Compile fails on symlink

[econeale]

Describe the problem

When executing arduino-cli compile within a project that is also a git repository, I receive this error:

/Users/neale/myProject/.git/hooks/pre-commit: no such file or directory

This pre-commit hook is a symlink to a shell script that's also contained in the repository. This appears to happen regardless of where the symlink points / exists in the repository. There appears to be no way to work around the error other than completely removing the link.

To reproduce

Create a project with the structure:

• myProject
  • myProject.ino
  • aLink -> /somewhere/else

Execute arduino-cli compile within the directory.

Expected behavior

Several solutions to this come to mind:

1. Recursing hidden directories probably shouldn't happen by default
2. Ability to explicitly list files / directories to compile
3. An option to follow / not follow symlinks

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the nightly build
• My report contains all necessary details

Hm, I recall that .git (or maybe all hidden directories) were already filtered out from the list of files to compile/load, but maybe I remember wrong (or this was changed at some point, maybe).

In any case, I ran into issues with (broken) symlinks breaking compilation before, see #1438 for an attempt at fixing this (which is probably not ideal, but will be useful as a starting point and see some of the previous attempts, considerations and involved code).

This requires two fix IMHO:

1. ignore .git folders in sketches
2. ignore broken symbolic links and continue the compilation anyway.
