我已经在项目构建路径中导入了apache poi的所有jar文件，但是仍然收到错误“xssfworkbook类型的getsheetat（int）方法引用了缺少的xssfsheet类型”
im使用版本-poi-bin-4.1.2-20200217
代码：

ackage ReadExcelData;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class ReadExcel {

    /**
     * @param args
     * @throws Exception 
     */
    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub

        File src = new File("C:\\Users\\Vishwa\\Desktop\\DeskTop\\Projects\\Automation Projects\\TestData.xlsx");

        FileInputStream fis = new FileInputStream(src);

        XSSFWorkbook wb = new XSSFWorkbook(fis);

        wb.getSheetAt(0);  //Error here: The method getSheetAt(int) from the type XSSFWorkbook refers to 

                            the missing type XSSFSheet  ,  

  The type org.apache.poi.xssf.usermodel.XSSFSheet cannot be resolved. It is indirectly referenced from required .class files

    }
