// Grab the plugin from a Maven Repo automatically
buildscript {

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"
}
css.source {
dev {
