      "type": "process",
      "problemMatcher": {
        "owner": "php",
        "fileLocation": ["relative", "${workspaceFolder}"],
        "severity": "warning",
        "pattern": {
          "regexp": "^(ERROR):\\s([^\\s]+)\\s-\\s([^:]+):([0-9]+):([0-9]+)\\s-\\s(.+)$",
          "file": 3,
          "line": 4,
          "column": 5,
          "severity": 1,
          "message": 6,
          "code": 2
        }
      },
      "command": "vendor/bin/psalm",
      "args": [
        "${file}"
      ],
      "presentation": {
