Java Crawljax-动态网页爬网需要jars文件

我正在尝试使用Crawljax对javascript网页（IFrame html标记中的内容）进行爬网。我已经在应用程序中添加了slf4j、crawljax 2.1和Guava 18.0 jar

弹出窗口中显示的错误消息：

线程“main”Java结果中出现异常：1

在下面的链接中可以找到相同的代码

有人能告诉我运行这个程序需要什么jars文件吗？或者IDE中是否有任何设置需要更改

谢谢

您似乎正在使用旧版本的crawljax

下载最新版本

将lib文件夹中的所有jar和主文件夹中的crawljax-cli-3.5.1.jar添加为lib路径

---

经过测试，现在运行良好。

您似乎没有添加依赖项。粘贴您的异常和code@Kumar，添加了代码和异常详细信息；我们仅使用最新版本（3.5.1）；还添加了所有jar文件；看来你的自由之路是指旧罐子。删除所有库并从最新包中添加新库。是。。lib path指的是旧罐子我还有一个疑问。。为什么crawljax需要更多的时间来进行单个网站的爬网？您必须参考crawljax网站了解更多信息。@Bass。。我也这样做了；从我的应用程序的lib文件夹中删除所有jar并再次添加引用；仍然不起作用：(
