Error using Stanford CoreNLP in command line

Question

I am new to working with programs written in Java and am having a whole lot of trouble getting StanfordCoreNLP to do what it's supposed to do. I unzipped the program into its own directory, to which I added the XML file the program is supposed to process. The code I've been using to process the file in command line is:

java -cp stanford-corenlp-YYYY-MM-DD.jar:stanford-corenlp-YYYY-MM-DD-models.jar:xom.jar:joda-time.jar -Xmx3g edu.stanford.nlp.pipeline.StanfordCoreNLP [ -props ] -file .

The problem is that every time I try to run this I get the following error: "could not find or load main class edu.stanford.nlp.pipeline.StanfordCoreNLP." I'm just not sure how to deal with this error and would appreciate any help anyone can give. Thanks.

The command is correct are you sure you're running it from the correct directory? That error seems as if you're either in the wrong directory or you've got a corrupted zip file. — cjds

In command line I'm running it from the directory I put it in when i downloaded it. How would I know if I had a corrupted zip file? — Saul

Are you sure it's called stanford-corenlp-YYYY-MM-DD.jar? I would think they'd give the year-month-date of the build. — hd1

@hd1 LOL Yeah.. I'm assuming you replaced YYYY-MM-DD with the year month and date of your build. There's no real way to know if the ZIP file is corrupted. The only way is to re-download and see if it was messed up in the first place. — cjds

Are you using Windows? Have you checked the line below that reads

"For Windows, the colons (:) separating the jar files need to be semi-colons (;)."

Using the example, as is, will give you that error.

You have to install Java 1.8 to be able to run this command.

Running the following commands will install Java 1.8:

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer

This is taken directly from http://tecadmin.net/install-oracle-java-8-jdk-8-ubuntu-via-ppa/; for more information you can use that page.

Most probably, jar files in Stanford CoreNLP folder are named on versions such as Stanford-corenlp-3.4.1.jar in case of 2014-08-27 build. Either rename the file names as Stanford-corenlp-3.4.1.jar in command or rename the files in folder such as Stanford-corenlp-YYYY-MM-DD.jar.
