Add the exclude option to the phpcs-task: https://github.com/squizlabs/PHP_CodeSniffer/wiki/Advanced-Usage#limiting-results-to-specific-sniffs

You need to update spec/Task/PhpcsSpec.php by add

$options->getDefinedOptions()->shouldContain('exclude');

after this line https://github.com/phpro/grumphp/blob/master/spec/Task/PhpcsSpec.php#L54

Hmm, tests are failing because of the following error:
1) GrumPHPTest\E2E\FolderStructuresTest::it_has_all_config_files_in_root_git_dir 320Symfony\Component\Process\Exception\ProcessTimedOutException: The process "c:\tools\php71\php.EXE C:\tools\composer install --optimize-autoloader --no-interaction" exceeded the timeout of 60 seconds.
