Gradle CSS Plugin

Managing your CSS in a Gradle build is super easy now! Just add this to your build.gradle file:

Gradle 2.1+

plugins {
  id "com.eriwen.gradle.css" version "2.14.0"
}

Gradle 2.0-

// Grab the plugin from a Maven Repo automatically
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.eriwen:gradle-css-plugin:1.11.0'
    }
}

// Invoke the plugin
apply plugin: 'css'

// Declare your sources
css.source {
    dev {
        css {
            srcDir "app/styles"
            include "*.css"
            exclude "*.min.css"
        }
    }
}

// Specify a collection of files to be combined, then minified and finally GZip compressed.
combineCss {
    source = css.source.dev.css.files
    dest = "${buildDir}/all.css"
}

minifyCss {
    source = combineCss
    dest = "${buildDir}/all-min.css"
    yuicompressor { // Optional
        lineBreakPos = -1
    }
}

gzipCss {
    source = minifyCss
    dest = "${buildDir}/all.2.0.4.css"
}

LESS Support

css.source {
    dev {
        css {
            srcDir "app/styles"
            include "*.less"
        }
    }
}

lesscss {
    source = css.source.dev.css.asFileTree
    dest = "${buildDir}/styles"
}
