Push to GitLab with JGit authorization error

I am able to clone from GitLab via JGit, but when I go to push the changes, I get a not authorized error message.

Three more essential details:

  1. I own the repository so it's not an issue with read-only access.

  2. The repository is private so I know the OAuth 2 token is valid and being used in the initial clone.

  3. I ONLY have the username and an oauth2 token. I do not have the user's password, SSH key, or personal access token.

Here is my command for cloning: 

Git.cloneRepository()
  .setURI(target)
  .setDirectory(repoFolder)
  .setCloneAllBranches(true)
  .setCredentialsProvider(new UsernamePasswordCredentialsProvider("oauth2", token))
  .call();

Here is my command for pushing:

PushCommand push = cloneSource.push();
  push.setRemote(target);
  push.setPushAll();
  push.setCredentialsProvider(new UsernamePasswordCredentialsProvider("oauth2", token));
  push.call();

I am using Git.lsRemoteRepository() method from JGit using OAuth2 access token.

Setting UsernamePasswordCredentialsProvider like this actually worked for me:

    LsRemoteCommand cmd = Git.lsRemoteRepository();
    cmd.setRemote(cloneUrl);
    cmd.setCredentialsProvider(new UsernamePasswordCredentialsProvider("oauth2", gitlab-access-token));

The url is of a private Gitlab repository- https://gitlab.com/my-private-group/testprojectxyxy.git

For authenticating gitlab using personal access token and jgit, you can use the following snippet:

With the snippet below, I was able to push back to a GitLab repository.

CredentialsProvider credentialsProvider = new 
     UsernamePasswordCredentialsProvider( "PRIVATE-TOKEN", <your oauth token> );
git.push()
     .setCredentialsProvider( credentialsProvider )
     .call();

This works as of Jgit version (4.8.0.201706111038-r)

With the snippet below, I was able to clone from and push back to a GitLab repository.

CredentialsProvider credentialsProvider 
  = new UsernamePasswordCredentialsProvider( "myname", "password" );
Git git = Git.cloneRepository()
  .setURI( "https://gitlab.com/myname/repo.git" )
  .setDirectory( tempFolder.newFolder() )
  .setCredentialsProvider( credentialsProvider )
  .call();

File file = new File( git.getRepository().getWorkTree(), "file" + new Object().hashCode() );
file.createNewFile();
git.add().addFilepattern( file.getName() ).call();
git.commit().setMessage( "Add file " + file.getName() ).call();

git.push()
  .setCredentialsProvider( credentialsProvider )
  .call();

If you are using GitLab's Personal Access Tokens, you need to encode the access token into the URL and provide it as a password, like this:

CredentialsProvider credentialsProvider 
  = new UsernamePasswordCredentialsProvider( "myname", "<token>" );
command.setURI( "https://gitlab-ci-token:<token>@gitlab.com/myname/repo.git" )
command.setCredentialsProvider( credentialsProvider )

Maybe that will help to find the source of the 'not authorized' error. In order to communicate through SSH, you need to add an SSH key to your GitLab profile.
