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

标签： java selenium gradle selenium-webdriver selenium-chromedriver

我正在尝试将Selenium api与Gradle一起使用。这是我的build.gradle依赖部分：

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' }

我的selenium - Java代码：

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

代码工作正常，我可以打开Chrome浏览器。 但是，在build.gradle中，我使用的是2.9.0版本的selenium和chromedriver。如果我尝试在2.9.0之后使用任何版本，它会在WebDriver driver = new ChromeDriver（）中给出以下错误：方法：

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.remote.service.DriverService.findExecutable(DriverService.java:124)
        at org.openqa.selenium.chrome.ChromeDriverService.access$000(ChromeDriverService.java:32)
        at org.openqa.selenium.chrome.ChromeDriverService$Builder.findDefaultExecutable(ChromeDriverService.java:137)
        at org.openqa.selenium.remote.service.DriverService$Builder.build(DriverService.java:339)
        at org.openqa.selenium.chrome.ChromeDriverService.createDefaultService(ChromeDriverService.java:88)
        at org.openqa.selenium.chrome.ChromeDriver.<init>(ChromeDriver.java:123)
        at Quickstart.main(Quickstart.java:130)

我试过寻找gradle + Maven + selenium支持的版本。无法找到任何好消息。任何的想法？

此错误消息...... 

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

...意味着 Java客户端无法找到ChromeDriver()。

问题＆amp;溶液

根据您共享的 Selenium - Java代码，System.setProperty()行用于设置 ChromeDriver 二进制路径而不是chrome二进制路径路径即可。为此，您必须从ChromeDriver - WebDriver for Chrome下载 ChromeDriver 二进制文件并将其放入系统中，并通过System.setProperty()提及 ChromeDriver 的绝对路径线。因此你必须改变：

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

致：

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

尝试将您的番石榴更新为

let html = arr.reduce((all, one) => all += one.toHTML(), '');

它将解决您的问题。

只想在这里发帖，以防其他人像我一样从Google那里找到它。无论出于什么原因，我都需要运行sudo。使用npm selenium-standalone软件包并运行时出现问题：

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

它将显示该错误。修复了使用sudo运行的问题

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

我认为我以前不需要这样做，但是突然之间，这是目前唯一的工作方式。

我遇到了同样的问题，进行了依赖性检查，发现存在冲突。对我有用的解决方案是排除冲突的依赖关系。

您的项目可能与我的项目有不同的依赖性。因此，列出我项目中的特定冲突可能没有帮助。

答案 5 :(得分：0)

仅添加以下内容是不够的

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>27.1-jre</version>
</dependency>

它首先没有工作。然后我在pom.xml中将此依赖关系上移了 比junit的依赖，它的工作原理。因此，请确保pom文件中的文件高于junit或testng或您使用的任何运行程序
