Now i have setup gradle, it works in Command Prompt what can i do with this via command line?

I have downloaded the latest build of Gradle 2.2, i have setup the path so windows recognizes gradle via command prompt, my question is what can i do with Gradle via the command line, i know it can compile projects, can i download plugins with Gradle by the command line as an example? I would really like to give Gradle a try & make it a good companion for Android Studio.

Plugins are declared in the build script, and downloaded automatically by Gradle. For more information on Gradle, see the Gradle User Guide, the Gradle Android plugin docs, and other resources on the web.
