由于ant中的内置缺失，jrxml文件编译失败

Question

ant脚本在编译.jrxml到.jasper文件时抛出错误，仅针对使用JasperReports内置函数的文件。请帮我解决这个问题。

JasperReports版本是5.5.2。我已经用

更新了jasperreports_extension.properties

net.sf.jasperreports.extension.registry.factory.functions=net.sf.jasperreports.functions.FunctionsRegistryFactory
net.sf.jasperreports.extension.functions.datetime=net.sf.jasperreports.functions.standard.DateTimeFunctions
net.sf.jasperreports.extension.functions.math=net.sf.jasperreports.functions.standard.MathFunctions, net.sf.jasperreports.functions.standard.LogicalFunctions
net.sf.jasperreports.extension.functions.text=net.sf.jasperreports.functions.standard.TextFunctions 

ant构建脚本中的错误跟踪:

Answer 1

jasperreport 5.5.3项目构建没有在dist目录下生成jasper-functions-5.5.2.jar。我们需要使用joda-time jar作为依赖项手动下载jasper-functions jar。
