Running plugin-ci under php 8.x shows multiple deprecation warnings

[kiklop74]

When executing any moodle-plugin-ci command under PHP 8.x numerous deprecation warinings are being issued.

PHP Deprecated:  Return type of Symfony\Component\Finder\Finder::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /opt/moodle-plugin-ci/vendor/symfony/finder/Finder.php on line 566
PHP Deprecated:  Return type of Symfony\Component\Finder\Finder::count() should either be compatible with Countable::count(): int, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /opt/moodle-plugin-ci/vendor/symfony/finder/Finder.php on line 637
PHP Deprecated:  Return type of Symfony\Component\Finder\Iterator\FilterIterator::rewind() should either be compatible with FilterIterator::rewind(): void, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /opt/moodle-plugin-ci/vendor/symfony/finder/Iterator/FilterIterator.php on line 32
PHP Deprecated:  Return type of Symfony\Component\Finder\Iterator\FileTypeFilterIterator::accept() should either be compatible with FilterIterator::accept(): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /opt/moodle-plugin-ci/vendor/symfony/finder/Iterator/FileTypeFilterIterator.php on line 42

This is because project uses older symfony/console version. It needs to be upgraded to at least v6.0.7 that fixes this issue.

These are the steps that need to be executed to update composer.json and lock the version on master branch

cd <ci dir>
composer config platform.php 8.0.2
composer require -W 'symfony/console:^v6.0.7' 'sebastian/phpcpd:^v6.0' 'stecman/symfony-console-completion:^0.12'

Note that we are really, really near releasing version 4.0 (from master branch). It uses Symfony 5.x and will support all Moodle branches >= 38_STABLE and PHP >= 7.4.

You can sneak preview it by changing the ^3 version by dev-master (soon to become ^4).

The plan & progress is being tracked @ #151 .

Ciao :-)

OK, that is great news. Closing this one.
