Building applications with Symfony Console, Disco and box2

Building applications with Symfony Console, Disco and box2

In the past few weeks I built a few cli applications with Symfony Console and Disco, the DI container we open sourced last year. I wanted to figure ouf if we run into issues with Disco that we need to work on. The main script looks like this:

try {
    $cache = new \Doctrine\Common\Cache\VoidCache();
    $beanFactory = new \bitExpert\Disco\AnnotationBeanFactory(

    /** @var \Symfony\Component\Console\Application $app */
    $app = $beanFactory->get('cliApplication');
} catch (\Exception $e) {
    echo $e->getMessage() . PHP_EOL;
    exit 1;

Calling the script from the console worked without any problems. Next up was trying to build a .phar file out of the sourcs. To help me build the .phar file I tried box. Building the .phar file was easy, but when i tried to run the generated .phar file I got the following error from Disco:

"\MyApp\CliConfiguration" seems not to be a valid configuration class. 
@Configuration annotation missing!

It was clear to me that somehow the docblock comments got stripped out when the .phar file was built. As it turns out I was using the default box.json.dist file which contains a so-called compactor configuration. Compactors like the \Herrera\Box\Compactor\Php are trying to reduce the size of the source files by stripping whitespaces or comments. The "fix" was simple: I removed the compactors definition from the box.json.dist file, rebuilt the .phar file and was able to run it without any further problems.
