TypeScript compiler does not transpile modules to javascript

Question

I have imported five libraries in my .ts file as below. When I compile the file using TS 1.8 compiler it only add three imports to .js file resulting undefined VssService and ExtensionDataService. Does anyone know how to resolve this?

Imports in .ts file

import VssService = require('VSS/Service');
import ExtensionDataService = require('VSS/SDK/Services/ExtensionData');
import tl = require('vsts-task-lib/task');
import url = require('url');
import path = require('path');

Compiled .js

var tl = require('vsts-task-lib/task');
var url = require('url');
var path = require('path');

Thanks-

404, can you update the link?

First, make sure you add VSS.d.ts reference.

Secondly, based on my test, it won’t generate related code if the variable not be used. I added console.log(VssService) and console.log(ExtensionDataService), then these code is generated.
