Eclipse不会从.jrxml文件生成.jasper文件

Question

我已经从marketPlace安装了Jaspersoft Studio插件。我创建了一个java项目并将其转换为Maven以导入Jasper报告jar。之后我创建了一个Blank_A4.jrxml文件。因此，我在本教程中添加了一些java类

https://www.tutorialspoint.com/jasper_reports/jasper_filling_reports.htm

如下面的屏幕截图所示。

问题是当运行.jrxml文件时，还没有.jasper文件正在生成。有谁知道问题是什么？

我已更改此课程中sourceFileName的路径：

package com.tutorialspoint;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource;

public class JasperReportFill {
   @SuppressWarnings("unchecked")
   public static void main(String[] args) {
      String sourceFileName = 
            "C://Users/alex.tree/Documents/iReport Designer workspace/Blank_A4.jasper";

      DataBeanList DataBeanList = new DataBeanList();
      ArrayList<DataBean> dataList = DataBeanList.getDataBeanList();

      JRBeanCollectionDataSource beanColDataSource =
      new JRBeanCollectionDataSource(dataList);

      Map parameters = new HashMap();
      /**
       * Passing ReportTitle and Author as parameters
       */
      parameters.put("ReportTitle", "List of Contacts");
      parameters.put("Author", "Prepared By Manisha");

      try {
         JasperFillManager.fillReportToFile(
         sourceFileName, parameters, beanColDataSource);
      } catch (JRException e) {
         e.printStackTrace();
      }
   }
}
