NO_CURRENT_BRANCH

NO_CURRENT_BRANCH

Error message

Could not determine current git branch.

What it means

With the fromBranch option, addTagDirect reads the current branch via git (e.g. rev-parse --abbrev-ref HEAD). If git returns an empty value (detached HEAD with no resolvable name, or a command failure) the function returns NO_CURRENT_BRANCH because it cannot derive the new tag name from the branch.

Solutions

1. Checkout a real branch first: 'git checkout -b feature-branch'
2. Create the tag explicitly with a name instead of using fromBranch
3. Verify 'git rev-parse --abbrev-ref HEAD' returns a branch name in the project root

Example fix

// before
add_tag({ tasksJsonPath: path, fromBranch: true }); // detached HEAD
// after
git checkout -b my-feature; add_tag({ tasksJsonPath: path, fromBranch: true });

const { execSync } = require('child_process');
function currentBranch(root) {
  try { return execSync('git rev-parse --abbrev-ref HEAD', { cwd: root }).toString().trim() || null; }
  catch { return null; }
}
if (args.fromBranch && !currentBranch(projectRoot)) { /* detached HEAD: pick explicit tag name */ }

function branchAvailable(args, root) {
  const b = args?.fromBranch ? currentBranch(root) : 'n/a';
  return !args?.fromBranch || (typeof b === 'string' && b.length > 0 && b !== 'HEAD');
}

const res = await addTagDirect(args);
if (!res.success && res.error?.code === 'NO_CURRENT_BRANCH') {
  // fall back to explicit name: addTagDirect({ ...args, fromBranch: false, name: 'my-tag' })
}

When it happens

Trigger: add_tag with fromBranch: true in a detached HEAD state, a bare repository, or when the git branch command fails/returns empty output.

Common situations: CI checkout of a specific commit SHA (detached HEAD); rebase in progress; repository with no commits yet; corrupted git state.
