| # Glowstone |
| |
| A fast, customizable and compatible open source server for Minecraft: Java Edition. |
| |
| ## Introduction |
| |
| Glowstone is a lightweight, from scratch, open source |
| [Minecraft](http://minecraft.net) server written in Java that supports plugins |
| written for the Bukkit API and its major forks, Spigot and Paper. |
| |
| The main goals of the project are to provide a lightweight implementation |
| of the Bukkit API and Minecraft server where exact vanilla functionality is |
| not needed or higher performance is desired than the official software can |
| deliver. Glowstone makes use of a thread-per-world model and performs |
| synchronization only when necessitated by the Bukkit API. |
| |
| Still have questions? Check out our [FAQ](https://github.com/GlowstoneMC/Glowstone/wiki/Frequently-Asked-Questions). |
| |
| ## Features |
| |
| Glowstone has a few key advantages over CraftBukkit: |
| * It is **100% open source**. While CraftBukkit and most other mods are open |
| source, they rely on decompiled Minecraft source code. Glowstone's code is |
| completely original. |
| * Because of this, it is easy to contribute to Glowstone's development. The |
| barrier of entry to contributions is lower because there is no need to work |
| around decompiled source or maintain a minimal diff. |
| * Glowstone supports all plugins written for the Bukkit, Spigot and Paper APIs natively. In |
| practice, some plugins may try to make use of parts of the API which are not |
| yet implemented, but in a completed state Glowstone would support all Bukkit plugins. |
| * Glowstone's simplicity affords it a performance improvement over CraftBukkit |
| and other servers, making it especially suited for situations where a large |
| amount of players must be supported but vanilla game features are not needed. |
| |
| However, there are several drawbacks: |
| * Glowstone **is not finished**. Nothing is guaranteed to work, though many things |
| are likely to. If in doubt, file an issue. |
| * Bukkit plugins which expect the presence of CraftBukkit-specific code |
| (that are in the `org.bukkit.craftbukkit` or `net.minecraft.server` packages) |
| will not work on Glowstone unless they are designed to fail gracefully. |
| * Glowstone is not produced by the Bukkit team, and while we do make an effort |
| to produce quality work, Glowstone does not undergo the same rigorious testing |
| as the Bukkit project. |

| ## Downloads |
| [](https://circleci.com/gh/GlowstoneMC/Glowstone) |
| |
| If you don't want to build from source, pre-built jar files are available to download from [**CircleCI**](https://circleci.com/gh/GlowstoneMC/Glowstone) - click the latest build and then open the "Artifacts" tab **(you must be logged in for this to show)**. |
| |
| ## Building |
| |
| |
| ### 1. Setup |
| After installing [Oracle JDK](http://oracle.com/technetwork/java/javase/downloads) (recommended) or [OpenJDK](http://openjdk.java.net/), and |
| [Maven](https://maven.apache.org), checkout the source: |
| |
| ```sh |
| git clone https://github.com/GlowstoneMC/Glowstone |
| cd Glowstone |
| ``` |
| |
| ### 2. Build |
| |
| ```sh |
| ./setup.sh |
| ``` |
| |
| The final jar will be placed in `target/` named `glowstone.jar`. |
| |
| ## Running |
| |
| Running Glowstone is simple because its dependencies are shaded into the output |
| jar at compile time. Simply execute `java -jar glowstone.jar` along with any |
| extra JVM options desired (we recommend using `java -Xms1G -Xmx1G -XX:+UseG1GC -jar glowstone.jar`). A variety of command-line options are also available - |
| run `java -jar glowstone.jar --help` for more information. |
| |
| By default, configuration is stored in the `config/` subdirectory and logs |
| are stored in the `logs/` subdirectory. The main configuration file is |
| `config/glowstone.yml`, which replaces CraftBukkit's `server.properties` and |
| `bukkit.yml`. Settings from these two files will be copied over to Glowstone's |
| configuration during the default configuration generation process. |
| |
| Glowstone uses [JLine](http://jline.github.io/jline2/) for console input and colored |
| console output. The JLine console can be disabled in the configuration if a |
| flat console is desired. |

| maintaining and configuring your Glowstone server. |

| ## Playing |
| |
| For those of you who just want to play on a Glowstone server, we have one available |
| for testing at `mc.glowstone.net`. Have fun! |
