How to create a shrinking world border in Minecraft

Question

I'm trying to create a shrinking world border in Minecraft with a Bukkit plugin. Im trying to do it with a scheduler so it shrinks every second 1 or 2 blocks.

Help is appreciated!

You can use the World Border.setSize(double, long) method.
