jgit need 2 arguments error message

I am trying a simple java class to test the functionality of jGit (see below).

import org.eclipse.jgit.lib.Repository;
import org.eclipse.jgit.storage.file.FileRepositoryBuilder;

import java.io.File;
import java.io.IOException;


public class CreateRepository {
   public static void main( String[] args ){
       Repository myrepo = createRepository("/mypath");
   }
public static Repository createRepository(String repoPath) {

        FileRepositoryBuilder builder = new FileRepositoryBuilder();
        Repository repo = null;
        try {
            repo = builder.setGitDir(new File(repoPath))
              .readEnvironment() // scan environment GIT_* variables
              .findGitDir() // scan up the file system tree
              .build();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    return repo;
}
}

When i run this on Eclipse Indigo with latest jgit jar in my build path i get the error message "Need 2 arguments" - nothing else, no exceptions! :S

Thanks for any help in advance.

First look into package org.eclipse.jgit.api. The easiest start is from class Git:

// clone a repository
Git git = Git.cloneRepository().setURI("git://yourserver/repo.git").call();

// init a fresh new repository in the current directory
Git git = Git.init().call();

// open a repository on your disk
Git git = Git.open(new File("/path/of/repo");

Then explore the commands available on the git object you get from these starting points.

The only part of JGit which displays that error message is in the main() function of MyersDiff.

/** 
 * @param args two filenames specifying the contents to be diffed
 */
public static void main(String[] args) {
  if (args.length != 2) {
    System.err.println(JGitText.get().need2Arguments);
    System.exit(1);
  }
  // ...
}

So check your classpath and make sure your project (and your main()) are before the jgit.jar, and that you don't somehow calls the wrong main().
