A trigger script for the jenkins (hudson) email_ext plugin which informs users in case their commits introduce new violations or warnings. In contrast to the limit options of various other plugins for code analysis reporting this does not fail the build.A simple but insecure way to share this script between different jobs is to execute the follo…

Helpful code!
Using it in Post-build actions .. Editable Email Notification .. Advanced Settings .. Add Trigger .. Script .. Advanced .. Trigger Script.

One minor improvement to it is use

build = this.binding.build

instead of

build = Jenkins.instance.items[0].builds[0]

Works even if we create new jobs copying current settings.
