Why is Visual Studio Code ignoring my tasks.json file?
<p>I have a problem with tasks.json, which I have simplified by reducing it to the following.</p>

<p>At the root of my Visual Studio Code project, clearly visible inside of the file explorer sidebar as a root folder is .vscode, and inside of .vscode is tasks.json. This was auto-generated for my by VSCode and I did not move the folder or the project or point VSCode to a different folder.</p>

<p>The contents of tasks.json is as follows:</p>

<pre><code>{
    "version": "0.1.0",

    // The command is tsc. Assumes that tsc has been installed using npm install -g typescript
    "command": "tsc",

    // The command is a shell script
    "isShellCommand": true,

    // Show the output window only if unrecognized errors occur.
    "showOutput": "silent",

    // args is the HelloWorld program to compile.
    "args": ["test.ts"],

    // use the standard tsc problem matcher to find compile problems
    // in the output.
    "problemMatcher": "$tsc"
}
</code></pre>

<p>Please note that the original default value of "args" was ["HelloWorld.ts"], however I have simply changed it to ["test.ts"].</p>

<p>Now, when I press ctrl-shift-b, I get the following:</p>

<blockquote>
  <p>error TS6053: File 'HelloWorld.ts' not found.</p>
</blockquote>

<p>Note that I do clear the output in the output window every time I attempt this. It looks like VSCode is ignoring my tasks.json file and is using default settings.</p>

<p>I am on Ubuntu 14.04.</p>
