title: TeamCity command line permission denied
body: <p>I put up a vagrant box with teamcity. Everything works but when I add a command line build step, which contains 'drush cc all' I get this error:</p>
  
  <p>Cannot run process: Cannot run program "/vagrant/public/TeamCity/buildAgent/temp/agentTmp/custom_script1106304414420673073" (in directory "/vagrant/public/dev"): java.io.IOException: error=13, Permission denied</p>
