title: Jenkins Build Confirmation
body: <p>i have some build with prarameters and one of the parameter is environment[it will show 3 drop down options].</p>
  
  <p>i want to make sure that user selected correct env to deploy</p>
  
  <p>is there any way in jenkins once the user selected build with parameters and then it will ask for confirmation like</p>
  
  <pre><code>    Are you sure you want to deploy to prod env yes or no
  </code></pre>
  
  <p>if yes it will continue build and no if shouldn't trigger build</p>
  
  <p>Any idea on this approach</p>
  
  <p>Thanks</p>
