[MNG-8056] Parameter '-f' & '-s' fails with absolute paths on Cygwin

**[Oliver Glowa](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=ollily)** opened **[MNG-8056](https://issues.apache.org/jira/browse/MNG-8056?redirect=false)** and commented

Hello,

I'm using shell-script's running on github actions. For testing purpose I test the scripts locally on windows with cygwin. When working with absolute paths the parameter '-f', '-s' are failing on cygwin.

Similar problem like MNG-7621, but I don't see a chance to solve this as easy in the shell script, too. How do you will identify the path(s) from the commandline an replace it with a proper version.

## Tested with

* Windows 10x64 / 11x64
* Cygwin 3.5.0-1.x86_64
* Maven 3.9.6

1. Extract attachment "parametertest.zip to /cygdrive/c/temp
2. switch to /cygdrive/c/temp

## Log for "-f" with relative path

**Affects:** 3.9.6

**Attachments:**

**Issue Links:**
- [MNG-5812](https://issues.apache.org/jira/browse/MNG-5812) Project base dir not fully working in Cygwin

- [MNG-7621](https://issues.apache.org/jira/browse/MNG-7621) Parameter '-f' causes ignoring any 'maven.config' (only on Windows)

Reproduce the reported `mvn -f` and `mvn -s` commands under Cygwin using the attached parametertest.zip, comparing relative and absolute paths. Start by tracing Maven's command-line handling for `-f` and `-s`, then review MNG-5812 and MNG-7621 for related behavior. Done means absolute Cygwin paths resolve correctly for both options without breaking Windows paths.
