title: Jenkins: how to make parameters required in a parameterized build?
body: <p>In Jenkins is there a plugin for parameterized builds to make the parameters required?  The fields under the standard "This build is parameterized" option do not seem to provide that.</p>
  
  <p>Clarification: by "required" I mean that the build will not execute until the field is populated with a value.  This would obviously preclude automated triggers.</p>
