前置依赖

本 skill 仅覆盖 worktree 生命周期管理(初始化、创建、删除 worktree)。 所有通用 Git 操作(commit、sync、rebase、历史搜索)由 nop-git-master skill 处理。

当用户请求涉及 worktree 内的通用 git 操作时,应同时加载 nop-git-master。

职责边界

操作归属 skill

重要提示

⚠️ 必须遵守的操作规则

  1. 所有 git worktree 相关命令必须在 .bare 目录中执行

    • ✅ 正确:git -C .bare worktree add ../feature-xxx -b feature-xxx
    • ❌ 错误:git -C .bare worktree add feature-xxx -b feature-xxx
  2. 创建 worktree 时使用相对路径

    • ✅ 正确:使用相对路径 ../
    • ❌ 错误:使用绝对路径
  3. 遇到错误时,按顺序清理

    cd ~/app/nop-entropy-wt
    git -C .bare worktree remove ../nop-entropy-feature-xxx 2>/dev/null || true
    rm -rf nop-entropy-feature-xxx 2>/dev/null || true
    git -C .bare worktree prune
    git -C .bare branch -D feature-xxx
    
  4. 操作目录

目录结构

project-root/                          # 项目根目录(如 ~/app/nop-entropy-wt)
├── .bare/                            # Git bare 仓库(中心),所有 git worktree 操作在此执行

命名规则:worktree 目录名 = <PROJECT_NAME>-<BRANCH_NAME>,便于在 IDE 中区分。


操作:初始化 bare + worktree 项目结构

参数:

  • 项目根目录 (必填): 如 ~/app/nop-entropy-wt
  • 远程仓库 URL (可选): 如 https://gitee.com/user/repo.git
  • 本地仓库路径 (可选): 现有 git 仓库的路径
cd ~/app/nop-entropy-wt

# 1. 创建 bare 仓库
git clone --bare https://gitee.com/canonical-entropy/nop-entropy.git .bare
# 或从本地克隆: git clone --bare ~/app/nop-entropy .bare

# 2. 启用长路径支持(Windows 平台重要配置)
git -C .bare config core.longpaths true

# 3. 识别项目名称(从 remote URL 提取)
PROJECT_NAME=$(git -C .bare config --get remote.origin.url | sed -E 's|.*/([^/]+?)(\.git)?$|\1|')

# 4. 识别默认分支
DEFAULT_BRANCH=$(cat .bare/HEAD 2>/dev/null | sed 's@^refs/heads/@@')
if [ -z "$DEFAULT_BRANCH" ]; then
    DEFAULT_BRANCH=$(git -C .bare symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')
fi

# 5. 创建主分支 worktree(目录名: PROJECT_NAME-BRANCH_NAME)
git -C .bare worktree add "../${PROJECT_NAME}-${DEFAULT_BRANCH}" "$DEFAULT_BRANCH"

# 6. 验证
git -C .bare worktree list

操作:创建新的 feature worktree

参数:

  • 需求描述 (必填): 自然语言描述的功能需求
  • 项目根目录 (必填): 如 ~/app/nop-entropy-wt

分支名生成规则:

需求类型前缀示例
新功能add-, feat-add-user-auth, feat-payment
修复fix-fix-login-error, fix-crash
重构refactor-refactor-db, refactor-job-scheduling
性能优化perf-, optimize-perf-query, optimize-cache
紧急修复hotfix-hotfix-security
文档docs-docs-api
测试/杂项test-, chore-test-auth, chore-deps
cd ~/app/nop-entropy-wt

PROJECT_NAME=$(git -C .bare config --get remote.origin.url | sed -E 's|.*/([^/]+?)(\.git)?$|\1|')

BRANCH_NAME="refactor-job-scheduling"
WORKTREE_NAME="${PROJECT_NAME}-${BRANCH_NAME}"

# 1. 如果分支已存在,先清理
if git -C .bare branch --list "$BRANCH_NAME" > /dev/null; then
    git -C .bare worktree remove "../$WORKTREE_NAME" 2>/dev/null || true
    rm -rf "$WORKTREE_NAME" 2>/dev/null || true
    git -C .bare worktree prune
    git -C .bare branch -D "$BRANCH_NAME"
fi

