title: run multi job of multi jobs on jenkins
body: <p>I want to build multiple jobs in jenkins:</p>
  
  <p><img src="https://i.stack.imgur.com/Hg6Ye.png" alt="enter image description here"></p>
  
  <p>I install multi job plugin on jenkins. When I build <code>test_all_jobs</code>, it run job1 and freeze on it and doesn't start job1-1 until I close job1 test!</p>
  
  <p>Actually I want to start job1-1 then job 1-2 and after they finished job 2-1 then job2-2 should start.</p>
  
  <p>I should say I can not use Build Flow Plugin.</p>
  
  <p>Thanks.</p>
