How to get rid of Checkstyle message ‘File does not end with a newline.’

In my case that was a problem with improper configuration of that checker. By default it uses system default convention of line endings. I was working on windows and the project was using unix-style line endings. I don’t think ignoring the warning is the best strategy, so what I’ve done is:

<module name="Checker">
    <module name="NewlineAtEndOfFile">
        <property name="lineSeparator" value="lf" />
    </module>
</module>
