    }

}

这是斯坦福网站的示例，我试图从文件中读取内容，但在调用 StanfordCoreNLP (props) 构造函数的行处出现以下异常：

线程“main”中的异常

java.lang.NoSuchMethodError: edu.stanford.nlp.util.Generics.newHashMap()Ljava/util/Map；在 edu.stanford.nlp.pipeline.AnnotatorPool.(AnnotatorPool.java:27) 在 edu.stanford.nlp.pipeline.StanfordCoreNLP.getDefaultAnnotatorPool（StanfordCoreNLP.java:303） 在 edu.stanford.nlp.pipeline.StanfordCoreNLP.construct（StanfordCoreNLP.java:256） 在 edu.stanford.nlp.pipeline.StanfordCoreNLP.(S​​tanfordCoreNLP.java:129) 在 edu.stanford.nlp.pipeline.StanfordCoreNLP.(S​​tanfordCoreNLP.java:125) 在 Stanforder.main(Stanforder.java:35)

感谢任何帮助。谢谢！

参考第9题

http://nlp.stanford.edu/software/corenlp-faq.shtml#nosuchmethoderror

它说，

“这是因为你还拥有一个或多个斯坦福 NLP 的旧版本 类路径中的工具"

也可以看看，

https://mailman.stanford.edu/pipermail/java-nlp-user/2013-November/004357.html

上面写着，

显然有一些 jar 文件不兼容。你有没有老的 您的类路径中的我们工具的版本？
