How to pull from origin using JGit on existing repository

I need a piece of code which can pull from origin and merge with local repo. I tried with local repo which can get the last commit and revision. however not able to pull the changes from origin.

File gitWorkDir = new File(gitDir);
Git git = Git.open(gitWorkDir);
Repository repo = git.getRepository();
UsernamePasswordCredentialsProvider user = new 
UsernamePasswordCredentialsProvider("username", "password");
PullCommand pullCmd = git.pull();
pullCmd.setCredentialsProvider(user);
pullCmd.call();
ObjectId lastCommitId = repo.resolve(Constants.HEAD);
log.info(lastCommitId);

where gitDir is my local Repository Dir.

You need to provide the remote repository name, and the remote branche name. For example origin and master:

PullResult result = git.pull()
    .setCredentialsProvider(user)
    .setRemote("origin")
    .setRemoteBranchName("master")
    .call();

if (result.isSuccessful()) {
  ...
} else {
  ...
}

Please also note that the result returned by the pull command is PullRequest—its method isSuccessful() indicates whether the pull was successful. You might want to add this logic in your code too.
