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

Question

试图:

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)

这个问题在ubuntu上的firefox更新到32.0版本之后就开始了,我试着安装28.0版但是仍然无法正常工作.

有任何想法吗？提前致谢

将驱动程序版本更改为2.39后像curiosu所说,一个新的错误显示:

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

Answer 1

曾与更新到Firefox 32和火狐硒webdriver的2.40.0相同的异常在Windows 7上,我会在这里发布我的解决方案,也许它不会解决你的问题,但它可能是同样的问题对他人的解决方案谁搜索后到这里.

不知何故,selenium-remote-driver它没有得到正确更新,而它存在于POM文件中selenium-firefox-driver.我的解决方案是将远程驱动程序添加到我自己的POM中:

<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>

我不得不重新启动我的IDE(IntelliJ)并重建项目,但之后它才有效.

最终配置:

• FireFox 32.0.3
• Selenium FireFox驱动程序2.43.1
• Selenium远程驱动程序2.43.1

Answer 2

您两者之间存在一些兼容性问题。最简单的方法是找到与 ubuntu 32.0 兼容的版本
