java.lang.NoSuchMethodError while creating a FirefoxDriver in java

Question

While trying to:

WebDriver driver=new FirefoxDriver();

I get the following error:

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)

This problem started right after firefox on ubuntu updated to 32.0 version, I tried to install version 28.0 but still didn't worked.

Any ideas? Thanks in advance

After changing drivers version to 2.39 like curiosu said, a new error shows:

Solution: I finally managed to resolve the problem, I changed selenium webDriver version from 2.42.2 to 2.39.0 and downgraded firefox version from 32.0 to 28.0

Answer 1

Had the same Exception with the update to FireFox 32 and Selenium Firefox Webdriver 2.40.0 on Windows 7. I'll post my solution here, maybe it won't solve your problem but it could be the solution for others with the same problem who land here after searching.

Somehow the selenium-remote-driver does not get correctly updated, while it is present in the POM file for the selenium-firefox-driver. My solution was adding the remote driver to my own POM:

<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>

I had to restart my IDE (IntelliJ) and rebuild the project, but after that it worked.

Final config:

• FireFox 32.0.3
• Selenium FireFox driver 2.43.1
• Selenium Remote driver 2.43.1
