Where to add the path of head/ref/master in github

Question

I am using the jgit . I am new to it i am able to clone the code from github but when i tried to push code in java it is giving me error.

Here's code : public class PullFromRemoteRepository {

private static final String REMOTE_URL = "https://github.com/raghav1/local.git";

public static void main(String[] args) throws IOException, InvalidRemoteException, TransportException, GitAPIException {
    // prepare a new folder for the cloned repository
    File localPath = File.createTempFile("raghav345", "");
    localPath.delete();

    // then clone
    System.out.println("Cloning from " + REMOTE_URL + " to " + localPath);
    Git.cloneRepository()
            .setURI(REMOTE_URL)
            .setDirectory(localPath)
            .call();

    // now open the created repository
    FileRepositoryBuilder builder = new FileRepositoryBuilder();
    Repository repository = builder.setGitDir(localPath)
            .readEnvironment() // scan environment GIT_* variables
            .findGitDir() // scan up the file system tree
            .build();

    Git git = new Git(repository);
    git.pull()
            .call();

    System.out.println("Pulled from remote repository to local repository at " + repository.getDirectory());

    repository.close();
}

}

Errors are coming like this:

Exception in thread "main" org.eclipse.jgit.api.errors.NoHeadException: Pull on repository without HEAD currently not supported at org.eclipse.jgit.api.PullCommand.call(PullCommand.java:170) at org.dstadler.jgit.unfinished.PullFromRemoteRepository.main(PullFromRemoteRepository.java:61)

Can anybody help me where to set the path of head.

Thanks

The code after the comment 'now open the created repository' does not actually open the cloned repository. Thus the pull command acts on an empty repository.

Either re-use the Git instance that is returned from the CloneCommand or change your code to something like this:

Git git = Git.cloneRepository().setURI( REMOTE_URL ).setDirectory( new File( "local/path/to/repo" ) ).call();
File gitDir = git.getRepository().getDirectory();
git.close();
// ...
FileRepositoryBuilder builder = new FileRepositoryBuilder();
Repository repository = builder.setGitDir( gitDir ).setMustExist( true ).build();

When i am using your suggestion . It is giving me this error Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method setDirectory(File) in the type CloneCommand is not applicable for the arguments (String) – user3352615 Aug 15 '14 at 17:26
As the exception message says, you are running the snippet despite a compile error. Replace "local/path/to/repo" with a File that points to the directory where the cloned repository should go - same as you did in the snippet from the question. – Rüdiger Herrmann Aug 19 '14 at 11:07
