我正在开发 YouTube 广播示例 java 程序。我创建了一个示例程序，从

https://github.com/youtube/api-samples/tree/master/java

而且，我已经导入了必要的依赖项/jars。但是，当我尝试运行程序时，它会在这一行抛出异常：

LocalServerReceiver localReceiver = new LocalServerReceiver.Builder().setPort(8080).build();

以下例外：

Throwable: org/mortbay/jetty/Handler

当我导入org.mortbay.jetty.jar

我得到这个例外：

如果您使用的是 maven，请将此 jar 包含在您的pom.xml

<dependency>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty</artifactId>
    <version>6.1.5</version>
</dependency>

否则，您可以下载此 jarorg.mortbay.jetty.jar并将其包含在内。
