Question

我在Ubuntu 14.04上使用Stanford CoreNLP，当我运行以下代码时遇到以下问题：

Java代码：

package com.mycompany.app;

import java.io.*; 
import java.util.*;

/*import edu.stanford.nlp.ling.HasWord;
import edu.stanford.nlp.ling.TaggedWord;
import edu.stanford.nlp.parser.shiftreduce.ShiftReduceParser;
import edu.stanford.nlp.process.DocumentPreprocessor;
import edu.stanford.nlp.parser.lexparser.ExhaustivePCFGParser;
import edu.stanford.nlp.trees.Tree;*/

import edu.stanford.nlp.tagger.maxent.MaxentTagger;

public class App
{   
    public static void main(String[] args) throws Exception, NoClassDefFoundError
    {
        MaxentTagger tagger = null;
        if(tagger == null)
        {
            tagger = new MaxentTagger("mymodel.tagger");
        }
        System.out.println("Let's do this!");
    }
}

命令运行

mvn clean install exec：java -Dexec.mainClass = com.mycompany.app.App

终端输出：

的pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

      <version>3.5.2</version>
    </dependency>
  </dependencies>
</project>

但是，将pom.xml中的版本从3.5.2更改为1.3.0可以正常工作。这可能是什么原因？

谢谢！

P.S。 如果它有用，maven项目是由以下命令创建的：

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=dt_mvn -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

pom.xml中的Stanford CoreNLP版本更改导致错误
