I would like to use something like FileUtils.uptodate?(''last-update'', ''pom.xml'') to trigger an action like ''mvn dependency:copy-dependencies'' before some rails commands like server, console, runner and tasks. This would copy the Maven dependencies in a JRuby on Rails project whenever the dependencies are changed. This wouldn''t work for SNAPSHOT changes but that is ok for me, since I would have another specific task for this. But the question is: how to trigger those actions? I instantly thought in putting this in Gemfile, but maybe there is a better way for dealing with this situation in Rails 3. Is there?
