Composer revert packages
composer-php, git-revert, symfony, vendors
Solution
`composer install`, if you have kept your composer.lock file, will revert all your vendors to the previously installed state.
Problem
I am building a new app in Symfony 2.1. I am using a lot of bundles pulled in using composer. A lot of these bundles have problems with this latest version of Symfony and I am having to go into the /vendor folder to identify the issues. This means that I am changing the vendor files directly - purely for testing purposes. (When we have fixed a bundle we branch and submit appropriate pull request). What I want to know is if there is some command like `composer.phar revert` which would undo any changes made to the vendor folder (like a git checkout). At the moment if I run a composer `update` or `install`it does not do this. Thanks
