I use Jenkins (v1.578) with promoted-build (v2.19) and mail-ext (v2.38.2) plugins.
I would like to use the ${CHANGES_SINCE_LAST_SUCCESS} in an email sent as an Action after the promotion succeeded.
At the moment I get a blank value for ${CHANGES_SINCE_LAST_SUCCESS}, I suspect this is related to the way the promoted-build plugin work (seems to create a new job for the promotion which does not have any changes)
Is it possible to use a specify key or even use the groovy template to retrieve data from the original build ?
EDIT: My final goal would be to notify some people that a new release has been deployed in the staging environment, idealy the email should contain all the changes since previous deploy (=Since last success).
