[Docs] watch task without completion signal

[valtlai]

The sample code in README contain the following Gulp task, which doesn’t signal async completion.

function watch() {
  gulp.watch(paths.scripts.src, scripts);
  gulp.watch(paths.styles.src, styles);
}

When I run a very similar task, the console says:

[23:01:10] The following tasks did not complete: watch
[23:01:10] Did you forget to signal async completion?

Should the example code be updated or did I miss something?

Why is your watch task ending? Watch tasks are meant to run forever until ctrl+c is used to end it which exits the program outside of that logging.

I don’t know. Most of the time the task working perfectly but sometimes it just ends. Very hard to reproduce.

But yeah, you’re right and the docs don’t need updating.

Maybe it’s gulpjs/glob-watcher#55 causing this issue. I’m using Node 14.

my gulp watch did not completing the task too

gulp.task('x', function (done) {
  console.log('x');
  done();
});
gulp.task('watch', function () {
  gulp.watch('./posts/**/*.md', { delay: 1000 }, gulp.series(['x']));
  setTimeout(() => {
    fs.appendFileSync(__dirname + '/posts\\hexo-theme-unit-test\\post-watcher.md', EOL);
  }, 1000);
});

i've been finding from google, but the answer is same. and i try to test, but not working. iam using "gulp": "^4.0.2"
