LibGDX's TexturePacker with gradle

Question

I am attempting to create a gradle task which runs TexturePacker according to the instructions here. (Note that I am using Android Studio and its directory structure rather

I got it working by adding gdx-tools to my buildscript dependencies:

buildscript{
    dependencies {
       ...
       classpath 'com.badlogicgames.gdx:gdx-tools:1.5.4'
    }
}

by doing this, my desktop's build.gradle was able to import the texture packer class:

import com.badlogic.gdx.tools.texturepacker.TexturePacker
task texturePacker << {
    if (project.ext.has('texturePacker')) {
        logger.info "Calling TexturePacker: "+ texturePacker
        TexturePacker.process(texturePacker[0], texturePacker[1], texturePacker[2])
    }
}

please note that your desktop project's ext will need to have texturePacker defined:

project.ext {
    mainClassName = "your.game.package.DesktopLauncher"
    assetsDir = new File("../android/assets");
    texturePacker = ["../images/sprites", "../android/assets", "sprites"]
}
