Cannot instantiate a StanfordCoreNLP pipeline in a Springboot Project using Maven
Author: clxxiiiCreated May 24, 2024Updated Jun 24, 2024
I made a super simple example maven project, that has two dependencies: stanford-corenlp and spring-boot-starter-web, and got the pom.xml trimmed down as much as I know how.

</project>My example project only has one file, an App.java with a main class which only makes a StanfordCoreNLP pipeline.
package com.test;
import edu.stanford.nlp.pipeline.StanfordCoreNLP;
import java.util.Properties;
public class App {
public static void main( String[] args ) {
Properties props = new Properties();
props.setProperty("annotators", "tokenize,pos,lemma,ner,depparse");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
}
}Running this main function results in the following error:
