Drush Make Non-existent project type on project metatags

Question

I am attempting to stream line the drush module DL process and it works great. The Issue though is many modules are getting the error:

Non-existent project type  on project metatags

I attempted to google this but does not seem to be a known error. Here is a copy of my make file (shortened)

;Use modules for Drupal 7
core = 7.x

;Drush api 2
api = 2

;Meta Tags
;http://drupal.org/project/metatags‎
projects[metatags][subdir] = contrib

;Also does not work with this:
;Views
;http://drupal.org/project/views‎
projects[] = views

Answer 1

That is correct the project metatags doesn't exist it's actually metatag. Also you need to specify a core version as well.

api = 2
core = 7.x
projects[drupal][version] = "7.21"

;Meta Tags
;http://drupal.org/project/metatags‎
projects[metatag][subdir] = contrib

;Views
;http://drupal.org/project/views‎
projects[] = views

Running the above I get a Drupal 7.21 install with sites/all/modules/views and sites/all/modules/contrib/metatag
