ReflectionException：升级 Symfony 后类不存在

Question

After upgrading my php version from 5.6 to 7.3 and upgrading Symfony from 3.4 to 4.4 I get an ReflectionException everytime I try to access my application on my localhost.

    ReflectionException:
    Class WaiverBundle\File does not exist

I have not made any changes in the used files and WaiverBundle\\File still exists in the directory "WaiverBundle\\Entity\\File". I have also deleted the cache and restarted the web server, but still receive the error message. I suspect that it could have something to do with the VichUploaderBundle I use, but I did not make any changes to that in the uprading process.

Does anyone have an idea how to get rid of this error?

Answer 1

You've answered your own question.

[…] WaiverBundle\\File still exists in the directory "WaiverBundle\\Entity\\File".

Those are not the same thing, from the trace it looks like you have an annotation referring to WaiverBundle\\File instead of WaiverBundle\\Entity\\File .
