Maven JLink Plugin Version 3.1.0 released

The Apache Maven team is pleased to announce the release of the Apache Maven JLink Plugin, version 3.1.0.

This plugin is used to create a JLink distribution using Maven. It is as easy as creating a jar file, but will instead create a zip file containing a reduced Java Runtime along with a launcher script, as well as the actual application of course. A JLink zip file is therefore platform dependent.

Disclosure: I am a maven committer, not a PMC member.

Quick Usage Guide

To create a module with a JLink zip file as its primary artifact, specify its packaging type and add the plugin as an extension:

<project …>
  <modelVersion>4.0.0</modelVersion>

  <packaging>jlink</packaging>

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jlink-plugin</artifactId>
        <version>3.1.0</version>
        <extensions>true</extensions>
        <configuration>
          <!-- optionally, create a launcher -->
          <launcher>reactorapp=com.reactor.project.app/com.reactor.project.app.App</launcher>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

It is also possible to add a JLink zip file as an additional artifact to your project. Please note that at the moment you need to specify a classifier:

<project …>
  <modelVersion>4.0.0</modelVersion>

  <packaging>jar</packaging>

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jlink-plugin</artifactId>
        <version>3.1.0</version>
        <configuration>
          <classifier>dist-${os}</classifier>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>
