title: The current build parameters/ENV Variables in different build steps
body: <p>Is it possible to define a new build parameter/ENV variable in a build step so it was available in the next one?</p>
  
  <p>Let's say I have 2 different "Execute shell" steps and want in the second step access the variable defined in the first one.</p>
  
  <p><strong>PS</strong>: the value for the variable is set in runtime - read from 3rd party resource, so I cannot harcode it, thus need to set it from the shell script.</p>
