ESLint Cache

Hi!

I've recently setup ESLint for my project, and I've noticed periodic performance drops with it (not related to IDE itself). I wanted to enable caching, so added respective command-line parameters to settings in PHPStorm:

--cache --cache-location="/js/.eslintcache/" --cache-strategy=content

But it does not look like they are being used, since the neither a folder nor a file (if I remove the trailing slash) is created anywhere on my PC. I also tried using spaces instead of equal signs, and dropping `--`, but no luck. Is it possible to setup PHPStorm to use cache for ESLInt?
