## Development Workflow

### Build Commands

```bash
mvn clean install              # Build all
mvn clean install -DskipTests  # Skip tests
mvn test                       # Run tests
mvn formatter:format           # Format code
mvn license:format             # Update license headers
```

### Code Style

            final MavenSession currentSession,
            final MavenProject mavenProject,
            Throwable t,
            final Instant buildStartTime) {
        // record the error and mark the project as failed
        Instant buildEndTime = MonotonicClock.now();
        buildContext.getResult().addException(t);
        buildContext
                .getResult()

# 表单数据

接收的不是 JSON，而是表单字段时，要使用 `Form`。

/// info | 说明

要使用表单，需预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如，`pip install python-multipart`。

///

## 导入 `Form`

从 `fastapi` 导入 `Form`：

{* ../../docs_src/request_forms/tutorial001.py hl[1] *}

## 定义 `Form` 参数

创建表单（`Form`）参数的方式与 `Body` 和 `Query` 一样：

## **2. Prerequisites**

- Install Hortonworks Distribution using this [guide.](https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.1.0/bk_ambari-installation/content/ch_Installing_Ambari.html)

Erstellen Sie unbedingt eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank}, aktivieren Sie diese und installieren Sie dann das Paket, zum Beispiel:

```console
$ pip install python-multipart
```

///

## `Form` importieren { #import-form }

Importieren Sie `Form` von `fastapi`:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[3] *}

etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines.

## Get started

### 1. Prerequisites

- Docker 18.03 or above, refer here for [installation](https://docs.docker.com/install/).

### 2. Start etcd

etcd uses [gcr.io/etcd-development/etcd](https://console.cloud.google.com/gcr/images/etcd-development/GLOBAL/etcd) as a primary container registry.

```

/// info | 정보

이를 사용하려면 `orjson`을 설치해야합니다. 예: `pip install orjson`.

///

### `UJSONResponse`

<a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>을 사용한 또 다른 JSON 응답 형식입니다.

/// info | 정보

이 응답을 사용하려면 `ujson`을 설치해야합니다. 예: 'pip install ujson`.

///

/// warning | 경고

        //                                      Collection<? extends MetadataRequest> requests );
    }

    @Test
    void testInstall() throws Exception {
        // InstallResult install( RepositorySystemSession session, InstallRequest request )
        //                throws InstallationException;
        // release, snapshot unique ou non unique, attachment
    }

    @Test

        mavenExecutionRequest.setExecutionListener(new AbstractExecutionListener());
        mavenExecutionRequest.setGoals(Arrays.asList("clean", "aggr", "install"));
        mavenExecutionRequest.setDegreeOfConcurrency(1);
        final MavenSession session = new MavenSession(null, null, mavenExecutionRequest, defaultMavenExecutionResult);
