 * <h3>Purpose</h3>
 *
 * <p>The main purpose of {@code ListenableFuture} is to help you chain together a graph of
 * asynchronous operations. You can chain them together manually with calls to methods like {@link

    /** The component <code>role</code> hint for Plexus container */
    String ROLE = Mojo.class.getName();

    /**
     * Perform whatever build-process behavior this <code>Mojo</code> implements.<br>
     * This is the main trigger for the <code>Mojo</code> inside the <code>Maven</code> system, and allows
     * the <code>Mojo</code> to communicate errors.
     *
     * @throws MojoExecutionException if an unexpected problem occurs.

### 프로젝트 파일 구조 { #project-file-structure }

프로젝트 파일 구조가 다음과 같다고 해봅시다:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
```

이제 해당 정적 파일을 저장할 디렉터리를 만드세요.

새 파일 구조는 다음과 같을 수 있습니다:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
└── static/
```

### 파일 다운로드하기 { #download-the-files }

문서에 필요한 정적 파일을 다운로드해서 `static/` 디렉터리에 넣으세요.
