Linter sometimes fails to report issues on a specific PC

So for example
1. I create a few commits, push a PR
2. Build is executed on TeamCity, check task fails
3. Same task on my PC somehow ignores these errors
https://github.com/Kotlin/dataframe/pull/858
clean doesn't seem to do anything too

Start by comparing the linter task on the reporter's PC with the TeamCity build described in PR #858, including whether the clean task actually removes prior state. Reproduce the differing results and identify why local execution omits errors that TeamCity reports. Done means the same lint issues are reported consistently in both environments.
