title: Check if two antcalls are successfull
body: <p>I'm extremely new to ant script and i want to find out if my build is successful or not. my main target has two antcalls and i don't know how to check if they were successful or not, in order to evaluate the main target.</p>
  
  <p>run all is my main target</p>
  
  <pre><code>&lt;target name="run all"&gt;
  &lt;antcall target="Run basic configuration" /&gt;
  &lt;antcall target="Run custom configuration"/&gt;
  </code></pre>
  
  <p></p>
  
  <p>i want to add a fail condition for the "run all" target.
  Each target does check individually if they are successful, but I want to know if the target that calls the ant is unsuccessful in case those two fail.
  Also, if one fails does the other one get called?</p>
