Create Micronaut Maven Project

Create a new Micronaut Maven project through SDKMAN-managed tooling, aligned with Java 25 and the repository's Micronaut 4.x baseline.

**What is covered in this Skill?**

• Verify SDKMAN and Java availability before project creation
• Install or select the required Java and Micronaut CLI candidates through SDKMAN
• Gather project coordinates, package name, Java version, features, and target directory
• Create a Maven project with the Micronaut CLI
• Prefer Maven wrapper commands for validation
• Verify the generated project with Maven before reporting completion

Constraints

Project creation must be explicit, reproducible, and Maven-based.

• **PREREQUISITE**: Verify SDKMAN is installed with `sdk version`; if missing, stop and provide setup guidance instead of installing it silently
• **JAVA BASELINE**: Prefer Java 25 unless the user requests another supported version
• **FRAMEWORK BASELINE**: Target the current Micronaut 4.x line by default
• **BUILD TOOL**: Generate a Maven project, not Gradle
• **SAFETY**: Do not overwrite an existing non-empty target directory without explicit user confirmation
• **VERIFY**: Run `./mvnw clean verify` from the generated project when the Maven wrapper exists; otherwise run `mvn clean verify`
• **BEFORE APPLYING**: Read the reference for the full SDKMAN and Micronaut CLI workflow

When to use this skill

• Create a Micronaut Maven project
• Bootstrap Micronaut project with SDKMAN
• Generate a new Micronaut service
• Create Micronaut 4 Maven project
• Scaffold Micronaut service with Java 25

Workflow

1. **Read reference and gather project inputs**

Read `references/500-frameworks-micronaut-create-project.md`, then gather project directory, group, artifact, package name, Java version, application type, and desired Micronaut features.

2. **Verify SDKMAN-managed tooling**

Check SDKMAN, Java, and Micronaut CLI availability. Install or switch candidates only after confirming the intended versions with the user.

3. **Create the Maven project**

Use the Micronaut CLI to create a Maven project, keeping features explicit and the Micronaut 4.x baseline as the default.

4. **Verify and report**

Run Maven verification in the generated project and summarize commands used, selected options, generated path, and any follow-up setup.
