Symfony2 updating bootstrap.php.cache

In the 2.0 release the original file is here:

./vendor/bundles/Sensio/Bundle/DistributionBundle/Resources/bin/build_bootstrap.php

Edit: in release 2.3 the file is here

vendor/sensio/distribution-bundle/Sensio/Bundle/DistributionBundle/Resources/bin/build_bootstrap.php

If you run the composer update command you will also update your project dependencies which is not the desired behaviour here. If you do that you'll have to test the new changes to see if they do affect your application somehow.

So if you just want to rebuild your bootstrap cache file then I suggest you run the post-update-cmd command.

Therefore you should use:

composer run-script post-update-cmd

which in my case executes the following scripts (see composer.json):

"scripts": {
    "post-install-cmd": [
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile",
        "Mopa\\Bundle\\BootstrapBundle\\Composer\\ScriptHandler::postInstallSymlinkTwitterBootstrapSass"
    ]
}

Please consider that you can also create a new set of scripts in there to just rebuild the bootstrap file and clears the cache without installing the assets and so on:

"scripts": {
    "reset-bootstrap-cmd": [
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache"
    ]
}

and then... composer run-script reset-bootstrap-cmd
