Ubuntu-jenkins Automatic Build Laravel 4 o'clock, phpunit vendor/autoload.php report syntax error at execution time

In the same environment, PHP does not have a problem using the Ant build project in the terminal to perform the PHPUnit test, but it will error when Jenkins builds automatically:

Autoload.php's Code:

// autoload.php @generated by Composer
require_once DIR . '/composer' . '/autoload_real.php';
return ComposerAutoloaderInit34c7d9c593778809996626035f6ae5ee::getLoader();


The following paragraph is the code snippet for Build.xml:

Why is this, where is the problem?
