Using a specific branch of a meteorite package

Question

How do i specify or change the version of a package i want to use with atmosphere? Can i pass in the git branch to my smart.json file as an option ? Something like this in the smart.json file ? I would like to run off of a git version and have meteor grab and use that version when running the application.

Here is what i have tried doing which errors with version does not exist

"packages": {

     iron-router: {
        version: {"https://github.com/EventedMind/iron-router/tree/dev"} 
     }

   }

Answer 1

Edited per comment below (don't leave this on dev!!! but things are changing quickly):

iron-router: {
    "git": "https://github.com/EventedMind/iron-router" ,
    "branch": "dev"
  }
}

Have you tried this syntax?

iron-router: {
    "git": "https://github.com/EventedMind/iron-router/tree/dev" ,
    "branch": "master"
  }
}

Answer 2

wanted to install iron-router-progess too, didn't allow me to do that with the master branch so I had to remove iron-router, change smart.json to

{
  "packages": {
    "bootstrap-3": {},
    "iron-router": {
      "git": "https://github.com/EventedMind/iron-router",
      "branch": "dev"
    },
    "dimsum": {},
    "iron-router-progress": {}
  }
}

and run mrt update again. Works fine now.
