Java 使用IKVM将JAR文件转换为.DLL时出现警告

我需要在我的asp.net应用程序中使用openForecast.jar，因为我在cmd中编写时到处阅读并找到了IKVM

ikvmc openForecast.jar

然后我收到了这样的警告信息

D:\Bobby\Telkom Project\ikvm-0.44.0.5\bin>ikvmc OpenForecast-0.4.0.jar

我还发现openForecast由大约6个类文件和3个子文件夹组成，每个子文件夹包含几个类文件。。

我需要帮助为什么会发生这种情况以及如何修复它（因为IKVM的文档本身仍然让我一无所获），谢谢你第一个提示：忽略警告并使用代码。Java JAR通常指的是除了您不关心的特定场景之外不使用的外部代码

另一种选择是找到org.jfree.data.time类应该来自何处，并获取该jar并将其链接（但您将冒着它也有一些悬而未决的依赖关系的风险）。

如何“链接它”？这些信息会很有帮助，因为我有一个jar，它在运行时调用丢失的类。-1用于忽略警告。我还没有见过一个Java开发人员不会“忽略警告”。警告的存在是有原因的。
