Gulp watch tasks fails on temporary files created by IDE

[jodator]

I have some problems with gulp build --watch when using it inside IDE (PHPStorm).

The problem is that probably PHPStorm creates temporary file when saving source file.
Example error:

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: ENOENT: no such file or directory, stat '/home/jodator/projects/cksource/ckeditor5/git/ckeditor5-engine/src/treemodel/delta/insertdelta.js___jb_tmp___'
    at Error (native)

To address this we could specify patterns of files to watch only for those that matters (js, jsdoc, html, scss, etc) but this might be cubersome. Also we could exclude jb_tmp as this is probably used by JetBrains products.

We can't whitelist files that must be included, so we must blacklist them. We simply won't be able to predict all kinds of files which need to be copied by the builder.

I had similar problem with WebStorm - I've disabled Use "safe write" (save changes to a temporary file first) in Apperance & Behavior -> System Settings. It's not the best solution but it's working for me for a while without any problems.
