scanDirectories config seems to influence ResultCache

[staabm]

Bug report

in our CI pipeline the result cache usually works.

I can see that result cache is not used in a particular project with a pretty simple config

includes:
    - phpstan-baseline.neon

parameters:
    resultCachePath: %tmpDir%/resultCache-motion-scripts.php
    level: 7
    paths:
        - .
    bootstrapFiles:
        - phpstan-bootstrap.php
        - phpstan-dba-bootstrap.php
    scanDirectories:
        - ../lib/
    excludePaths:
        analyseAndScan:
            # ignore files which executed code when beeing included, instead of only defining logic
            - */config/*

    ignoreErrors:
         - '#Class shop referenced with incorrect case.*#'
         - '#Call to an undefined method shop.*#'

the only thing which stands out is the use of scanDirectories... on the CI console I can see

Result cache not used because the metadata do not match: projectConfig, scannedFiles

I will leave this issue here for bugtracking and to get a issue number :-).
I will update the issue as soon as I know more - stay tuned.

Code snippet that reproduces the problem

No response

Expected output

result cache should be used and not work differently when scanDirectories is used

Did PHPStan help you today? Did it make you happy in any way?

No response

You can figure out what's different by diffing resultCache-motion-scripts.php before the run and after the run.

thanks, thats a great advice which helped to narrow the problem.

in our case the problem is/was, that because of a bug in the github actions workflow, a very old result-cache was restored in some cases, which in turn made PHPStan reporting, that the scannedFiles are no longer up 2 date.
