Random ClassNotFoundError PhpStanExtractor.php line 67

[fliespl]

A few times a day, I am getting following exception in symfony project. Clearing symfony cache fixes it - any ideas what could be the issue since it's random?

Uncaught Error: Class "PHPStan\PhpDocParser\Parser\PhpDocParser" not found

Uncaught PHP Exception Symfony\Component\ErrorHandler\Error\ClassNotFoundError: "Attempted to load class "PhpDocParser" from namespace "PHPStan\PhpDocParser\Parser". Did you forget a "use" statement for another namespace?" at /home/flies/workspace/sf5/homologacja/vendor/symfony/property-info/Extractor/PhpStanExtractor.php line 67

Please tell us more. What are you running when you get this exception? Is phpstan/phpdoc-parser dependency of your own project?

Using phpstorm with inspections enabled. After doing some code changes and going back to browser I get this error:

Same here.

I am testing right now with adding phpstan/phpdoc-parser as direct dev requirement - seems promising for now.

Same issue here, this workaround also works for me.
