在java中创建FirefoxDriver时出现java.lang.NoSuchMethodError

时间：2014-09-04 19:51:16

标签： java selenium-webdriver selenium-firefoxdriver

尝试：

WebDriver driver=new FirefoxDriver();

我收到以下错误：

java.lang.NoSuchMethodError: org.openqa.selenium.Proxy.extractFrom(Lorg/openqa/selenium/Capabilities;)Lorg/openqa/selenium/Proxy;
  at org.openqa.selenium.firefox.FirefoxDriver.dropCapabilities(FirefoxDriver.java:313)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:191)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:186)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:182)
  at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:95)

此问题在ubuntu上的firefox更新到32.0版本后立即启动，我尝试安装版本28.0但仍然没有用。

有什么想法吗？ 提前致谢

将驱动程序版本更改为2.39，如 curiosu 所示，新错误显示：

解决方案：我终于设法解决了这个问题，我将selenium webDriver版本从2.42.2更改为2.39.0并将firefox版本从32.0降级到28.0

在Windows 7上对FireFox 32和Selenium Firefox Webdriver 2.40.0的更新有同样的异常。我会在这里发布我的解决方案，也许它不会解决你的问题，但它可能是其他人的解决方案同样的问题，谁在搜索后降落在这里。

selenium-remote-driver以某种方式未正确更新，而selenium-firefox-driver的POM文件中存在<dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-firefox-driver</artifactId> <version>2.43.1</version> </dependency> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-remote-driver</artifactId> <version>2.43.1</version> </dependency> 。我的解决方案是将远程驱动程序添加到我自己的POM中：

{{1}}

我不得不重启我的IDE（IntelliJ）并重建项目，但之后就可以了。

最终配置：

  • FireFox 32.0.3
  • Selenium FireFox驱动程序2.43.1
  • Selenium Remote驱动程序2.43.1

答案 1 :(得分：0)

两者之间存在兼容性问题。简单的方法是找到一个与ubuntu 32.0兼容的版本

答案 2 :(得分：0)

尝试使用旧版版 FirefoxDriver 。

将较旧的FirefoxDriver（例如：2.39）与Firefox 32一起使用。

答案 3 :(得分：0)

请尝试使用较旧的FF版本。目前我也观察到这样的问题FF使用最新的selenium构建没有32但是在将更改恢复到旧版本之后我的问题得到了成功解决。

答案 4 :(得分：0)

如果在导入罐子后第一次执行硒代码

右键单击项目 - ＆gt;构建路径 - ＆gt;配置构建路径...-＆gt;订单和导出 - >获取selenium java，服务器独立罐，就在JRE库下面 - ＆gt;确定

重新执行代码，它会起作用。
