We're running Jenkins with the Slack Notification Plugin. Is there a way to send the custom message only on completion, not on start? To be clear, I don't want to disable the build started message, I'd just like the custom text to only show on completion (success).
Use case is jobs like delete stack. We use the custom message to make it clear which stack the job deleted, but you end up with slack messages like (paraphrased)
Delete job started Deleted Alex stack Delete job finished Deleted Alex stack
Obviously you can see where this causes confusion. I'd rather get
Delete job started Delete job finished Deleted Alex stack
"It can't be done" is an acceptable answer if that's the case. I know I can do a pipelines workaround but I'd love a quick fix for the jobs we haven't converted yet.
