我有同样的问题,但对我来说,从 Ant 1.8.1 升级到 1.9.4 解决了这个问题。
我的猜测是根本原因是错误 52754。
编辑:使用JDK 1.6.0_18,同样的问题以稍微不同的形式重新出现,堆栈跟踪如下:

有趣的是,该错误只发生在 Windows 上,而且只是偶尔发生,可能七次左右出现一次。
该错误源于Apache Resolver 库中类的normalize
函数。PublicId
normal.indexOf(" ")
有时会返回错误的值。例如,如果输入字符串是-//OASIS//ELEMENTS DITA 1.x Programming Domain//EN
,则pos
变量将50
作为其值,即使公共 ID 字符串没有任何额外的空格。
这使我认为根本原因可能与JDK 错误 #6967156 有关,但我完全不能确定,因为在我们的案例中,错误是间歇性的,但错误报告中没有任何迹象表明这一点。
