Good job. However, could you please add the copyright annotations?

@serhiyzhovnir could you please fix the failing static tests?
Thanks.

Hi @eduard13 @VitaliyBoyko
I fixed all errors with static tests and also I had added the excluding for the category/java/documentation.xml/CommentSize rule. This rule throws the error if a method docs comment has more then 6 lines, it's a problem for methods with many arguments.
For this PR it throws the error on this method comment: https://github.com/magento/magento2-phpstorm-plugin/pull/238/files#diff-dc18067fb134408559fa7f2888c01ad8R63-R73.
Could you review this one, please?
Thank you!
