Trying to run grumphp with php 8.1 trhow some deprecation errors:

Steps to reproduce:
To reproduce use a docker version with php 8.1-rc5 for example:

Result:

root@e7d1fc12dea6:/application# ./vendor/bin/grumphp run

Deprecated: strlen(): Passing null to parameter #1 ($string) of type string is deprecated in /application/vendor/symfony/filesystem/Filesystem.php on line 114

Deprecated: file_exists(): Passing null to parameter #1 ($filename) of type string is deprecated in /application/vendor/symfony/filesystem/Filesystem.php on line 118

Deprecated: GrumPHP\IO\ConsoleIO implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary) in /application/vendor/phpro/grumphp/src/IO/ConsoleIO.php on line 17

Thanks for pointing it out.
The first 2 are related to Symfony packages. What package versions are you using?

The last one is indeed an internal issue. Care to create a PR?

We are planning to support both php 8.1 and Symfony 6 at the end of the month, shortly after their release.

I'm not using symfony on this project, it might be used by another tool...

I'll see if I can dd a PR before the end of the week

We are using Symfony components internally for GrumPHP. But the installed versions may very based on your setup.
You can check the versions by running composer show
