Stanford CoreNLP-EGW4-REUT.512.找不到集群

Question

我正在使用CoreNLP包对用户评论做一些注释，自从我升级到3.5.0版本以来，我似乎反复遇到同样的错误：

我在这里搜索了几个类似的问题：

Stanford NER错误：加载distsim词典失败，Stanford NER tagger使用提供的模型生成“File not Found”异常，但这并没有解决我的问题：我只使用3.5.0中的代码和模型（通过Maven Central）。我尝试从NER模型修改props文件，并指向用户目录中的另一个。clusters文件，但没有成功（完全相同的错误）。

我用来实例化CoreNLP对象的代码也非常标准，但这里是：

    Properties props = new Properties();
    props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
    stan = new StanfordCoreNLP(props);

原来问题是Maven造成的。

我的代码位于一个实用程序库中，该库封装在Stanford CoreNLP之上，以提供额外的处理，并且它本身工作得非常好。但是，当将这个项目作为依赖项添加到我的主项目时，Maven默认将Stanford CoreNLP库模型的3.4版本导入主项目，这导致了上面描述的bug。
