Email-ext plugin - dynamically modifying the recipient list

[Bob Bick]

Hi,

 

We are using the Email-ext plugin 2.24.1 to send out email notifications. Overall, it works great; however, I was given a new requirement:

 

·         Send out email notifications to a list of users if the build is a “release build”. More specifically, there is a Boolean RELEASE_BUILD Job parameter that controls whether the build is a “release build” and there is a RELEASE_BUILD_EMAIL_DISTRIBUTION parameter that contains a list of users. If the RELEASE_BUILD Job parameter is “true”, then RELEASE_BUILD_EMAIL_DISTRIBUTION users should also receive the email notification.

 

I tried to use the Pre-send Script to change the recipient list dynamically. However, the Pre-send Script does not get invoked if there are no recipients.

 

My “brute force” solution was to put a dummy email account as the recipient (so that the Pre-send Script would always get invoked); and then use the Pre-send Script to change the recipient list dynamically. But, I really don’t like this hacked solution since emails are always being sent to a dummy email account.

 

Q. Has anyone else ever had a similar requirement? If so, did you find a better solution?

 

Thanks in advance,

 

Bob

The email-ext plugin will check if the recipient list is empty before trying to send the email (which is where the pre-send script is executed). Putting a dummy address in is currently the only way you would be able to achieve what you want to do.

Thanks for the quick response. I was afraid that that was the only solution L

You can always file a JIRA on it, I am not sure of the mechanics of changing the location of the execution of the pre-send script since I can't look at the code right now, but its something that could possibly be changed.

Hi.

You can use a groovy template in the recipients list to modifying the recipients list. The last line of your script should return a string with all the recipients.
For examples, you can have a file recipients.template:

<%
def authors = "m...@example.tld"

if (build.environment["RELEASE_BUILD"]) {
    authors = build.environment["RELEASE_BUILD_EMAIL_DISTRIBUTION"]
}
%>

${authors}

The recipients should be comma separated.

And in your jobs configuration, in the recipients list, you put ${SCRIPT, template="recipients.template"}

You can also just use a groovy script, ${SCRIPT, script="yourscript.groovy"}
