我的分析何所作的嘗試：
我的工程在開發環境下可以良好執行，但我想用ant進行打包就報編譯錯，錯誤如上。我看到所有的錯誤都與swt有關，所以我想應該是找不到swt的動態連線庫。但是我上網查過資料，試過若干種方法，如：
1、修改環境變數path，包含swt的dll檔案目錄；
2、把swt-awt-win32-3062.dll、swt-win32-3062.dll複製到c:\windows\system32目錄下；
3、直接執行java Frame -Djava.libarary.path=d:\\eclipse\\plugin\\org.eclipse.swt.win32_3.0.0\\os\\win32\\x86

等等……都沒有用。
我想可能是我的build.xml寫的有問題，誰能指教一下，謝謝！
