得分: 1

使用命令行，以下命令可能有效：

  1. ant rebuild
  2. ant run

从路径 C:\Program Files\CandleWorks\ForexConnectAPI\samples\java\NonTableManagerSamples\Login&gt; 或等效路径运行。

另外，值得一提的是，IntelliJ 可能是 Eclipse 的一个不错替代品，我个人更喜欢 IntelliJ。

英文:

Using the command line, the following commands might work:

  1. ant rebuild
  2. ant run

from the path C:\Program Files\CandleWorks\ForexConnectAPI\samples\java\NonTableManagerSamples\Login&gt; or equivalent.

As a side-note, IntelliJ may be a good alternative to Eclipse, I prefer IntelliJ myself personally.
