Exception is thrown in case target directory doesn't exist

[samdark]

Searching files to process... Exception 'yii\base\InvalidParamException' with message 'The dir argument must be a directory: /Users/samdark/src/yiiframework.com/data/yii-2.0/docs/guide'

Instead of throwing an exception it can create a directory.

how did you call it? it is supposed to create that dir already automatically. at least for me this works fine.

Confirmed that it's completely my issue. Sources weren't there yet.
