's To list.

Which would need some custom Java code, correct?

Is there another plugin that might work?

No, you use Groovy for the pre-send script. There is no other plugin that I know of.

Oh, that doesn't sound too bad. Can you point me at some documentation and/or examples?

Thanks.

Information from the wiki [1]

Pre-send Script

The pre-send script is a feature which allows you to write a script that can modify the MimeMessage object prior to sending. This would allow adding custom headers, modifying the body, etc. Predefined variables include:

• msg - the MimeMessage object which can be modified
• logger - a PrintStream and will write to the job's log. 
• build - the build this message belongs to
• cancel - a boolean, which when set to true will cancel the sending of the email

so something like this:

recipients = msg.getRecipients(Message.RecipientType.TO)

filtered = recipients.findAll { addr -> !addr.toString().contains('@baddomain.com') }

msg.setRecipients(Message.RecipientType.TO, filtered)

Awesome, thanks!

For those that might want to do this themselves. I wanted to only send to gooddomain.com and not send anywhere else. Here is the script that worked. 

recipients = msg.getRecipients(javax.mail.Message.RecipientType.TO)

filtered = recipients.findAll { addr -> addr.toString().contains('@gooddomain.com') }

msg.setRecipients(javax.mail.Message.RecipientType.TO, filtered as javax.mail.Address[])

I added it to the Email-ext Recipes [1] page I created on the wiki.
