java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;) with Selenium, gradle and ChromeDriver

问题

I am trying to use Selenium api with Gradle. This is my build.gradle dependency section:

dependencies {
    compile 'com.google.api-client:google-api-client:1.23.0'
    compile 'com.google.oauth-client:google-oauth-client-jetty:1.23.0'
    compile 'com.google.apis:google-api-services-sheets:v4-rev506-1.23.0'
    compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version:        '2.9.0'
    compile group: 'org.seleniumhq.selenium', name: 'selenium-chrome-driver', version: '2.9.0' }

My selenium - Java code:

System.setProperty("webdriver.chrome.driver", "C:\\Program Files(x86)\\Google\\Chrome\\Application\\chrome.exe");
WebDriver driver = new ChromeDriver();

Code works fine, and I am able to get Chrome browser opened. However, in build.gradle, I am using 2.9.0 version of selenium and chromedriver. If I try to use any version after 2.9.0, it gives me below error in WebDriver driver = new ChromeDriver(); method:

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;)V

        at org.openqa.selenium.chrome.ChromeDriverService$Builder.findDefaultExecutable(ChromeDriverService.java:137)

        at org.openqa.selenium.chrome.ChromeDriver.<init>(ChromeDriver.java:123)
        at Quickstart.main(Quickstart.java:130)

I tried looking for gradle+Maven+selenium supported version. Was not able to find any good info. Any idea?

回答1:

Try to update your Guava to

<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>27.1-jre</version>
</dependency>

It will solve your issue.

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;)V

...implies that the Java Client was unable to find ChromeDriver().

Issue & Solution

As per the Selenium - Java code you have shared, the System.setProperty() line is used to set the ChromeDriver binary path not the chrome binary path. For that you have to download the ChromeDriver binary from the ChromeDriver - WebDriver for Chrome and place it in your system and mention the absolute path of the ChromeDriver through System.setProperty() line. Hence you have to change :

System.setProperty("webdriver.chrome.driver", "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
WebDriver driver = new ChromeDriver();

To :

System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
WebDriver driver = new ChromeDriver();

I have the exact same problem (I am using Maven though).

I noticed that the problem is that using one of com.google.api-client, or com.google.oauth-client, or com.google.apis:google-api-services-sheets alongside org.seleniumhq.selenium causes the error.

The problem is that both dependencies depend on a different com.google.guava:guava artifact.

In order to solve the error, you should explicitly depend on a single com.google.guava:guava artifact. So go ahead and add the following in your build.gradle:

compile 'com.google.guava:guava:27.0.1-jre'

Just wanted to post here in case anyone else comes to this from Google like I did. For whatever reason, I needed to run with sudo. I was having issues using the npm selenium-standalone package and running:

/node_modules/selenium-standalone/bin/selenium-standalone start

And it would show that error. What fixed it was running with sudo

sudo /node_modules/selenium-standalone/bin/selenium-standalone start

I don't think I needed to do this before but suddenly it's the only way it works now.

回答5:

I had the same problem and ran a dependency check and found that there were conflicts. The solution that worked for me was to exclude the conflicting dependencies.

Your project will probably have different dependencies than mine. So, listing the specific conflicts in my project may not be helpful.
