Why does this problem not work in VS code?

Question

Why is my problem not working? I'm pretty sure about regex, but it doesn't report any problems, even some of them 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'.

I solved the problem by placing tasks.json in the .vscode folder. Initially, I thought tasks.json would be found as tsconfig.json (project-root), but it turned out to be wrong.
