My config

{
  "includes": [
    "app"
  ],
  "exclude": [
    "tests",
    "vendor",
    "docker"
  ],
  "report": {
    "html": "./tmp/php-metrics/report/",
    "csv": "./tmp/php-metrics/report.csv",
    "json": "./tmp/php-metrics/report.json",
    "violations": "./tmp/php-metrics/violations.xml"
  }
}

"docker" folder has access restrictions and added to config exclude. Despite this, the script tries to scan this folder.

If you run the script from another folder, for example from vendor, then there is no such problem. It looks like at startup there is a search for something without checking permission.

Couldn't reproduce. It scans inside includes folder and excludes all the directories in array. Doesn't matter from where phpmetrics in run, as long as relative path to .phpmetrics.json is provided.
