Best use case

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

Teams using java-tooling 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.

# Java Tooling Standards

## **Priority: P2 (RECOMMENDED)**

Standardized build and tooling configuration for consistent environments.

## Implementation Guidelines

- **JDK Setup**: Use **`.sdkmanrc`** or **`.java-version`** to lock the project to **LTS Support (17 or 21)**. Configure Gradle toolchain via `java { toolchain { languageVersion = JavaLanguageVersion.of(21) } }` for reproducible builds.
- **Maven & Wrapper**: Use **`pom.xml`** with **`<dependencyManagement>`**. ALWAYS use the **`mvnw`** wrapper.
- **Gradle & Catalog**: Prefer **`build.gradle.kts`** (Kotlin DSL) with **`libs.versions.toml`** (Version Catalog). Use the **`gradlew`** wrapper.
- **Formatting**: Enforce **Google Style Guide** using **`Spotless`** (`googleJavaFormat()` plugin) or **`Checkstyle`**.
- **Static Analysis**: Integrate **`SpotBugs`** or **`SonarLint`** for deep analysis. Use **`Detekt`** if using Kotlin.
- **Docker**: Use **Multi-stage Dockerfiles**. Use **`eclipse-temurin`** as the base image.
- **CI/CD**: Configure **GitHub Actions** or **GitLab CI** to run `mvnw test` or `gradlew build` on every PR.

## Anti-Patterns

- **No Global Installs**: Always use mvnw/gradlew wrappers; never rely on system Maven/Gradle.
- **No Fat Jars**: Prefer layered Docker images over uber-jars for better layer caching.
- **No Snapshots in Prod**: Never use -SNAPSHOT dependency versions in production builds.
