JGit and finding the Head

Question

I\'m trying to get my hands on the HEAD commit with JGit:

val builder = new FileRepositoryBuilder()
val repo = builder.setGitDir(new File(\"/www/test-repo\")         


        

Answer 1

For the completeness sake, here is a fully working example how to get the hash for the HEAD commit:

public String getHeadName(Repository repo) {
  String result = null;
  try {
    ObjectId id = repo.resolve(Constants.HEAD);
    result = id.getName();
  } catch (IOException e) {
    e.printStackTrace();
  }
  return result;
}
