警告使用IKVM

Question

我需要用openForecast.jar在我的asp.net應用程序的JAR文件轉換成.DLL，爲此，我在這裏和那裏閱讀，並發現IKVM，當我在cmd中

ikvmc openForecast.jar 

寫道：然後，我就警告訊息，這樣

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

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

我還發現，openForecast包括約6類文件和子文件夾3，每個包含幾個類文件.. 我需要幫助，爲什麼發生這種情況，以及如何解決它（因爲IKVM本身的文檔仍然讓我無處可尋），謝謝

第一條提示：只需忽略警告並使用代碼即可。通常Java jar是指除了您不關心的特定場景之外未使用的外部代碼。

另一種方法是找到org.jfree.data.time類應該來自哪裏，並獲取該jar並將其鏈接（但您會冒風險，它也有一些懸掛的依賴關係）。
