doesn't exclude ./vendor

[Volker89]

I'm running Assumptions with the following command on windows 10:

tool-assumptions --exclude=./vendor ./

And i get this error:

PHP Fatal error: Uncaught PhpParser\Error: Syntax error, unexpected '{', expecting T_STRING on line 2 in C:\Users\vheidemann\projects\ci-tool-installer\assumptions\vendor\nikic\php-parser\lib\PhpParser\ParserAbstract.php:293

Any ideas what to do?
