Handling gulp.watch errors in Gulp 4

[demisx]

I have this task watching various code paths in G4:

gulp.task('watch:code', function () {
  gulp.watch([
    paths.html,
    paths.js,
    paths.images,
    paths.json,
    paths.vendor.bower.js,
    paths.vendor.bower.css,
  ], gulp.series('build', browserSync.reload));
});

Each time I move files around in one of those directories gulp.watch crashes with this error:

Error: ENOENT, no such file or directory '/Users/dmoore/projects/dimaslist/dimaslist-org-desktop/app/components/_mocks/untitled folder/'
  at Object.fs.readdirSync (fs.js:665:18)

Can you guys please point me in the right direction on what would be the proper way to handle gulp.watch errors in Gulp 4? Basically, I just want to write the error to the console without gulp.watch crashing each time. Thank you.

@demisx I think this will be debated more in #359. You should just close this because it's pretty much a dupe and subscribe to that issue.

[demisx]

@ilanbiala Sure, but my only concern is that #359 hasn't been updated since August 26 and gulp.watch crash affects us every day. I am wondering maybe the core guys can suggest a way or a workaround we could use now until the official documentation is ready.

It's better to ask about it there, where others will get notified about it.

This is a bug in gaze, the library responsible for file watching. I understand that bugs in that library are a pain in the ass but I have never touched that code base before and we're at the mercy of that author to fix these bugs. See #651 where all watch bugs are being pooled for now. Supposedly a new version of gaze is coming out that will solve these, but it has been months and no progress.

@contra Thank you for clarification. I'll bug the gaze now.
