Gradle Watcher Plugin

A Gradle plugin which watches files/directories for changes and takes actions when changes occur.

Usage

Add the following to your build.gradle in order to use the plugin:

apply plugin: 'gradleWatcherPlugin'

Then configure the list of files/directories you wish the plugin to monitor and what you want to happen when something changes

watch {
    watchJobs {
        // Declare each watch job with a unique name e.g 'less' for watching less files (can be any name you want)
        less {
            // Specify which files/directories should be monitored using the gradle filetree method
            files = fileTree(dir: "${project.rootDir}/public/stylesheets", include: '*.less')
            // specify the shell command to execute if any changes are detected in your files
            taskToRun = "lessc --verbose --source-map-url=style.map --source-map=${project.rootDir}/public/stylesheets/style.map ${project.rootDir}/public/stylesheets/style.less ${project.rootDir}/public/stylesheets/style.css"
        },
        js {
            files = fileTree(dir: "${project.rootDir}/public/js", include: '**/*.js')
            taskToRun = ...
        },
        someOtherJob {
            files = fileTree(...),
            taskToRun = ...
        }
    }
}

The plugin adds a single task called watchFiles which when run will use the watch configuration above to decide which files/directories to watch and what to do when they change.
