我有一个在 eclipse 中构建的项目，依赖于第 3 方 jar。我正在尝试为 ant 生成一个合适的构建文件 - 使用 Eclipses 内置的导出->ant 构建文件功能作为起始块。
当我运行构建目标时，出现以下错误：
[javac] error: error reading /base/repo/FabTrace/lib/apache/geronimo/specs/geronimo-j2ee-management_1.0_spec/1.0/geronimo-j2ee-management_1.0_spec-1.0.jar; error in opening zip file
整个构建文件（由 eclipse 自动生成）如下所示：
（注意：上面的错误总是引用类路径中列出的第一个 jar）

（我知道这里有 Eclipse 特定的东西。但是无论有没有它我都会得到相同的结果。）
我已经完成了旧的谷歌搜索并四处搜寻但没有成功。
我可以确认所有罐子确实存在。我也尝试过从命令行和 sudo - 再次得到相同的结果。
任何帮助将不胜感激。
Cheers
根据马丁·克莱顿的建议，我之前的评论复制如下作为答案。
“唉。我想是因为我删除了最初导致这个问题的第一个罐子（我什至不相信我真的需要它们了）并且问题只是转移到了下一个罐子......好吧，那个让我怀疑系统错误。事实证明，我的类路径上确实有很多垃圾罐。一定是在某个时候搞砸了下载或其他东西。无论如何，现在全部修复了。干杯”
