# JLink Gradle plugin
This project defines a Gradle plugin that enable the use of
[jlink](https://docs.oracle.com/javase/9/tools/jlink.htm) in Gradle builds.
In general, the plugin enables developers to create Java Runtimes with jlink.
It uses the java toolchain to locate the `jlink` executable and creates
a java runtime for your module path based Java application. This
modularization allows small, secure and tailored application distributions.
## Jlink plugin usage
This Gradle plugin integrates with the [Gradle Java Library plugin](https://docs.gradle.org/current/userguide/java_library_plugin.html)
to create distributions automatically using a jlink runtime rather than a user provided JDK runtime.
It applies the `org.xbib.gradle.plugin.jlink` plugin which configures a `jlink` task that executes the jlink tool.
```groovy
plugins {
id 'org.xbib.gradle.plugin.jlink' version "8.8.0"
}
java {
toolchain {
languageVersion.set(JavaLanguageVersion.of(21))
}
}
jlink {
modules.set(List.of("org.example.app"))
launcher.set("app=org.example.app/org.example.app.Main")
stripDebug.set(true)
}
```
In addition, the plugin configures a `jmod` task to download the dependent artifacts on the
runtime class path and create jmod files for the `jlink` task. Also, a `jdeps` task is automatically
configured to show the dependent modules.
The plugin is currently only available under Linux.
