Description

This utility library shares all the common code needs for various plugins, and having them in one library heavily reduces the amount of duplicated code. The featured utilities are varied, and whenever something is missing in Bukkit, it is added in BKCommonLib. This is one of the reasons why it has become this large: there are simply a lot of things Bukkit doesn't (want to) offer.

BKCommonLib has versioning on a per-plugin basis, so when a certain plugin needs version 2, and version 1 is installed, the server owner is automatically notified and the plugin is not enabled. This prevents the common mishaps with outdated BKCommonLib versions.

Other than utilities and services, this library offers a wide variety of reflection and user-friendly ways of accessing net.minecraft.server. If your plugin requires the use of the internals, but do not want to risk changing field and method names, you can depend on BKCommonLib to provide them for you. This allows you to remain compatible between CraftBukkit versions automatically, and reduces silent failure hazards.

Reasons for you to depend on this library

You need to access Minecraft internals in your plugin, and Bukkit has no API for it
You are tired of re-uploading the same version over again because of the internals changing
You want to work with Vector/math logic, or need to use other utility classes
The YAML of Bukkit dislikes you, and you want this to be easier
You want to easily read and write configuration/data files
You want easy access to data conversion utilities to convert user input
You want to work with inventories in an advanced fashion
You want to work with unique server events
You want to alter entity behaviour (such as handling block collisions, custom movement, etc.)
You want plugin messages/permissions to be configurable
You want to work with (async)tasks without storing IDs
You want to send and manipulate packets

Getting started

To start using BKCommonLib, you have two options (after adding BKCommonLib as dependency in the plugin.yml):

Include the jar file as a dependency

Like any dependency, keep the jar file somewhere on your computer and add it to your classpath. Nothing special here.

Make a (new) maven project and include it

Add the following repository:

<repository>
    <id>dj-tcraft repository</id>
    <url>http://ci.dj-tcraft.nl/plugin/repository/everything/</url>
</repository>

And the following dependency (may need to update version):

<dependency>
    <groupId>com.bergerkiller.bukkit</groupId>
    <artifactId>BKCommonLib</artifactId>
    <version>1.54-SNAPSHOT</version>
    <scope>provided</scope>
</dependency>

Dependencies BKCommonLib uses

BKCommonLib supports various other plugins and projects. Below all of these are listed:

Vault - for permission plugin support
ProtocolLib - to avoid packet listening conflicts
Showcase(Standalone) - to ignore showcased items
HyperConomy - to ignore shop items
BleedingMobs - to ignore particles
CGLib - for generating nms.Entity classes on-the-fly to supply Entity Controllers
Objenesis - for generating classes without calling constructors (needed for various fixes inside class constructors)

Plugins that require BKCommonLib to be installed:

Disclaimer

This plugin utilises Hidendra's plugin metrics system, which means that the following information is collected and sent to mcstats.org:

A unique identifier
The server's version of Java
Whether the server is in offline or online mode
The plugin's version
The server's version
The OS version/name and architecture
The core count for the CPU
The number of players online
The Metrics version Opting out of this service can be done by editing plugins/Plugin Metrics/config.yml and changing opt-out to true.

License

This library uses an open license. Feel free to use whatever code you need from it, you do not have to ask me either. If you want me to add certain features, that is fine too. Everyone is allowed to use this Library as a dependency. I do recommend extending 'PluginBase' instead of 'JavaPlugin' then, as it allows you to automatically deal with the BKCommonLib versioning checks. See also: BKCommonLib license file

This product includes software developed by the Apache Software Foundation (http://www.apache.org/)

Compatibility

BKCommonLib supports ProtocolLib when it is enabled, but if it is not, the player connection is replaced resulting in several incompatibilities. To fix these incompatibility issues, install ProtocolLib next to BKCommonLib. This can not be stressed enough. When incompatibility occurs, BKCommonLib will notify you in the console and will disable itself. The following plugins are known to be incompatible when ProtocolLib is NOT installed:

Spout Plugin

Metrics

This plugin sends server count and dependency statistics to MCStats.org. You can (globally) opt out in the PluginMetrics/config.yml file.

Banner

I use a banner in my depending plugins. This banner is automatically updated when a new version of BKCommonLib is out. It is a quick and efficient way to keep track of updates for this library. This was needed, too, because a lot of people were using outdated BKCommonLib versions, which resulted in bug reports...too many of them. And I do not want to waste your time with invalid reports. You have a plugin that uses BKCommonLib? Feel free to use the banner on your download page.
