title: pass the arguments in a json file
body: <p>I need to pass the branch name in git-dependencies as a parameter. But in my <code>packages.json</code>, I am unable to do so. The structure looks something like following:</p>
  
  <pre><code>{
      "servers" : [
              ...
               ],
      "target" : "apps",
      "git" : {
              "git-remote" : "..."
          },
      "source" : {
              "git-dependencies-path": "../",
              "source-packages-path" : "../"
             },
      "wiki" : {
              "local-wiki-path" : "../",
              "git-wiki-path" : ""
           },
          "git-dependencies" : [  {"repository" : "application/app1", "branch" : "development", "source-packages" : [ "."]}, //the branch name I want to parameterize}],
     }
  </code></pre>
