tar-jackrabbit oak 的文件存储库错误

Question

几个月来我一直在与大野兔橡树一起工作。虽然使用 MongoDB 作为后端一切正常，但我在使用基于 tar 文件的 Segment NodeStore 时遇到了问题。

在这里，只使用 nt:folder 节点就像使用 MongoDB 一样，但是当我尝试处理文件 (nt:file) 时，我得到以下错误提示（将节点写入存储库时）：

这似乎是 guava 的问题。这是 oak 中的错误还是我的错？但是问题出在哪里呢？

您的类路径中很可能有多个/无效版本的 Guava。请检查 mvn dependency:tree 关于番石榴的打印内容。
