BKCommonLib
BKCommonLib is no longer being updated on dev.bukkit.org.
If you want to use the latest version, use spigot.
Latest version: 1.57
CraftBukkit/SportBukkit/Spigot/MCPC+ build: CB 1.6.4 R1.0 / CB 1.6.4 R2.1 / Spigot 1.7
Older builds available: CB 1.5.2-R1.0 / CB 1.6.2-R1.0
Tekkit: Untested and thus unsupported, some features may not work as expected
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 This prevents the common mishaps with outdated BKCommonLib versions.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
Features
- General
- PluginBase for easy access to metrics, permissions, localization and more
- Permission defaults for storing the permissions a plugin uses
- Localization for making the messages of a plugin configurable
- Utilities
- General utilities for String, Logic, BlockFace and Math operations
- Block utilities for Block-related operations (states, data, etc.)
- ItemUtil for Inventory, Items and Item Transfer utilities
- RecipeUtil to work with crafting and furnace recipes
- Various Collections for auto-filtering, converting and even interpolation
- Data storage
- Configuration API with nodes, headers and other goodies
- NBT API designed after the configuration API
- (Compressed)DataReader/DataWriter to read and write data from/to file
- Entities
- CommonEntity implementations with added utilities
- EntityController for altering entity behaviour
- EntityNetworkController for altering entity network logic
- Services
- Metrics for keeping track of plugin statistics
- Conversion for conversions between all types of data
- Events and Listeners to keep track of changes on the server
- Packet services and API to keep track of packets
- Task class for easier task scheduling
- Scoreboard services to setup scoreboards without criteria
- Tab View service to alter what is shown when players press tab
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:
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.

Here you go:
https://dl.dropbox.com/u/67122021/plugins/BKCommonLib/BKCommonLib.jar
This is a pre-deb bleeding edge build.
It has not been tested verry well.
Use it at your own risk.
File not approved by BukkitDev staff.
Also posting a dev-link for NoLagg on the NoLagg page.
The orther ones come tomorrow

Posted Mar 15, 2013@ReaperOftheMine I am aware, we are first finishing off any pending things for CB 1.4.7 before we move on. We want to be sure that, while working on 1.5, the previous version had everything working.

Any idea what is wrong with this? I can't tell if it's from Protocolib, BKcommon, or both.

Posted Mar 11, 2013@spawnstah I could not manage to trace it down to a bug in BKCommonLib. The error is occurring in the StatisticsList static initializer, not in BKCommonLib. The reason BKC is shown is because it 'asks' for the Item class, which in turn ends up loading that class. I recommend you report this to md_5 yourself, I have no control over what he breaks.
If this doesn't happen, ever, when using BKCommonLib, let me know. I suspect that this has to do with initialization order or something. I do not have the source with me to check this right now.

Posted Mar 11, 2013Hi Bergerkiller, I just noticed that BKCommonLib works with Spigot #610 but not the new (by md_5) recommended build #611.
I guess it's because of the "Update snapshot version" commit md_5 did for that build.
http://pastebin.com/SLLyLP3j
I've also tried with the latest dev build 1.51 and got the same error.

Posted Mar 10, 2013@Pr07o7yp3 No use commenting this if you do not post the errors. https://pastebin.com/ is your friend, post your server log. No use of using that version, because all plugins that still work on that version had countless of bugs. To be very honest, v1.44 is less stable than v1.50 is right now. I dare to estimate the chance that this is user error to be 90%:

D'oh, my bad. Once I realised BKCL wasn't loading I noticed the conflict error with Spout. Thanks, I got some ProtocolLib on and now I'm all NoLagg'd up again :D

Posted Mar 9, 2013@DilandauMho AFAIK, MCPC+ does not work with BKCommonLib yet. I do notice that a lot of people really want it supported, so I might have to split BKCommonLib up into an API and implementation somehow. There are also several things that do not allow this, like base classes, so I am not sure how to go about that.
MCPC+ support will probably consist of getting plugins supported one-by-one by moving code around and change implementations, but plugins such as TrainCarts and NoLagg will not support this anytime soon. They depend on a lot of net.minecraft.server specific classes.
In the error, CommonUtil.getNMSClass("ItemStack") is returning null, so it should be obvious that it does not support it at all right now.
@WaferMouse The error has to do with BKCommonLib either not being found, or not being loaded for some reason. Are there any other errors? Did you really install the right BKCommonLib version (1.50, the one from dev-bukkit)? And also, there are no duplicates in your plugins folder?

Posted Mar 9, 2013Hi,
I've updated BKCL and My Worlds to the latest versions listed for download, and NoLagg with the version listed in the comments, but I get these errors on startup, with a similar error for My Worlds:
http://pastebin.com/wFyX7QK7
Any help would be great. I'd like to use NoLagg, but I'll have to rollback before My Worlds creepifies safe worlds.
