从类路径为 SUTime 初始化 JollyDayHoliday，ReflectionLoadingException：创建 TimeExpressionExtractorImpl 时出错

Question

我遇到了与 this 几乎相同的问题：

但是，就我而言，我正在使用 Clojure 构建 Web 应用程序，而我的同事正在使用 Java 构建我们的自然语言处理引擎。 NLP 作为一个 jar 包含在内。我们已经工作了几个星期，但我的同事添加了一些新的依赖项，这些依赖项现在给了我们这个错误。

这个人也报了类似的错误：

 Error creating edu.stanford.nlp.time.TimeExpressionExtractorImpl

参见here: with an answer here：

这两种情况的问题似乎是不同库的版本冲突，但我不知道如何解决这个问题。在 Clojure 应用程序中，我们使用 clj-time，它显然使用 Joda-Time 2.6，而 Stanford Core NLP 库似乎使用 Joda 2.1。有没有办法解决这个冲突？

两个软件都可以编译，Clojure 应用程序可以启动，包括 NLP 引擎。但是，Clojure 应用随后会调用 NLP 引擎中的 "start" 方法，这会导致 NLP 引擎加载它需要的词法分析器和解析器。然后我们得到这些消息和错误：

如果我在 Java 应用程序中执行此操作：

我看到了这个：

包括您的 project.clj 将有助于找到问题。您可能需要在 project.clj

的 :dependencies 部分使用 :exclusions 选项

来自https://github.com/technomancy/leiningen/blob/master/sample.project.clj

;;; Dependencies, Plugins, and Repositories
  ;; Dependencies are listed as [group-id/name version]; in addition
  ;; to keywords supported by Pomegranate, you can use :native-prefix
