Magento2.Annotation.MethodArguments.MethodArguments can't deal with phpstan-style array argument types

[hostep]

Preconditions

This started happening after upgrading the coding-standard library from version 6 to version 10 on a custom module of mine.

I suspect that this library currently can't deal wit phpstan-style array argument types (and psalm has the same concept btw)

Steps to reproduce

1. Have a class like this:

<?php

declare(strict_types=1);

namespace Whatever;

use Symfony\Component\Console\Output\OutputInterface;

class SomeClass
{
    /**
     * @param array<array<string, mixed>> $categoryData
     */
    public function outputResult(array $categoryData, OutputInterface $output): int
    {
        return 0;
    }
}

2. Run this library over it

Expected result

1. No warnings

Actual result

1. Warnings:

--------------------------------------------------------------------------------------------------------------------------------------
FOUND 0 ERRORS AND 2 WARNINGS AFFECTING 1 LINE
--------------------------------------------------------------------------------------------------------------------------------------
 14 | WARNING | @param is not found for one or more params in method annotation

Just ran into the same issue. Would love to see this fixed. For now, I disabled the magento-coding-standard checks in our CI pipeline in favor of phpstan.

Although this is not how it should be, and this issue should be addressed correctly, you might skip the error detection by removing any space within the parameter's type section:

    /**
     * @param array<array<string,mixed>> $categoryData
     */
