我自己找到了答案.从SWT 3.3开始,您不必再包含本机(DLL)库,因为它们位于jar本身中,并且只要调用SWT库就会解压缩它们.DLL文件从jar解压缩并放在"System.getProperty("user.home")"下的".swt"文件夹中.在我的情况下,问题是System.getProperty("user.home")被设置为"\ ubz01fst\Students\User2010\Com\xxx"这是一个UNC路径并且不可写(这通常发生在公司或组织中)电脑 ).

我不知道为什么计算机中的System.getProperty("user.home")取自Windows的环境变量"HOMESHARE"

解决方案包括使用可写路径更改System.getProperty("user.home"),例如:

System.setProperty("user.home", System.getenv("USERPROFILE"));

在调用任何SWT代码之前.
