我想为 JasperReport 运行示例演示，因此我下载了该文件，但是当我根据 Jasperreport 文档在 Windows 7 命令行中键入以下内容时：
C:\jasperreports-4.7.0\demo\samples\barbecue>ant run
我收到以下错误：
项目 "barbecue" 中不存在目标 "run" 。
那么可能是什么问题？
::更新::
在我输入ant –pCMD 后，我得到以下信息：-
C:\jasperreports-4.7.0\demo\samples\barbecue>ant -p
Buildfile: C:\jasperreports-4.7.0\demo\samples\barbecue\build.xml
