Drush Make for a custom module hosted at github I am trying to fetch a custom module versioned at github.com via drush make, but I get 

Could not retrieve version information for custom_migration 
Non-existent project type  on project techarena_migration 


My drush make file section for the custom module is the following:

projects[custom_migration][subdir] = "custom"
projects[custom_migration][type] = "module"
projects[custom_migration][download][type] = "git"
projects[custom_migration][download][url]="git@github.com:qed42/custom_migration.git"


I also tried giving the branch parameter, but no change 

projects[custom_migration][download][branch] = "master"


This is a private repository, could it be that?

Update: I am so sorry, I was using the wrong makefile. Sorry to have wasted your time. I am not sure if I should close the question? 

P.S git:// doesn't work with private repo on github, git@github.com does!!
According to the documentation, you have to write the download url line this way:

projects[mytheme][download][url] = "git://github.com/jane_doe/mytheme.git"
