Getting Started

Compatibility

This plugin requires link::http://gradle.org[Gradle] 2.0 or better

Installing

build.gradle

buildscript {
    repositories { jcenter() }

    dependencies {
        /* check jruby-gradle.org for the latest release */
        classpath "com.github.jruby-gradle:jruby-gradle-jar-plugin:[1.1.4,2.0)"

Implicitly loaded plugins

Currently, the jar plugin only depends on the base plugin of the same version as the jar plugin and the java-base plugin included with your version of Gradle.

Tasks

JRubyJar

build.gradle

jrubyJar {
    /* All methods and properties from `Jar` */
    from 'app'
}

Runnable Jars

build.gradle

jrubyJar {
    // tell the plugin to pack a runnable jar
    initScript runnable()

    // Use the default bootstrap class (can be omitted)
    defaultMainClass()

    // Make the JAR executable by supplying your own main class
    mainClass 'my.own.main'
}

Library Jars

A library jar isn’t really much more than a container which includes the configured gems and jar dependencies inside of the packaged .jar file.

build.gradle

jrubyJar {
    // tell the plugin to pack a runnable jar (no bootstrap script)
    initScript library()
}
