What problem does it solve? Writing Java scripts for the Windmill platform requires following specific structural conventions, such as a public Main class with a static main method, and knowing how to declare Maven dependencies inline. This Skill provides the exact rules and CLI workflow so scripts run correctly on the first attempt. ## Core Features & Use Cases - Java Script Structure: Enforces the required public class Main with a public static Object main(...) entry point and correct return types. - Maven Dependency Management: Shows how to declare dependencies via //requirements: comments, such as Gson or Apache HttpClient. - Windmill CLI Workflow: Guides when to use wmill script preview for local testing versus wmill script run for deployed scripts, and when wmill sync push is appropriate. - Use Case: A developer needs a Java script that parses JSON input with Gson. The Skill produces a compliant Main class, declares the Gson dependency, and previews it locally with sample arguments before any deployment. ## Quick Start Write a Windmill Java script that accepts a name and count parameter and returns them as a map, then preview it locally with sample arguments.
