Java HTMLUnit getPage NoClassDefFoundError

我遇到以下源代码的问题：

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.NicelyResynchronizingAjaxController;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.WebRequest;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

import java.net.URL;

/**

public class Parser {

    public static void main(String[] args) throws Exception {

        WebClient webClient = new WebClient(BrowserVersion.FIREFOX_17);
        webClient.setAjaxController(new NicelyResynchronizingAjaxController());

        WebRequest request = new WebRequest(new URL("http://oddsportal.com"));
        HtmlPage page = webClient.getPage(request);

        int i = webClient.waitForBackgroundJavaScript(1000);

        while (i > 0)
        {
            i = webClient.waitForBackgroundJavaScript(1000);

            if (i == 0)
            {
                break;
            }
            synchronized (page)
            {
                System.out.println("wait");
                page.wait(500);
            }
        }

        webClient.getAjaxController().processSynchron(page, request, false);

        System.out.println(page.asXml());

    }
}

这是错误消息：

我读了很多关于这个主题的文章，包括从浏览器版本到WebClient，切换到org.apache.httpcomponents的旧版本4.2，尝试按照另一个主题中的说明转换HtmlPage，但没有任何帮助。我只想加载一个特定的页面并等待javascript执行，然后用jsoup解析它。提前感谢您的帮助

问候,，

虽然您尚未解释到目前为止您所做的哪些工作导致了该错误，但我猜您尚未导入适当的库。确保导入HTMLUnit发行版中的所有库

您可以在下面的问题中了解如何在Eclipse中实现这一点，也许这会有所帮助：

顺便说一下，没有必要切换到任何旧版本。只需导入库就可以了。

我正在使用maven，所以我添加了依赖项。net.sourceforge.htmlunit htmlunit 2.13当我添加htmlunit-2.13-bin.zip时，它工作了，很奇怪为什么maven没有。。非常感谢。
