Best use case

groovy is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Groovy scripting for JVM, Gradle builds, and Jenkins pipelines. Use for .groovy files.

Teams using groovy should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# Groovy

Groovy v4 adds **Switch Expressions**, Records, and Sealed Types. It remains the key to **Gradle** and Jenkins Pipelines.

## When to Use

- **Build Automation**: Writing `build.gradle` scripts.
- **CI/CD**: Writing Jenkinsfiles.
- **Scripting JVM**: Interacting with Java libraries dynamically.

## Core Concepts

### Closures

`{ item -> item.name }`. The core functional primitive.

### Dynamic Typing

`def x = 1`. (Though `@CompileStatic` can force types).

### Builders

`JsonBuilder`, `MarkupBuilder` for generating hierarchical data.

## Best Practices (2025)

**Do**:

- **Use `@CompileStatic`**: For performance critical code (production logic).
- **Use Spock**: The best testing framework on the JVM (written in Groovy).
- **Use `def` sparingly**: Type your variables if you know them.

**Don't**:

- **Don't mix logic in Gradle**: Keep build scripts declarative. Move logic to `buildSrc`.
