I’m facing an issue when I try to initiate the headless browser with Phantomjs. The error displayed is: “java.lang.NoSuchMethodError: org.openqa.selenium.os.CommandLine.find(Ljava/lang/String;)Ljava/lang/String;”. This occurs at various points in the PhantomJSDriverService. I am using a Mac operating system. My setup for launching the headless browser is: File executable = new File(“src/test/resources/phantomjs_mac”); System.setProperty(“phantomjs.binary.path”, executable.getAbsolutePath()); driver = new PhantomJSDriver(); The full error trace includes multiple calls in the code related to the PhantomJSDriver, and it seems to be failing during the configuration phase. Could someone please assist me in resolving this?
The java.lang.NoSuchMethodError
you are encountering typically indicates a mismatch between different versions of libraries being used within your project. In your case with PhantomJS, it suggests that the Selenium version being used does not match the expected API of PhantomJSDriverService.
Here are some strategies to resolve this issue:
- Check your Selenium and WebDriver Dependency Versions:
Ensure that you are using compatible versions of Selenium and WebDriver for PhantomJS. Refer to the official documentation or the Maven repository for the correct version compatibility references. - Update Project Dependencies:
Sometimes, updating your dependencies to the latest stable versions can resolve compatibility issues. Make sure to update yourpom.xml
if using Maven orbuild.gradle
for Gradle to reflect these changes. - Consider Alternative Headless Browsers:
As PhantomJS is no longer actively maintained, consider using alternative headless browsers like Headless Chrome or Firefox, which are more commonly supported and integrated with Selenium: - Library Conflicts and Classpath Inspection:
Verify that no outdated or conflicting JAR files are present in your project’s classpath. Occasionally, IDEs or build tools might include unintended libraries.
System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
WebDriver driver = new ChromeDriver(options);
By approaching the issue from these angles, the likelihood is high that you’ll isolate the root cause of the version mismatch and successfully resolve the problem you're encountering with the PhantomJS setup.
