警告使用IKVM

Question

我需要用openForecast.jar在我的asp.net应用程序的JAR文件转换成.DLL，为此，我在这里和那里阅读，并发现IKVM，当我在cmd中

ikvmc openForecast.jar 

写道：然后，我就警告讯息，这样

D:\Bobby\Telkom Project\ikvm-0.44.0.5\bin>ikvmc OpenForecast-0.4.0.jar 
Note IKVMC0002: output file is "OpenForecast-0.4.0.dll" 
Warning IKVMC0100: class "org.jfree.data.time.TimeSeries" not found 
Warning IKVMC0100: class "org.jfree.data.time.RegularTimePeriod" not found 
Warning IKVMC0100: class "org.jfree.data.time.TimeSeriesDataItem" not found

Warning IKVMC0111: emitted java.lang.NoClassDefFoundError in "net.sourceforge.op

enforecast.output.TimeSeriesOutputter.output(Lnet.sourceforge.openforecast.DataP 
oint;Ljava.lang.String;)V" 
("org.jfree.data.time.TimeSeriesDataItem") 

我还发现，openForecast包括约6类文件和子文件夹3，每个包含几个类文件.. 我需要帮助，为什么发生这种情况，以及如何解决它（因为IKVM本身的文档仍然让我无处可寻），谢谢

第一条提示：只需忽略警告并使用代码即可。通常Java jar是指除了您不关心的特定场景之外未使用的外部代码。

另一种方法是找到org.jfree.data.time类应该来自哪里，并获取该jar并将其链接（但您会冒风险，它也有一些悬挂的依赖关系）。
