Why doesn't this problemMatcher in VS code wor

问题:

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

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.
