我想为JasperReport运行示例演示，所以我下载了该文件但是当我在Windows 7命令行according to the Jasperreport documentation中输入以下内容时：
C:\jasperreports-4.7.0\demo\samples\barbecue>ant run
我收到以下错误：
“烧烤”项目中不存在目标“运行”。
那么可能是什么问题？
::修订::
在我的CMD中输入ant –p后，我得到以下内容： -
C:\jasperreports-4.7.0\demo\samples\barbecue>ant -p
Buildfile: C:\jasperreports-4.7.0\demo\samples\barbecue\build.xml
Shows how barcodes could be included in reports using the Barbecue component.

Java错误就像车祸。一辆汽车撞到另一辆汽车，导致第一辆汽车照亮路灯。路灯翻倒并撞上一辆爆炸的汽油卡车。
最后，你有毁灭，火灾和死亡。然而，整个事情开始是因为司机太忙了发短信并且没有停在停车标志处。
你有一长串的错误信息，但最重要的是那些最重要的信息：
net.sf.jasperreports.engine.JRException: java.sql.SQLException: socket creation error
[java] at net.sf.jasperreports.engine.util.AbstractSampleApp.getDemoHsqldbConnection(AbstractSampleApp.java:158)
这是套接字创建错误。
此错误似乎指出您无法连接到服务器或数据库。
而且，这就是我可以得到的。我真的不认识贾斯帕，但我找到了this。这对你有帮助吗？
您应该运行服务器，还是需要连接到未创建的数据库？您是否有阻止连接到服务器/数据库的防火墙。 （我倾向于数据库问题，因为我确实在您的错误消息中看到了关于 hsqldb 和 sql 的内容。
我认为你不是Java开发人员，因为你似乎对Ant和它的 build.xml 文件感到困惑。有人可以帮助你吗？如果可以，请查看 build.xml 并查看目标 test 正在执行的操作。它正在运行Java命令，您可以尝试在Ant之外运行该命令。有时，这会给你更多信息。
答案 1 :(得分：2)
您应该运行 ant test 命令来运行示例（清理，编译和生成所有格式的报告：xls，pdf等）。
要查看 JRViewer 中的报告，您应该运行 ant view 命令。
ant test 的结果（输出）将为：

对net.sf.jasperreports.engine.JRException: java.sql.SQLException: sock
et creation error例外的反应：
您尝试启动的示例是使用与 HSQLDB 服务器的连接。要启动数据库，您应该从 ant runServer 文件夹中运行 demo/hsqldb 命令。
