Exclude folders

[otaviosoato]

Hi folks,

I don't know if I'm doing something wrong, but I can't exclude folder from cache using "!" before the path.

- uses: actions/cache@v2.1.4
  with:
    path: |
      Library/
      !Library/Artifacts/ 

The snippet above should work, right?

PS: English is not my native language. Sorry if I wrote something wrong.

Thank you!

Yes, this action internally uses the glob package of the actions toolkit, and it should support that.

Glob does support exclusions but unfortunately because the cache just matches the top-level folders and does not traverse any descendants, exclusions on nested folders don't work. actions/toolkit#713 has more details.

Thanks @dhadka ! I'm got crazy trying to make that work. But I can rest in peace now haha
