For Scrutinizer something similar should be adopted:

It could also be set with a commit configuration file, if you prefer.

I think this would be better: I don't have control on the Scrutinizer account at the moment

Thanks a lot for the help!

[Slamdunk]

Done. Scrutinizer triggers seem stalled, but the build passed the stage this PR aims to.

Hm maybe it needs the complete config. Prior to your changes it was:

filter:
    excluded_paths: [vendor/*, app/*, web/*]
    
before_commands:
    - "composer install"

tools:
    php_cpd: true
    php_pdepend:
        excluded_dirs: [vendor]
    php_loc: true
    php_mess_detector: true
    php_analyzer: true
    php_code_coverage: true

I've messed up and can't figure out why the variable is not taken into account anymore 😃

[theofidry]

maybe we can just export it manually in the before_commands?

[Slamdunk]

Mmm 😕

[Slamdunk]

Ok, the first version of the configuration was good, PR ready to merge

Thanks very much!
