title: triggering builds of several items at once
body: <p>I have several items in Jenkins and I'd like to trigger a build in each one of them, once I hit build in a different item. I'd like it to happen in parallel.</p>
  <p>meaning - today I have item x, item y, item z.
  when I want to run them all together, I have to open a different tab for each one, and then hit the build button in each one, at once.
  now I'd like to have a different item, that when I hit the build button, it will trigger the builds in all of my items, and the builds of all the items will run simultaneously.</p>
  <p>how can I do that?</p>
