# Re: 'mvn verify' fails on rat plugin

These files are automatically detected as binary files on unix and thus automatically ignored by the RAT plugin, but not on Windows. Most Flink devs run unix and don't run into this problem, and thus don't define a proper exclusion.
```This happens regularly.

It would be great if you could open a PR to add the missing exclusions.
