我已经在AWS CodeBuild中配置了CI / CD管道，并以GitHub monorepo作为源。当我将分支合并到master时，它将触发构建。
在yaml文件中配置的版本具有后续的git命令，当我尝试运行git fetch时，出现引用头错误：

Previous HEAD position was 46369d0 Update buildspec.yaml
Switched to branch 'master'

我已经尝试过git reset和git rm -r --cached，但是我可以解决这个问题。
当我推送到master分支后触发构建时，构建成功完成。在容器中更新存储库后，我运行lerna publish来更新软件包版本并使用Terraform部署所有资源。
