使用 Docker 直接运行，打开项目后提示“No HEAD exists and no explicit starting revision was specifiedDISMISS”

使用 Docker 直接运行：

> docker run -d --name webide -p 8080:8080 -v /docker/webide:/root/.coding-ide --restart=always webide/webide

添加好 SSH GIT 项目后，打开项目，没有代码文件树目录，并有红色提示框提示：

> No HEAD exists and no explicit starting revision was specifiedDISMISS

WebDebug 发现仅有一个连接 500 错误：

> http://192.168.1.3:8080/git/wdyoib/logs?size=30&page=0

Bắt đầu với endpoint /git/{project}/logs và stack trace trong GitController.java:328, sau đó theo dõi GitManagerImpl.java:1018 và :1084, nơi JGit LogCommand bị lỗi. Tái hiện thiết lập Docker với một dự án Git qua SSH và kiểm tra trạng thái repository khi nó không có HEAD. Hoàn thành có nghĩa là khi mở dự án, cây tệp của dự án được hiển thị mà không có phản hồi 500 từ endpoint logs.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
