我是Selenium的新手，在从命令提示符（通过框架）运行我的selenium Java文件时遇到了问题。
我有两个Java（Selenium）文件：1。ShoppingCart.java（具有所有功能和主要方法），2。ExcelWrite.java（具有Excel对象并处理Excel工作表以更新结果）
我将ExcelWrite.java的静态方法调用到我的主类ShoppingCart.java中：
＆LT;＆LT; ExcelWrite.method_name（argument_list）＆gt;＆gt;
这两个文件属于同一个包＆＃34; shop＆＃34;。
当E尝试按javac ExcelWrite.java和javac ShoppingCart.java分别编译上述两个文件时，ExcelWrite.java会编译，但ShoppingCart.java会出错：
在＆lt;＆lt;＆lt; ExcelWrite.method_name（argument_list）＆gt;＆gt;
然而，当我尝试这个时：javac *.java（来自文件所在的目录），两个文件都会编译，而.class文件会被创建。
但是当尝试从命令提示符运行ShoppingCart.java时，它会给我错误：
无法找到或加载主类。
脚本在Eclipse上完美运行。
java版本：1.8.0_25
环境变量中jdk的路径：C:\Program Files\Java\jdk1.8.0_25\bin;
我的java文件的路径：C:\Users\pooja.a.tripathi\Desktop\Omni
环境变量中的类路径：C:\Program Files\Java\jdk1.8.0_25\bin;C:\Dependency\selenium-java-2.40.0.jar;C:\Dependency\selenium-server-standalone-2.40.0.jar;C:\Dependency\Eclipse_TestNG\guava-base-r03.jar;C:\Dependency\Eclipse_TestNG\guava-collections-r03.jar;C:\Dependency\Eclipse_TestNG\junit-4.8.2.jar;C:\Dependency\Eclipse_TestNG\testng.jar;C:\Dependency\Eclipse_TestNG\testng-sorces.jar;C:\Dependency\POI\commons-codec-1.5.jar;C:\Dependency\POI\commons-logging-1.1,jar;C:\Dependency\POI\dom4j-1.6.1.jar\C:\Dependency\POI\junit-4.11.jar;C:\Dependency\POI\log4j-1.2.13.jar;C:\Dependency\POI\poi-examples-3.10-FINAL-20140208;C:\Dependency\POI\poi-excelant-3.10-FINAL-20140208.jar;C:\Dependency\POI\poi-ooxml-3.10-FINAL-20140208.jar;C:\Dependency\POI\poi-ooxml-schemas-3.10-FINAL-20140208.jar;C:\Dependency\POI\poi-scratchpad-3.10-FINAL-20140208;C:\Dependency\POI\stax-api-1.0.1.jar;C:\Dependency\POI\xmlbeans-2.3.0;C:\Dependency\POI\poi-3.10-FINAL-20140208.jar
我也尝试过设置classpath并使用：java -cp shop.ShoppingCart
java -cp .ShoppingCart但似乎没有任何效果。我尝试了各种线程上的所有可用但无济于事。我读到这个问题主要是由于classpath。
任何人都可以让我知道为什么我的两个Java文件都没有单独编译以及如何运行它？
以下是两个文件的代码：

答案 0 :(得分：0)
添加。到环境变量中的CLASSPATH变量解决了我的问题！
如果不添加，Java将在CLASSPATH变量中提到的路径中搜索类。在那里，它不会在当前工作目录中搜索类！
转到控制面板>系统和安全>系统>高级系统设置>高级
点击环境变量
如果CLASSPATH变量位于用户变量下，请添加“。”。用分号分隔。例如，如果将Java安装在C：\ Program Files \ Java \ jdk1.8.0_25 \ bin中，则CLASSPATH将为
C:\Program Files\Java\jdk1.8.0_25\bin;.;
单击确定。
