Question

我试图通过WebDriverBackedSelenium在iexplore中使用Selenium Webdriver运行Selenium RC的代码。

在SeleniumConfig.class中我有：

  File file = new File("C:/Selenium/IEDriverServer.exe");
   System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
   WebDriver driver = new InternetExplorerDriver();
   selenium = new WebDriverBackedSelenium(driver, "https:// my web ");

通常，SeleniumConfig for RC中的代码是

   selenium = new DefaultSelenium("localhost", getPuerto(),
                    "*iexplore", "https:// my web");
   selenium.start();

这是有效的。但是用新代码替换我得到了这个错误：

java.lang.NoClassDefFoundError: org/openqa/selenium/ExplodingSupplier
    at org.openqa.selenium.WebDriverCommandProcessor.<init>(WebDriverCommandProcessor.java:165)
    at org.openqa.selenium.WebDriverBackedSelenium.<init>(WebDriverBackedSelenium.java:30)
    at config.SeleniumConfig.start(SeleniumConfig.java:40)
    at idenLocaJava.LocaJavaSuite.setUp(LocaJavaSuite.java:18)
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at   .....

在控制台中：

Started InternetExplorerDriver server (32-bit)
2.45.0.0
Listening on port 12628
log4j:WARN No appenders could be found for logger (org.apache.http.client.protocol.RequestAddCookies).
log4j:WARN Please initialize the log4j system properly.

一些建议？可能我需要在POM.XML中有一些依赖？我有：

<dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
            <version>2.45.0</version>
            </dependency>
        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-server</artifactId>
            <version>2.45.0</version>
        </dependency>
        <dependency>

        <dependency>

            <artifactId>selenium-api</artifactId>
            <version>2.45.0</version>
        </dependency>  
         <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-exec</artifactId>
            <version>1.3</version>
        </dependency>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>16.0.1</version>
         </dependency>

我需要使用java 7，最新的兼容版本是selenium 2.46.0，我也试过。

感谢。

Answer 1

我期待这个问题通常是因为不同版本的罐子之间的罐子或冲突。因为Maven使用good来提供所需的依赖关系，可能只有selenium-java和selenium-server，当然还有一个用于htmlunit。提供了更多信息here

Answer 2

谢谢，我添加了

    <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-remote-driver</artifactId>
         <version>2.45.0</version>
    </dependency>
    <dependency>  
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-api</artifactId>
            <version>2.45.0</version>
    </dependency>   

    because without this I had
java.lang.NoClassDefFoundError: org/openqa/selenium/HasInputDevices

and 

<dependency>
        <groupId>com.google.guava</groupId>
        <artifactId>guava</artifactId>
        <version>16.0.1</version>
 </dependency>

becase whitout this i had

java.lang.NoClassDefFoundError: com/google/common/net/MediaType


I could delete 

<dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-exec</artifactId>
        <version>1.3</version>
    </dependency>

But still the error

Answer 3

看起来您的项目仍在引用旧的selenium jar。你可以在项目中运行“mvn dependency：tree”，看看你是否得到了正确的版本。尝试清洁和重建。

错误消息（WebDriverCommandProcessor和WebDriverBackedSelenium）中的selemium类来自旧的selenium包。在2.45.0中应该是：

com.thoughtworks.selenium.webdriven.WebDriverBackedSelenium
com.thoughtworks.selenium.webdriven.WebDriverCommandProcessor

noClassdefFoundError ExplodingSupplier
