Thanks @kelemen for the PR. Could you update the user guide and sample (as an example, see the Working with Files section of the user guide)? Thanks!

I have updated the user guide and also merged master for convenience.

Thanks @kelemen for your contribution. I cherry picked your changes and did minor typos changes. I merged your changes into master so I will close the PR.

@kelemen Would you be interested in an additional contribution and looking into improving Gradle's handling of NIO Path in general? Have a look at issue #1205. Zero pressure on you to address this, but, if you want, we can discuss on the issue.
