How to fix fatal: invalid reference: feature in Git

# List all local branches
git branch

# List all branches including remote tracking branches
git branch -a

# Check if Git can resolve the reference
git rev-parse feature

# Fetch all branches from origin
git fetch origin

# Or fetch a specific branch
git fetch origin feature:feature

# Configure fetch to get all branches
git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/*"

# Fetch all branches
git fetch --all

# If you have a shallow clone, unshallow it
git fetch --unshallow

# Create worktree with a new branch tracking origin/feature
git worktree add -b feature ../feature-worktree origin/feature

# Or if you want the worktree directory named after the branch
git worktree add -b feature ./feature origin/feature

# Create a worktree with detached HEAD at the remote branch
git worktree add --detach ../feature-worktree origin/feature

// In Jenkinsfile
checkout([
    $class: 'GitSCM',
    branches: [[name: '*/main']],
    extensions: [[$class: 'CloneOption', shallow: false]],
    userRemoteConfigs: [[url: 'https://github.com/user/repo.git']]
])

# In .gitlab-ci.yml
variables:
  GIT_DEPTH: 0  # Disable shallow cloning
  GIT_STRATEGY: fetch

# In workflow file
- uses: actions/checkout@v4
  with:
    fetch-depth: 0  # Fetch all history

# List current worktrees
git worktree list

# Prune stale worktree information
git worktree prune

# Verify the worktree list is clean
git worktree list

# See what HEAD points to
git symbolic-ref HEAD

# If HEAD points to refs/heads/feature and you want a worktree for feature:
# Option 1: Change HEAD to a different branch first
git symbolic-ref HEAD refs/heads/main

# Option 2: Use a commit hash instead of branch name
git worktree add ../feature-worktree $(git rev-parse feature)

# Branch with spaces (not recommended but possible)
git worktree add "../my worktree" "feature/my branch"

# Branch with slashes (common in Git Flow)
git worktree add ../hotfix-worktree feature/hotfix-123
