> FileUtils.deleteDirectory can throw UncheckedIOException
> --------------------------------------------------------
>
> Key: IO-814
> URL: https://issues.apache.org/jira/browse/IO-814
> Project: Commons IO
> Issue Type: Bug
> Affects Versions: 2.13.0, 2.14.0
> Reporter: Elliotte Rusty Harold
> Priority: Critical
>
> This was a behavior breaking change, and an incorrect one to boot.
> Operations that can have I/O errors should throw IOException if they can't
> directly handle the I/O error. UncheckedIOException is not a reasonable
> alternative.
> A method that can neither handle nor throw IOException must not perform I/O
> operations.
> It's worth noting that functional programming, not just in Java but in
> general, does not allow I/O. As soon as a method performs I/O, it's no longer
> a pure function and should not be written in a functional style.
