JGit Check if a branch is checked out

Question

I am working on a project using JGit. I managed to delete a branch, but I also want to check if that branch is checked out or not. I found a variable in CheckoutCommand but it is private:

private boolean isCheckoutIndex() {
    return startCommit == null && startPoint == null;
}

No public method returns what I want. When I use the command below on a checked out branch it returns an error that the branch cannot be deleted, so I want to check first if is checked out or not.

git.branchDelete().setForce(true).setBranchNames(branchName).call();

Answer 1

Repository::getFullBranch() returns the full name (e.g. refs/heads/main) of the currently checked out branch, if any. Otherwise the ID of the HEAD commit is returned or null, if there is no commit.
