java - 线程 "main"java.lang.NoClassDefFoundError : edu/stanford/nlp/pipeline/StanfordCoreNLP 中出现异常

Question

我从 https://stanfordnlp.github.io/CoreNLP/ 下载了 stanford corenlp zip 文件然后将其解压缩并插入其中。现在我尝试运行以下 java 文件。 javac -cp "*"SentimentAnalysis.java 工作正常，但 java SentimentAnalysis 抛出错误，线程“main”中的异常 java.lang.NoClassDefFoundError: edu/stanford/nlp/pipeline/StanfordCoreNLP。

import edu.stanford.nlp.pipeline.*;

导入java.util.*;

公共(public)类情感分析{

public static void main(String[] args) {

    // creates a StanfordCoreNLP object, with POS tagging, lemmatization, NER, parsing, and coreference resolution
    Properties props = new Properties();
    props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
    StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

    // read some text in the text variable
    String text = "Hello madam, this is a dam";

    // create an empty Annotation just with the given text
    Annotation document = new Annotation(text);

    // run all Annotators on this text
    pipeline.annotate(document);

}

}

错误如下

    Exception in thread "main" java.lang.NoClassDefFoundError: edu/stanford/nlp/pipeline/StanfordCoreNLP

使用以下步骤验证 jar

• 从http://jd.benow.ca/下载Java反编译器

• 通过下载的反编译器打开jar

• 验证所需的斯坦福CoreNLP 类是否存在

• 如果类(class)存在，请关注此帖子 how to run Java program including jar
