Grain Gradle Plugin

Gradle plugin for Grain framework. Grain is a general purpose static site generator which allows to build websites of any size and complexity, like project and documentation sites or custom blog resources. Grain supports Markdown, RST and AsciiDoc markup rendering, page templates with embedded Groovy code, resource compression and minification, code highlighting using Python Pygments and more.

The plugin allows to create and manage your static website using Gradle, thus making it much easier to create sites for your existing Gradle projects.

Getting Started

To use in Gradle 2.1 and later:

plugins {
  id "com.sysgears.grain" version "0.2.3"
}

repositories {
    mavenCentral()
}

To use in earlier versions of Gradle:

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "gradle.plugin.com.sysgears.grain:grain-gradle-plugin:0.2.3"
  }
}

apply plugin: "com.sysgears.grain"

repositories {
    mavenCentral()
}

Then put a Grain site sources to the src/site directory. For this purpose you can use one of the Grain themes. If you have already downloaded a Grain theme, simply copy its files to the src/site. Alternatively, you may install a theme by running Gradle task of appropriate type. Just copy the following to your build.gradle script:

task grainInstall(type: com.sysgears.grain.gradle.GrainInstallTask) {
    theme = 'template' // theme to install, can be 'template', 'octopress', etc.
    version = '0.4.2'  // theme version
}

If the theme argument isn't specified, Theme Template will be installed by default, and if you don't set the version, the latest available version will be fetched.

As you have added the sources, you can execute the following Gradle tasks:

• gradle grainPreview - launches your website in a preview mode
• gradle grainGenerate - generates all the website files to the destination directory (see filesystem layout)
• gradle grainDeploy - deploys the resulting files (see deployment configuration)
• gradle grainClean - cleans the site destination and target directories

Configuration

Optionally, you can change the site sources directory by specifying the grain.projectDir property:

grain {
    projectDir = '' // relative path to the site sources, default to 'src/site'
}

Also, you can set a specific Grain version, just be sure that it is compatible with your theme:

grain {
    version = '0.6.5' // the Grain version, must be compatible with the theme version
}

To use the latest Grain snapshot, you should define the Sonatype snapshots repository first:

repositories {
    mavenCentral()
    maven {
        url 'https://oss.sonatype.org/content/repositories/snapshots/'
    }
}

grain {
    version = '0.7.0-SNAPSHOT'
}

Advanced Usage

You can run your own Grain commands from the build script. For example, if you have the compress command to gzip site files before deploying, you can simply execute it by the following GrainTask:

task(grainCompress, type: com.sysgears.grain.gradle.GrainTask) {
   command = 'compress' // the name of the custom command
   // arguments = []    // the arguments to pass to the command
   // jvmArguments = [] // JVM arguments to launch Grain process
}
