java - Jackrabbit Oak 的 tar 文件存储库错误

Question

我已经用长耳兔橡树工作了几个月。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，仅使用 nt:folder 节点就像使用 MongoDB 一样工作，但是当我尝试处理文件 (nt:file) 时，我收到以下错误消息(将节点写入存储库时):

这似乎是 Guava 的问题..这是橡木中的错误还是我的错？但问题可能出在哪里呢？

Answer 1

很可能您的类路径中有多个/无效版本的 Guava。请检查关于 Guava mvn dependency:tree 打印的内容。
