Wro4J Gradle Plugin

Provides build-time solution for wro4j with Gradle.

Latest release: 1.8.0.Beta4

Getting Started

You could find complete example here

Step 1. Layout your web sources

Put your web sources (html, js, css, less, etc) in the following folders:

src/
  main/
    webResources/
      js/
        *.js
      themes/
        default/
          images/
            *.png; *.gif; ...
          *.css; *.less; ...
      static/
        index.html; ...

Plugin treats all paths against $projectDir/src/main/webResources. Files from static folder will be copied to output as is by default but for js and css it is necessary to provide bundle configuration (see step 4).

Step 2. Apply plugin

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'ro.isdc.wro4j.gradle:wro4j-gradle-plugin:1.8.0.Beta4'
    }
}
apply plugin: 'java'
apply plugin: 'wro4j'

Wro4J plugin requires Java plugin to be applied first.

Step 3. Add webjar dependencies

dependencies {
    webjars 'org.webjars:jquery:2.1.4'
    webjars 'org.webjars:bootstrap:3.3.4'
}

Step 4. Define bundles

webResources {
    bundle ('core') {
        js 'js/**/*.js'
        preProcessor 'jsMin'
    }

    bundle ('libs') {
        js 'webjars/jquery/2.1.4/jquery.min.js'
    }

    bundle ('theme-default') {
        css 'webjars/bootstrap/3.3.4/less/bootstrap.less'
        css 'themes/default/main.css'

        cssOverrideImport 'variables.less', '../../../../themes/default/variables.less'
        preProcessor 'less4j', 'cssUrlRewriting'
    }

    assets {
        include 'themes/default/images/**'
    }
}

You could reference webjar's content just using webjars/ prefix, e.g. webjars/bootstrap/3.3.4/less/bootstrap.less.

Step 5. Build

gradlew build

When build finished you will get a jar with the following resources:

static/
  themes/
    default/
      images/
        *.png; *.gif; ...
    core.js
    libs.js
    theme-default.css
    index.html; ...
