我有一个名为A的git代码库，其中包含一个子模块B。当我在A代码库中执行
我尝试了以下解决方法：
完整的错误信息：
git submodule update --init --recursive命令以更新子模块时，会出现Permission denied (publickey)错误。虽然ssh密钥已成功添加到远程Gitlab上，并且我可以独立使用ssh克隆两个代码库，但是在A代码库外克隆B代码库则可行。
代码库B与代码库A在同一Gitlab组内。我尝试了以下解决方法：
- 在
.gitmodules中设置绝对路径 - 将
.gitmodules中的引用更改为http - 对A进行干净的克隆
- 添加新的ssh密钥（有和无密码）
- 使用
--recursive选项克隆A代码库
.gitmodules文件的内容如下：[submodule "B"]
path = path_to_B
url= ../B.git
