GitLab CI流水线未生成LICENSE文件问题求助

我希望通过GitLab CI流水线确保仓库拥有合规的LICENSE文件。运行器部署在Mac系统上，是shell类型且状态正常。流水线显示执行成功，但LICENSE文件并未被创建；再次运行流水线仍显示成功，却始终进入if分支而非else分支，每次都输出添加MIT许可证的相关内容，推送的代码目标分支为main，不清楚遗漏了哪些配置或步骤？

用户提供的.gitlab-ci.yml配置如下：

stages:
  - add-license

Add-MIT-License:
  stage: add-license
  script:
    - echo "This is the current working dir $(pwd)"
    - echo "Job is running"
    - |
      if [ ! -f LICENSE ]; then
        echo "Adding MIT License..."
        echo "MIT License" > LICENSE
        echo "" >> LICENSE
        echo "Permission is hereby granted, free of charge, to any person obtaining a copy" >> LICENSE
        echo "of this software and associated documentation files (the 'Software'), to deal" >> LICENSE
        echo "in the Software without restriction, including without limitation the rights" >> LICENSE
        echo "to use, copy, modify, merge, publish, distribute, sublicense, and/or sell" >> LICENSE
        echo "copies of the Software, and to permit persons to whom the Software is" >> LICENSE
        echo "furnished to do so, subject to the following conditions:" >> LICENSE
        echo "" >> LICENSE
        echo "The above copyright notice and this permission notice shall be included in all" >> LICENSE
        echo "copies or substantial portions of the Software." >> LICENSE
        echo "" >> LICENSE
        echo "THE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND, EXPRESS OR" >> LICENSE
        echo "IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY," >> LICENSE
        echo "FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE" >> LICENSE
        echo "AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER" >> LICENSE
        echo "LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM," >> LICENSE
        echo "OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE" >> LICENSE
        echo "SOFTWARE." >> LICENSE
        echo "MIT License file added."
      else
        echo "MIT License file already exists."
      fi
  only:
    - main

1. 未将生成的LICENSE文件提交推送回仓库 #

GitLab CI的shell运行器仅在本地运行器的工作目录生成了LICENSE文件，但没有将文件提交并推送到Git仓库。因此仓库中始终不存在LICENSE，每次流水线检测时都会进入创建分支。

解决方法：在脚本末尾添加Git提交和推送步骤，同时确保运行器用户有仓库的推送权限：

# 配置Git用户信息（首次运行需设置，也可提前在运行器系统中配置）
git config --global user.name "GitLab CI Runner"
git config --global user.email "runner@your-domain.com"

# 提交生成的LICENSE文件
git add LICENSE
git commit -m "Add MIT License via GitLab CI"

# 推送到main分支
git push origin main

2. 工作目录路径或文件存在性验证问题 #

可以在脚本中添加目录内容查看命令，确认当前工作目录是否为仓库的正确克隆目录，以及文件是否真的被生成：

# 在脚本开头添加，查看当前目录文件
ls -la

# 在生成LICENSE后添加，确认文件是否存在
echo "Generated LICENSE details:"
ls -la LICENSE
cat LICENSE

3. 文件存在性判断的兼容性问题（Mac系统） #

Mac系统默认使用zsh或bash，可尝试将文件存在性判断改为更兼容的写法，避免因shell差异导致判断错误：

# 将原判断语句替换为
if [ ! -e LICENSE ]; then
