Why doesn't this problemMatcher in VS code work?

Question

Why doesnt my problemMatcher work? I'm pretty sure about the regex, but it doesn't report any problems, even there are some on stdout...

// the matcher
"problemMatcher": {
    "owner": "typescript",
    "fileLocation": ["relative", "${workspaceRoot}"],
    "pattern": {
        "regexp": "^TypeScript (warning|error): (.*)\\((\\d+),(\\d+)\\): (.*)$",
        "severity": 1,
        "file": 2,
        "line": 3,
        "column": 4,
        "message": 5
    }
}

//the browserify/tsify pipeline
browserify().add('main.ts')
  .plugin(tsify, { noImplicitAny: false, removeComments:true })
  .transform("babelify",{ extensions: ['.ts'], presets: ["es2015"]})
  .bundle()
  .on('error', function (error) { console.log(error.toString()); })
  .pipe(source('bundle.js'))
  .pipe(gulp.dest('www/js/dist/'));

//gulp sample output
[00:39:00] Starting 'ts-compile'...
TypeScript error: main.ts(118,30): Error TS2339: Property 'object' does not exist on type 'boolean'.
TypeScript error: main.ts(137,24): Error TS2339: Property 'object' does not exist on type 'boolean'.
TypeScript error: main.ts(507,44): Error TS2304: Cannot find name 'loading'.
[00:39:03] Finished 'ts-compile' after 2.98 s

All regex libraries seem to differ in their details. If the regex is at fault, I'd suspect that the alternation operator `|` has higher precedence than expected. Try `((warning)|(error))` and see if that changes anything. — eh9, Dec 09 '15 at 11:06
@santa The regex works indeed. I'm able to get hree errors for the sample output in VSCode using your problem matcher. How does your tasks.json file look like? — Wosi, Dec 09 '15 at 16:21
already found my problem @Wosi i had to put the tasks.json into the .vscode folder (which contained a default which made me think that mine was used in the first place) — santa, Dec 09 '15 at 17:37

I resolved the problem by putting tasks.json into .vscode folder. I initially thought tasks.json would be found like tsconfig.json (project-root), but it turned out to be wrong.
