找不到包导致编译失败
Fail to compile due to package not found
问题：在build.xml[=上使用“运行 As > Ant Build”构建失败17=]
当我尝试编译演示时java，它编译失败。附上build.xml和对应的eclipse设置。需要的包到位但仍然无法编译。
Here is the demo source code你也可以下载这个理财工具来玩玩。警告：涉及极高风险投资

使用命令行，以下命令可能有效：
ant rebuild
ant run

附带说明一下，IntelliJ 可能是 Eclipse 的一个很好的替代品，我个人更喜欢 IntelliJ。
