cache doesn't work with github workspace directory

[erwan-joly]

Hi, I'm trying to cache the whole workspace to fetch it between jobs.
Unfortunately it seems like the local directory can not be cached

Using . doesn't work (it cache 22B)

- name: Cache build folder
        uses: actions/cache@v3
        with:
          key: cs-repo-${{ github.run_number }}-${{ github.run_attempt }}
          path: .

Using ${{ github.workspace }} doesn't work (it also cache 22B)

- name: Cache build folder
        uses: actions/cache@v3
        with:
          key: cs-repo-${{ github.run_number }}-${{ github.run_attempt }}
          path: ${{ github.workspace }}

the only solution I found which work is to list all the files/directory

- name: Cache build folder
        uses: actions/cache@v3
        with:
          key: cs-repo-${{ github.run_number }}-${{ github.run_attempt }}
          path: |
              file1
              file2
              dir1
              dir2

Thank you for the report. I was able to reproduce this. From the first look, it appears that there is a bug while converting the cache paths to relative paths for compression in the toolkit. I will debug the cause and get back.

Contribution are welcome as this will mostly require changes in actions/toolkit and actions/cache.

It doesn't seems to be fixed for some reason :/
I've tested with actions/cache@v3.0.1 both the two version with . and env variable and it still cache 22B @pdotl

Hi @erwan-joly , the above version is for actions/cache npm module and not for the actions/cache action. We are yet to merge toolkit changes into the actions/cache. Once done, you should be able to test and use the same. I'll post an update here once done.

@erwan-joly ,please test now with the latest version of actions/cache using actions/cache@v3.

@pdotl I confirm it's now fixed 💯
