title: gulp.dest does not print to file
body: <p>Hello I am having issues with gulp. Code bellow does not create anything in dist/ folder</p>
  
  <pre><code>function compileSources() {
      return gulp.src([ './src/**/*.js' ], {
          read: false
      })
      .pipe(debug())
    /*.pipe(concat('all.js'))
      .pipe(debug())*/
      .pipe(gulp.dest('./dist/'));
  } 
  gulp.task('compile-sources', compileSources);
  </code></pre>
  
  <p>Debug outputs </p>
  
  <pre><code>[10:56:45] Using gulpfile ~/otb-web-app/gulpfile.js
  [10:56:45] Starting 'compile-sources'...
  [10:56:45] gulp-debug: src/app.js
  [10:56:45] gulp-debug: 1 item
  [10:56:45] Finished 'compile-sources' after 28 ms
  </code></pre>
  
  <p>But in /dist folder nothing is created. Why could that be? </p>
