我按照小教程（如果可以调用它）here来为petstore示例API生成服务器存根 . 然后我按照生成的文件中的 readme 指令进行操作，其中说：

To run the server, please execute the following:

mvn clean package jetty:run


You can then view the swagger listing here:

http://localhost:8080/v2/swagger.json


我第一次这样做，我得到了一个构建和编译错误 . 显然 `pom.xml` 文件缺少Jetty插件：

```xml
<plugin>
          <groupId>org.eclipse.jetty</groupId>
          <artifactId>jetty-maven-plugin</artifactId>
          <version>9.2.9.v20150224</version>
        </plugin>

以及 swagger-core 依赖：

<dependency>
        <groupId>io.swagger</groupId>
        <artifactId>swagger-core</artifactId>
        <version>1.5.9</version>
    </dependency>

虽然它们在 properties 属性下被提及如下：

<properties>
    <swagger-core-version>1.5.9</swagger-core-version>
    <jetty-version>9.2.9.v20150224</jetty-version>
    <resteasy-version>3.0.11.Final</resteasy-version>
    <slf4j-version>1.6.3</slf4j-version>
    <junit-version>4.8.1</junit-version>
    <servlet-api-version>2.5</servlet-api-version>
</properties>

虽然我可以在那之后成功做到 mvn clean package jetty:run ：

我在尝试打开网站时仍然收到404：

$ wget http://localhost:8080/v2/swagger.json

出了什么问题？

编辑：这是我的 mvn clean package -X jetty:run 输出：http://pasted.co/3ceba86c
