title: How to send e-mail to upstream committers if downstream job fails?
body: <p>We have 2 projects in Jenkins.
  1. Project-A
  2. Tests</p>
  
  <p>Tests is a downstream job for Project-A. Currently, if some change in Project-A breaks Tests job, there is no e-mail sent to culprits (those who made changes in Project-A).</p>
  
  <p>I want to send a mail to all those upstream committers if my downstream job (Tests module) fails. How can we do it?</p>
  
  <p>Thanks</p>
