由于找不到包，所以无法编译
由于找不到包，所以无法编译

Problem：在build.xml上使用"Run As > Ant Build“进行编译失败
当我试图编译一个演示java时，它无法编译。附加与build.xml和相应的eclipse设置。必需的包已就位，但仍未能编译。
下面是演示源代码你也可以下载这个金融工具来获得乐趣。警告:涉及非常高风险的投资

使用命令行，以下命令可能有效：
ant rebuild
ant run从路径C:\Program Files\CandleWorks\ForexConnectAPI\samples\java\NonTableManagerSamples\Login>或等效。
顺便提一句，IntelliJ可能是Eclipse的一个很好的替代方案，我个人更喜欢IntelliJ。