# 2. 创建 worktree
git -C .bare worktree add "../$WORKTREE_NAME" -b "$BRANCH_NAME"

# 3. 创建 Maven 配置(Feature 分支专用)
mkdir -p "$WORKTREE_NAME/.mvn"
WORKTREE_ABS_PATH="$(cd "$WORKTREE_NAME" && pwd)"
cat > "$WORKTREE_NAME/.mvn/maven.config" <<EOF
-Dmaven.repo.local.head=$WORKTREE_ABS_PATH/.nop/repository
-Dmaven.repo.local.tail.ignoreAvailability=true
EOF

# 4. 验证
git -C .bare worktree list

操作:合并 Feature 分支回主分支

当 feature 分支开发完成后,将提交合并回主分支。

⚠️ 本流程步骤 1 和 4 需要 nop-git-master skill 已加载。

前置:本流程假设 feature 分支有多个中间提交,需要软重置后重新组织提交。

PROJECT_NAME="nop-entropy"

# 检测默认分支名(与 nop-git-master ENVIRONMENT DETECTION 一致)
DEFAULT_BRANCH=$(git -C ../.bare symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')
if [ -z "$DEFAULT_BRANCH" ]; then
  DEFAULT_BRANCH=$(git rev-parse --verify main 2>/dev/null && echo main || echo master)
fi

# 1. 更新主分支到最新
#    ⚠️ 使用 nop-git-master SYNC MODE 完整流程(ls-remote 检查 + refspec fetch + pull --ff-only)
#    不要在此内嵌简化版 SYNC 命令
cd ~/app/nop-entropy-wt/${PROJECT_NAME}-${DEFAULT_BRANCH}
# → 执行 nop-git-master SYNC MODE

# 2. 软重置 feature 分支到主分支(保留所有修改,撤销提交历史)
cd ../${PROJECT_NAME}-feat-xxx
git reset --soft "$DEFAULT_BRANCH"

# 3. 查看修改内容
git diff --cached --stat

# 4. 按 nop-git-master COMMIT MODE 生成提交信息并提交
# → 执行 nop-git-master COMMIT MODE

# 5. 合并到主分支
cd ../${PROJECT_NAME}-${DEFAULT_BRANCH}
git merge feat-xxx --ff-only

# 6. 同步主分支最新内容回 feature 分支
#    ⚠️ 使用 nop-git-master REBASE MODE 完整流程(安全评估 + refspec fetch + rebase)
cd ../${PROJECT_NAME}-feat-xxx
# → 执行 nop-git-master REBASE MODE(rebase onto)

操作:删除 feature worktree

⚠️ 删除前必须检查是否有未保存的工作:

cd ~/app/nop-entropy-wt

PROJECT_NAME=$(git -C .bare config --get remote.origin.url | sed -E 's|.*/([^/]+?)(\.git)?$|\1|')
BRANCH_NAME="feat-xxx"
WORKTREE_NAME="${PROJECT_NAME}-${BRANCH_NAME}"

# 1. 安全检查:确认没有未保存的工作
cd "$WORKTREE_NAME"
UNCOMMITTED=$(git status --porcelain 2>/dev/null)
UNPUSHED=$(git log --oneline "origin/$BRANCH_NAME..HEAD" 2>/dev/null)
if [ -n "$UNCOMMITTED" ] || [ -n "$UNPUSHED" ]; then
  echo "⚠️ 工作树有未保存/未推送的更改:"
  [ -n "$UNCOMMITTED" ] && echo "  未提交: $(echo "$UNCOMMITTED" | wc -l) 个文件"
  [ -n "$UNPUSHED" ] && echo "  未推送: $(echo "$UNPUSHED" | head -5)"
  echo "请先处理后再删除。如确认丢弃,请明确告知。"
  exit 1
fi
cd ..

# 2. 删除 worktree
git -C .bare worktree remove "../$WORKTREE_NAME" 2>/dev/null || true

# 3. 清理目录和引用
rm -rf "$WORKTREE_NAME" 2>/dev/null || true
git -C .bare worktree prune

# 4. 删除分支
git -C .bare branch -D "$BRANCH_NAME"

Maven 配置说明

分支类型Maven 配置说明
主分支 (main/master)不配置使用系统默认仓库(~/.m2/repository)
Feature 分支配置 .mvn/maven.config使用独立局部仓库(.nop/repository),避免依赖冲突
# Feature 分支 Maven 配置
WORKTREE_ABS_PATH="$(cd "nop-entropy-feat-auth" && pwd)"
cat > "nop-entropy-feat-auth/.mvn/maven.config" <<EOF
-Dmaven.repo.local.head=$WORKTREE_ABS_PATH/.nop/repository
-Dmaven.repo.local.tail.ignoreAvailability=true
EOF
