请帮助我解决这种情况。我在 Java 中按照以下步骤操作，并将这个 jar 文件添加到 Robot 框架项目中。执行测试时，我收到 ClassNotFoundException。
Java 更正代码：
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import org.openqa.selenium.WebElement;
public class StoreElements{
public static final String ROBOT_LIBRARY_SCOPE = "GLOBAL";
public String storeTexts(List<WebElement> text){
for(WebElement theElement : text){
System.out.println("The Element class is:
"+theElement.getAttribute("class")+", text: " + theElement.getText());
}
return ((WebElement) text).getText();
}
}
机器人框架代码：
*** Settings ***
Library Selenium2Library
Library keywords.kcc.StoreElements
*** Keyword ***
Get the customer Names
@{customers} get webelements xpath=//div[contains(@class,'name-column')]
store Texts @{customers}
那是我需要在 Java 项目中包含 Selenium2Library 而不仅仅是 Selenium 或者是否有可能在 Java 中包含 Selenium2Library？
我收到的例外是，

根据 Kootstra 的建议，添加了 selenium-server-standalone-3.3.1 jar 文件，目前 RED.xml 如下所示，这次红线未显示在关键字“存储文本”下。只有在执行此操作时才会引发异常。而不是更长的异常消息。
控制台命令：

我创建了新项目，然后只将 'c:\jython2.7.0\selenium-server-standalone-3.3.1\' 与 Selenium2library 和自己的 java 库一起添加到类路径中。我还尝试在 jar 文件的末尾添加 .jar。它仍然有例外。但有一件事是现在它停止显示了;;.;
现在是控制台命令，
Command: C:\jython2.7.0\bin\jython.exe -J-Dpython.path=C:\jython2.7.0\Lib\site-packages -J-cp .;C:\Java\JarsKCC\GetElementList.jar;C:\jython2.7.0\selenium-server-standalone-3.3.1.jar -m robot.run -P C:\jython2.7.0\Lib\site-packages\Selenium2Library -i SmokeTest --listener C:\Users\CON_RT~1\AppData\Local\Temp\RobotTempDir9154227905398549031\TestRunnerAgent.py:54485:False -s KCC_Automation.TestSuites.TestResource -t KCC_Automation.TestSuites.TestResource.logon to kcc with valid credentials -t KCC_Automation.TestSuites.TestResource.navigate to customer's page -t KCC_Automation.TestSuites.TestResource.display customer names -t KCC_Automation.TestSuites.TestResource.stop testing C:\Java\Workspace\KCC_Automation

这次例外不同。ClassCastException：org.python.core.PyObjectDerived 不能转换为 org.openqa.selenium.WebElement
