Prework

• [x ] Read and agree to the code of conduct and contributing guidelines.
• [ x] Confirm that your issue is a genuine bug in the targets package itself and not a user error, known limitation, or issue from another package that targets depends on. For example, if you get errors running tar_make_clustermq(), try isolating the problem in a reproducible example that runs clustermq and not targets. And for miscellaneous troubleshooting, please post to discussions instead of issues.
• [ x] If there is already a relevant issue, whether open or closed, comment on the existing thread instead of posting a new issue.
• Using targets::tar_reprex(), reprex::reprex(), or similar, post a minimal reproducible example like this one so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • Readable: format your code according to the tidyverse style guide.

Description

In trying to use the workflow created by tar_github_actions(), I'm running into the following error:

Run git config --local user.name "GitHub Actions"
  git config --local user.name "GitHub Actions"
  git config --local user.email "[email protected]"
  rm -r .gitignore .github/workflows
  git add --all -- ':!renv'
  for file in $(git ls-files -mo --exclude=renv)
  do
    git add $file
  done
  git commit -am "Run pipeline"
  git push origin targets-runs
  shell: sh -e {0}
  env:
    GITHUB_PAT: ***
    RENV_PATHS_ROOT: ~/.local/share/renv
    INCITES_KEY: ***
    LANG: en_US.UTF-[8](https://github.com/tarensanders/cv/runs/5746071805?check_suite_focus=true#step:13:8)
The following paths are ignored by one of your .gitignore files:
_targets/meta/process
Use -f if you really want to add them.
Error: Process completed with exit code 1.

In lieu of a reprex, I forked the targets-minimal repo (fork is here). The workflow ran fine the first time. But once I removed the existing targets-runs branch (i.e., to make it the same as a new project), the workflow fails with the same error I am getting. You can see the failed workflow here.

I think the issue is that one or more of the files trying to be committed is listed in the .gitignore within the _targets folder. Changing the line git add $file to git add $file -f (as suggested by the error message) fixes the issue, but I don't know enough about git to know if that's a reasonable solution.

EDIT: Just noting that I don't think git add $file -f is the right solution. It commits the meta/process and meta/progress files everytime, which seems excessive. Maybe additional files need to be passed to exclude?
