GriefPrevention - Minecraft anti-griefing plugin

Stop responding to grief and prevent it instead. Grief Prevention will solve your grief problems without a roster of trained administrators, without 10 different anti-grief plugins, and without disabling any standard game features. Because Grief Prevention teaches players for you, you won't have to publish a training manual or tutorial for players, or add explanatory signs to your world.

Grief Prevention stops grief before it starts automatically without any effort from administrators, and with very little (self service) effort from players. Solve all your grief problems with a single anti grief download, no database, and (for most servers) no configuration customization.

Features list

• No database or world backups required.

• Extremely efficient CPU / RAM usage.

• Land claims are easy to manage.

  • Players create and manage their own land claims, so you don't have to do it for them.
  • New players get automatic claims around their first chests so they're protected even if they don't know how to create land claims yet.
  • Players who ask for help in chat get an instant link to a demonstration video.
  • Resizing claims and creating new claims is done with ONLY the mouse, no slash commands (slash commands are also available).
  • When a player appears to be building something nice outside his claim, he's warned and shown his claim boundaries.
  • Claim boundaries are easy to see, and don't require any client-side mod installation.
  • Extremely easy-to-remember, single-parameter slash commands for giving other players permissions.
  • Claim subdivision and granular permissions are available to organize towns and cities. Watch this video.

    • Insanely easy and fast fixes for penises, swastikas, and anything else unsightly.
    • Point at what you don't like and click, and it's fixed. Even from far away.
    • Never accidentally changes blocks inside land claims.
    • No need to investigate who built it, who broke it, or when they did it.
    • Doesn't matter if the griefer built with "natural" blocks, it will still be fixed.
    • No database.
    • No backups.
    • No chunk regeneration (it's dangerous for technical reasons).
    • Fixes bad chunk generations, like floating islands. It will be better than new.
    • Fills holes, even next to water to correct big spills.
    • Smooths noisy terrain.
    • No griefer construction is safe. If it's unnatural enough to be noticeable by players, it will be removed or filled-in.

• Land claims can't be used as a griefing tool.

  • It's impossible to get a player "stuck" inside a land claim.
  • Land claims beyond the first require a golden shovel.
  • Minimum claim size prevents sprinkling small claims to annoy other players.

Adding GriefPrevention as a maven/gradle/etc. dependency

GriefPrevention will be added to maven central soon - in the meantime, there's this neat thing called JitPack that makes a public maven repo for public Github repos on the fly. According to it, this is all you need to do to add to your pom.xml:

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Replace <version> number with this number:

	<dependency>
	    <groupId>com.github.TechFortress</groupId>
	    <artifactId>GriefPrevention</artifactId>
	    <version>16.7.1</version>
	</dependency>

You can also add it to gradle/sbt/leiningen projects: https://jitpack.io/#TechFortress/GriefPrevention/
