LWJGL3 Gradle Plugin

A Gradle plugin to simplify working with LWJGL 3.

Usage

Note

The documentation of this plugin is written in Gradle's Kotlin DSL. The plugin can also be used with Groovy build scripts and all concepts still apply but the exact syntax may differ.

Applying the Plugin

plugins {
    id("com.osmerion.lwjgl3") version "0.4.0"
}

Targets

The plugin introduces the concept of "targets" to enable using multiple different LWJGL setups (different versions, modules, etc.) within a single Gradle project. In the following example, a target is registered and linked to the appropriate configurations.

val lwjgl3MainTarget = targets.register("main")

configurations.named("implementation") {
    extendsFrom(lwjgl3MainTarget.get().libConfiguration.get())
}

configurations.named("runtimeOnly") {
    extendsFrom(lwjgl3MainTarget.get().nativesConfiguration.get())
}

The configuration libConfiguration contains all Java library dependency artifacts and the configuration nativeConfiguration includes the artifacts containing the native libraries for LWJGL for the current host.

Important

By default, a main target as defined above is automatically registered when the org.gradle.java plugin is detected. To disable this behavior, set the property com.osmerion.lwjgl3.implicit-target to false.

Modules

LWJGL consists of many modules which contain bindings to different native libraries. Modules can be added to a target as follows:

lwjgl3 {
    targets.named("main") {
        modules.add(Lwjgl.Core)
    }
}

Predefined accessors for known LWJGL modules are available in the Lwjgl class.

Custom Modules

In addition to using the predefined module accessors, it is also possible to use custom modules. This can be useful when working with forked versions of LWJGL or for new modules for which no predefined accessors are available yet.

lwjgl3 {
    targets.named("main") {
        modules.add("lwjgl-glfw")
    }
}

Platforms

As LWJGL provides bindings to native libraries, it is also necessary to declare which native platforms should be included in a target. FunSeveral functions are available for LWJGL targets and can be used to include a predefined platform. E.g.:

lwjgl3 {
    targets.named("main") {
        windowsX64()
    }
}

The following predefined platforms are available:

• freebsdX64
• linuxARM32, linuxARM64, linuxPPC64LE, linuxRISCV64, linuxX64
• macosARM64, macosX64
• windowsARM64, windowsX64, windowsX86

Custom Platforms

Additionally, custom platforms can be declared using the platform function. This is mostly useful when porting LWJGL to new platforms or when the plugin has not been updated yet to include new predefined functions.

lwjgl3 {
    targets.named("main") {
        platform(name = "FreeBSDX64") {
            artifactClassifier.set("natives-freebsd")

            match {
                os.set(OperatingSystem.FreeBSD)
                arch.set(Architecture.X86_64)
            }
        }
    }
}

Configuring the LWJGL Artifacts

The plugin can further be customized to use a different version of LWJGL by configuring the version property of a target. Similarly, the group property can be used to configure the group name portion of the GAV coordinates for the LWJGL artifacts.

lwjgl3 {
    targets.named("main") {
        group.set("org.lwjgl")
        version.set("3.3.4")
    }
}

Building from source

Setup

This project uses Gradle's toolchain support to detect and select the JDKs required to run the build. Please refer to the build scripts to find out which toolchains are requested.

An installed JDK 1.8 (or later) is required to use Gradle.

Building

Once the setup is complete, invoke the respective Gradle tasks using the following command on Unix/macOS:

./gradlew <tasks>

or the following command on Windows:

gradlew <tasks>

Important Gradle tasks to remember are:

• clean - clean build results
• build - assemble and test the Java library
• publishToMavenLocal - build and install all public artifacts to the local maven repository

Additionally tasks may be used to print a list of all available tasks.
