ubuntu - jenkins自动构建laravel 4时，phpunit执行时vendor/autoload.php报语法错误

在同一个环境下，php在终端使用ant构建项目执行phpunit测试没有问题，但是在jenkins自动构建时会报错：
<br> phpunit:<br> [exec] PHP Parse error: syntax error, unexpected ' [exec] PHP Stack trace:<br> [exec] PHP 1. {main}() /usr/local/bin/phpunit:0<br> [exec] PHP 2.

autoload.php的代码：
<br><?php <br> // autoload.php @generated by Composer<br> require_once <strong>DIR</strong> . '/composer' . '/autoload_real.php';<br> return ComposerAutoloaderInit34c7d9c593778809996626035f6ae5ee::getLoader();<br>

<target name="phpunit" description="Run unit tests with PHPUnit">
    <exec executable="phpunit" failonerror="true">
        <arg value="-c" />
        <arg value="${basedir}/phpunit.xml.dist" />
        <arg value="--coverage-html" />
        <arg value="${basedir}/build/coverage" />
    </exec>
</target>

为什么会这样，哪里有问题？
