Exception in thread “main” java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;)

问题

I develop the selenium code that:

    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.chrome.ChromeDriver;
    import org.openqa.selenium.edge.EdgeDriver;
    import org.openqa.selenium.firefox.FirefoxDriver;
    import org.openqa.selenium.support.ui.Select;
    import java.util.List;

    public class TestDemoQA {
        public static void main(String[] args) throws InterruptedException{
            System.setProperty("webdriver.edge.driver", "C:\\Users\\Suganthan\\Downloads\\MicrosoftWebDriver.exe");
            WebDriver driver = new EdgeDriver();
            driver.get("http://demoqa.com/");
            driver.manage().window().maximize();`

I'm getting the error that is:

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)

I'm trying to solve this issue according to This Solution by upgrading guava-21.0. But I'm still getting this error. could anyone give a solution to solve it?

回答1:

This error message...

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)

...implies that the JVM was unable to initiate/spawn your program.

As @GhostCat pointed your main issue is the incompatibility between the guava version and other binary versions you are using.

Solution

Upgrade JDK to recent levels JDK 8u181.
Upgrade Selenium to current levels Version 3.14.0.
When you remove the previous version of Selenium Client ensure that all the associated jars are properly removed.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Execute your @Test.
