cloneRepository static method

Future<void> cloneRepository(String url, String pathRep, { String branch = 'master', })

克隆Git仓库到指定位置

TODO 待完善逻辑以及测试

执行逻辑：

1. 判断当前路径中是否为git仓库，如果不是则进行克隆，如果是则判断是否有变动文件，如果有则暂存，然后更新仓库所有文件
2. 判断需求分支在远程是否存在，如果存在则检出，如果不存在则以master分支为基准进行创建

url 仓库URL pathRep 需要克隆地址 branch 克隆分支

Implementation

static Future<void> cloneRepository(
  String url,
  String pathRep, {
  String branch = 'master',
}) async {
  // 远程分支分支
  List<String> remoteBranchList = [];
  // 是否包含当前分支
  bool hasBranch;

  final existsPath = await IOUtil.existsAsync(pathRep);
  final existsRepo = existsPath &&
      (await IOUtil.existsAsync(PathUtil.join(pathRep, '.git')));

  if (existsPath && existsRepo) {
    // 如果有变更文件则执行暂存
    if (await checkHasChange(pathRep)) {
      stashChanges(pathRep);
    }
    remoteBranchList = await getRemoteBranchList(pathRep);
    hasBranch = remoteBranchList.contains(branch);
    // 更新所有分支代码
    for (final remoteBranch in remoteBranchList) {
      final cmdCheckout = 'git checkout $remoteBranch';
      // 如果有变更文件则执行暂存
      if (await checkHasChange(pathRep)) {
        stashChanges(pathRep);
      }
      await ProcessUtil.runCmdWait(
        cmd: cmdCheckout,
        workingDirectory: pathRep,
      );
      final cmdPull = 'git pull origin $remoteBranch';
      await ProcessUtil.runCmdWait(
        cmd: cmdPull,
        workingDirectory: pathRep,
      );
    }
  } else {
    if (existsPath) {
      IOUtil.removeFilesSync(pathRep);
    }
    final urlRepo = getRepositoryPath(url);
    final cmdClone = 'git clone $urlRepo $pathRep';
    await ProcessUtil.runCmdWait(cmd: cmdClone, workingDirectory: pathRep);

    remoteBranchList = await getRemoteBranchList(pathRep);
    hasBranch = remoteBranchList.contains(branch);
  }

  if (hasBranch) {
    // 首先判断远程是否有该分支
    final cmdCheckout = 'git checkout $branch';
    await ProcessUtil.runCmdWait(cmd: cmdCheckout, workingDirectory: pathRep);
  } else {
    // 若当前为空仓库，则master分支不存在，默认不执行操作
    if (branch != 'master') {
      final cmdCheckoutTarget = 'git checkout -b $branch master';
      await ProcessUtil.runCmdWait(
        cmd: cmdCheckoutTarget,
        workingDirectory: pathRep,
      );
    }
  }
