WebDriver Manager java.lang.NoSuchMethodError

Question

I use Java+selenium+testng+maven. And I tried to use WebDriver Manager instead of standard usage. After declaration according to the instruction of API, I ran into a problem. When compiling the errors occurs:

java.lang.NoSuchMethodError: org.apache.commons.io.FileUtils.copyInputStreamToFile(Ljava/io/InputStream;Ljava/io/File;)V

Here is my code frame:

public static WebDriver startBrowser() {

    String browser = Property.getProperties("browser");

    if (browser.equalsIgnoreCase("firefox")) {
        FirefoxDriverManager.getInstance().setup();
        sDriver = new FirefoxDriver();
    } else if (browser.equalsIgnoreCase("chrome")) {
        ChromeDriverManager.getInstance().setup();
        sDriver = new ChromeDriver();
    }

    sDriver.manage().window().maximize();
    sDriver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    return sDriver;
}

And driver usage:

@BeforeClass
public void beforeClass() throws Exception {
    BaseDriver.startBrowser();
}

Answer 1

WebDriverManager 1.7.1 internally use Apache commons-io 2.5. It seems you are using a different version of that library in your project, and a result you get that error.

The easiest solution might be upgrading your commons-io version to 2.5, which is the latest stable version at the moment of this writing.
