Calling variable from jason

Initially i read data from xml file and stored in varible xml, later i converted into jason format and saved it in variable json. Following is the data saved in variable Jason in json format.

{ 'maven2-moduleset':
       { '$': { plugin: 'maven-plugin@2.15.1' },
         actions: [ '' ],
         description: [ '' ],
         keepDependencies: [ 'false' ],
         properties: [ [Object] ],
         scm: [ [Object] ]}}

when I'm trying too access

console.log(jason.maven2-moduleset.$.scm)

it's throwing following error

events.js:154
      throw er; // Unhandled 'error' event
      ^

I want to get data in 'scm' , Don't know where I'm doing wrong. Could tell me how to display data in scm object.
