Anti-Grief plugin which prevents users to break blocks you want.
It's really simple and lightweight.

You only have to download and put this plugin into plugins folder of your server.
Then go to config.yml and insert IDs of blocks you want to disable break
Now start the server!

Here you can disable metrics for this plugin by setting opt-out to true and can also set up which blocks cannot be broken by players.
For a full list of IDs use this image as a reference: Data Values

New options in v0.2

If you want to block all blocks just set block-all to true and reload config.
You can customize the message that is sent to player, who don't have permission, when he try to break blocked blocks or you can even disable this message.

NOTE: If you want to remove all blocked-materials, set your config as following:

blocked-materials: []

It should work! (thanks to @Bigtcsyle for bug report about this).

Instead of /antiblockbreaker you can use /abb as an alias.

Added in AntiBlockBreaker 0.2
