class not find

[hbthien]

Hi all,

I tried to test the LSA class. From the instruction of Getting Started wiki page, I run the command from the S-Space directory:
user@machine$ java -cp classes edu.ucla.sspace.mains.LSAMain

But I received an error:
Error: Could not find or load main class edu.ucla.sspace.mains.LSAMain

In addition, when I run the LSAMain.java, I got this:

Even it produces an output file, it has an error
Exception in thread "WorkerThread-1" java.util.NoSuchElementException

Could you please tell me how to fix this error?
Thank you.

Hi, you can go to the "target " folder and rerun "java -cp classes edu.ucla.sspace.mains.LSAMain"

[niveditakatakam]

same problem as that of hbthein but the target file is not created !!

[davidjurgens]

Did you run "mvn compile" or "mvn package" first to get all the code
compiled? One of those two steps is necessary for the target directory to
be created.

Thanks,
David

hey David,

where to give that command ?? and is it necessary to create any environment variable

thank you

[davidjurgens]

You need to run that from the command line in the directory where you
cloned the github repository.

You might also be able import the maven pom.xml into an environment like
Netbeans or Eclipse, which can build the classes. However, I have never
tried this and am not sure how it works.
