Welcome to the delightful world of CSS management using Gradle! With the Gradle CSS Plugin, managing your stylesheets has never been easier. Whether you’re a seasoned developer or just starting out, this guide will walk you through everything you need to seamlessly integrate CSS management into your Gradle build process.

Step-by-Step Setup

To get started, you’ll want to add the Gradle CSS Plugin to your project. Here’s how to do it based on your Gradle version:

For Gradle 2.1 and Above

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

For Gradle 2.0

Here’s how to grab the plugin from a Maven repository:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "com.eriwen:gradle-css-plugin:1.11.0"
    }
}
apply plugin: "css"

Defining Your CSS Sources

Next, you’ll need to specify where your CSS files are located. Here’s a simple example:

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

Combining and Minifying CSS Files

Now, let’s combine various CSS files and minify them for a cleaner output. Think of this process like making a smoothie:

• **Combine** your fresh ingredients (CSS files) into one blender (the output file).
• **Minify** the mixture by blending it down to a more compact form (minified CSS).
• **GZip compress** it to keep it fresh and lighter for delivery.

Code to Combine and Minify CSS

combineCss {
    source = css.source.dev.css.files
    dest = "$buildDir/all.css"
}

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

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

LESS Support and CSS Linting

If you’re using LESS, the plugin has got you covered as well:

css.source {
    dev {
        css {
            srcDir "app/styles"
            include "*.less"
            lesscss {
                source = css.source.dev.css.asFileTree
                dest = "$buildDir/styles"
            }
        }
    }
}

csslint {
    source = css.source.dev.css.files
    dest = "$buildDir/csslint.out"
}

Available Tasks and Options

Here’s a brief overview of what tasks you can perform with this plugin:

• combineCss: Merge multiple files into one.
• minifyCss: Reduce file size using YUI Compressor.
• gzipCss: Compress files for better performance.
• less: Transpile LESS stylesheets.
• csslint: Analyze your CSS for errors and warnings.

Troubleshooting

If you encounter any snags while integrating the Gradle CSS Plugin into your project, here are some troubleshooting steps you can follow:

• Check your Gradle version to ensure compatibility with the plugin.
• Make sure that the CSS files specified in your source configurations actually exist.
• If minification fails, verify the configurations for YUI Compressor.
• For GZip issues, ensure you have the necessary permissions on the output directory.
