Hello, I found a bug while trying to making work StopwatchTask with Phar version of Phing. You can see the details in another issue: #1053 (comment)

So I added symfony/stopwatch with Composer, and then used AutoloaderTask to load vendor/autoload.php.

These are the results:

• Phing 2.16.1: Works well
• Phing 3.0.0-alpha1: Works well but I think it's because Phar file already includes all required dependencies, therefore AutoloaderTask is not needed.
• Phing 3.0.0-alpha2: Error, I have the following message:

  Dependencies missing in PHAR > stopWatch:
