git branch error: unknown option show-current

[alrf]

Pipeline fails with:

Run dorny/paths-filter@v2.10.1
Get current git ref
  /usr/bin/git branch --show-current
  error: unknown option `show-current'

paths-filter/src/git.ts

Line 168 in 78ab00f

const branch = (await exec('git', ['branch', '--show-current'])).stdout.trim()

git version 2.20.1 is used.

The same issue as for actions/checkout: actions/checkout#121

We get a similar issue:

Get current git ref
/usr/bin/git branch --show-current
fatal: not a git repository (or any of the parent directories): .git
Error: The process '/usr/bin/git' failed with exit code 128

@alrf: Thanks for reporting the issue. I will use the same workaround as they used in the checkout action.

@balazsorban44: The error you get is not related to this issue. You are using paths-filter in a workflow triggered by push event. In this case, you have to use the checkout@v2 step before paths-filter. Without checkout it works only for workflows triggered by a pull request event.

We're seeing the same show-current error on certain buster and centos images using checkout@v3
