Thanks for reporting @palakaccorin. I cannot reproduce with current information.

Can you provide some additional info?

• You can run grumphp with the -vvv flag. This will give you the command that is being executed. (maybe best to create a grumphp file with only phpmd). You can manually run this command to see what the status code and output of this command is.
• What version of php, phpmd, ... are you using?
• Do you always get this error - or only in specific scenarios
• ...

Would it be possible to provide a repository that produces the isolated issue without the other tasks?
