API

BentoBox uses Maven, and its Maven repository is kindly provided by CodeMC.

Gradle

repositories {
  maven { url "https://repo.codemc.org/repository/maven-public/" }
}

dependencies {
  compileOnly 'world.bentobox:bentobox:PUT-VERSION-HERE-SNAPSHOT'
}

Note: Due to a Gradle issue with versions for Maven, you need to use -SNAPSHOT at the end.

Building from Source

BentoBox builds with Gradle. You do not need to install Gradle — the repository ships the Gradle wrapper, which downloads the exact version the project is built with.

Requirements

• JDK 25 — BentoBox compiles to Java 25 bytecode, because the Paper API it builds against does.
• Git and an internet connection for the first build.

Quick start

git clone https://github.com/BentoBoxWorld/BentoBox.git
cd BentoBox
./gradlew clean build          # use gradlew.bat on Windows

The shaded (fat) jar is written to build/libs/, named BentoBox-<version>.jar — for example build/libs/BentoBox-3.22.1-SNAPSHOT-LOCAL.jar. Drop that straight into your test server's plugins folder.

build runs the tests and produces the shaded jar. If you only want the jar, run ./gradlew clean shadowJar instead.

The first build is slow. The Paperweight plugin downloads and remaps a Paper development bundle before anything compiles. This is a one-off cost — later builds reuse the cached bundle.

Other useful tasks

Command	What it does
./gradlew test	Run the JUnit 5 test suite
./gradlew test --tests "world.bentobox.bentobox.managers.IslandsManagerTest"	Run a single test class
./gradlew test jacocoTestReport	Test with a coverage report in build/reports/jacoco/
./gradlew javadocJar	Build BentoBox-<version>-javadoc.jar
./gradlew sourcesJar	Build BentoBox-<version>-sources.jar
./gradlew publishToMavenLocal	Install to ~/.m2 so a local addon can build against it

Tasks can be combined on one command line, e.g. ./gradlew clean build javadocJar sourcesJar.

If Gradle can't find a Java 25 toolchain

Compilation always happens on Java 25 regardless of which JVM runs Gradle itself. If Gradle reports that no matching toolchain is available, point it at your JDK 25 installation:

./gradlew build -Porg.gradle.java.installations.paths=/path/to/jdk-25

This is what CI does — it runs the Gradle daemon on Java 21 and compiles on a separate Java 25 install discovered via -Porg.gradle.java.installations.fromEnv=JAVA_HOME_25_X64.

Version numbers

The version is derived from buildVersion in build.gradle.kts:

• local builds → 3.22.1-SNAPSHOT-LOCAL
• CI builds → 3.22.1-SNAPSHOT (with the build number recorded separately)
• release builds from origin/master → 3.22.1
