错误：找不到或加载主类ExcelReadWrite

Question

I have a class ExcelReadWrite that runs fine when I run it through eclipse.But when I try to run it from command line I need to set classpath of dependent classes.

set CLASSPATH=C:\Users\NICSI\.m2\repository\org\apache\poi\poi-ooxml\3.11\poi-ooxml-3.11.jar;C:\Users\NICSI\.m2\repository\org\apache\poi\poi\3.11\poi-3.11.jar;

After setting class path it compiles successfully but when I execute my class then this exception occurs.

Error: Could not find or load main class ExcelReadWrite

 public class ExcelReadWrite {

public static void main(String[] args) {
    String inputFile=args[0];
    String outputFile=args[1];
    System.out.println("inputFile 0   "+inputFile);
    System.out.println("outputFile 0   "+outputFile);
    transformExcelFile(inputFile,outputFile);
    //transformExcelFile("E:\\excel\\inputFile.xlsx","E:\\excel\\outputFile.xlsx");
    }
    }

I use following command to compile and execute my class

E:\excelTest>javac ExcelReadWrite.java

E:\excelTest>java ExcelReadWrite
Error: Could not find or load main class ExcelReadWrite

您必须将实际目录添加到您的类路径中：

E:\excelTest>java -cp .;%CLASSPATH% ExcelReadWrite
