When using Drush make keep the .git for component from git

When using Drush make for download the component for your Drupal distribution you probably need libraries/modules/themes from git. The problem is that the .git folder is deleted and this is a problem when you need to apply patches or pull updates for those components.

You can solve by adding --working-copy to your drush make command:

drush make --no-core --working-copy=TRUE --contrib-destination drupal-org.make .
