## What it does

The skill inspects local tooling: Java 17, 21, or 25, build tools like `mvn` or `gradle`, and optional Quarkus CLI. If an existing Quarkus BOM or plugin is detected, scaffolding stops immediately to prevent overwriting project files. New setups pick the recommended LTS stream directly from the `code.quarkus.io` API, deliberately avoiding Quarkus 4.0 beta releases.

Bootstrapping works via `quarkus create app`, the `quarkus-maven-plugin`, or fetching an archive straight from the online API. It assigns standard extension bundles like `rest-jackson`, `hibernate-orm-panache`, and `smallrye-health`. If a requested extension is absent from the selected LTS stream, the CLI silently downgrades to an older stream, requiring a manual check of `quarkus.platform.version`.

Running `./mvnw quarkus:dev` or `./gradlew quarkusDev` starts live reload alongside Dev Services and the Dev UI console at `http://localhost:8080/q/dev-ui`. Integration test classes ending in `*IT` are skipped by default in Maven; passing `-DskipITs=false` executes them.

## Install

### GitHub Copilot (native platform)

1. **GitHub CLI**
```bash
gh skill install github/awesome-copilot create-quarkus-project
```

2. **Manually: put the files in place**
- File: `.github/skills/create-quarkus-project/SKILL.md`

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add github/awesome-copilot --skill create-quarkus-project -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/create-quarkus-project/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/create-quarkus-project/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/create-quarkus-project/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/create-quarkus-project/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/github/awesome-copilot --path skills/create-quarkus-project
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/create-quarkus-project/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/skills/create-quarkus-project/SKILL.md

## When to use it
- Scaffold a Quarkus service targeting Java 21 or Java 25
- Add extensions for persistence, health checks, and JSON APIs
- Configure Maven or Gradle build tooling automatically
- Start the local runtime with live reload and Dev UI

## Example prompts
- Scaffold a new Quarkus application using Java 21 and Maven
- Create a Quarkus project with extensions for database access and health checks
- Launch the current Quarkus project in dev mode with live reload

description: 'Create a new Quarkus project (Maven or Gradle) with the Quarkus CLI, code.quarkus.io API or Maven plugin, choose extensions, and run it in dev mode. Use when asked to scaffold, bootstrap or start a Quarkus application or REST API.'

# Create a Quarkus Project

## 1. Detect the environment

```bash
java -version          # Java 17, 21 or 25 (Quarkus 3.40 recommends 25, 3.27 recommends 21)
quarkus --version      # optional Quarkus CLI
./mvnw -v || mvn -v    # or ./gradlew -v
```

If the folder already contains a Quarkus project (`io.quarkus.platform` BOM, `quarkus-maven-plugin`, or `io.quarkus` Gradle plugin), do NOT scaffold: read its Quarkus version and keep it. For a new project, use the stream marked recommended on https://code.quarkus.io/api/streams (an LTS stream; see also https://quarkus.io/support/), and do not invent a patch version: let the tool pick it. Quarkus 4.0 is still a beta, so do not use it unless asked. If an extension is missing from the recommended stream, the CLI silently picks an older stream; check `quarkus.platform.version` in the generated build file.

## 2. Scaffold (pick one)

Quarkus CLI (install via https://quarkus.io/get-started/ , e.g. SDKMAN `sdk install quarkus`):

```bash
quarkus create app com.example:demo \
  --extension='rest-jackson,hibernate-orm-panache,jdbc-postgresql,hibernate-validator,smallrye-health' \
  --java=21 --maven        # or --gradle
```

No CLI: Maven plugin (pin the version to the current release from https://quarkus.io/guides/maven-tooling, replace `QUARKUS_VERSION` below with it):

```bash
mvn io.quarkus.platform:quarkus-maven-plugin:QUARKUS_VERSION:create \
  -DprojectGroupId=com.example -DprojectArtifactId=demo \
  -Dextensions='rest-jackson,hibernate-orm-panache,jdbc-postgresql' \
  -DbuildTool=maven        # or gradle
```

Or generate from the https://code.quarkus.io web UI / REST API (`https://code.quarkus.io/d?g=com.example&a=demo&e=rest-jackson&b=MAVEN`) and unzip.

## 3. Choose extensions

| Need | Extension |
|---|---|
| REST + JSON | `rest-jackson` (Quarkus REST; not legacy `resteasy`) |
| Database ORM | `hibernate-orm-panache`, `jdbc-postgresql` |
| Validation | `hibernate-validator` |
| Health / metrics | `smallrye-health`, `micrometer-registry-prometheus` |
| Auth | `oidc` or `smallrye-jwt` |
| OpenAPI | `smallrye-openapi` |
| REST client | `rest-client-jackson` |
| Container | `container-image-jib` (or `container-image-docker`) |

Add later with `quarkus extension add <name>` or `./mvnw quarkus:add-extension -Dextensions=<name>`; `quarkus extension list --installable` lists options.

## 4. Layout and run

```
src/main/java/...          # resources, services, entities
src/main/resources/application.properties
src/main/docker/           # Dockerfile.jvm, Dockerfile.native, ...
src/test/java/...          # @QuarkusTest / @QuarkusIntegrationTest
```

```bash
./mvnw quarkus:dev         # or: quarkus dev / ./gradlew quarkusDev
```
