git - 为什么 Gitlab CI 无法获取 git 子模块但在随后的推送中检查出子模块？

问题描述

我的项目由一个父项目和一个子项目组成。子项目作为子模块包含在父项目中。

我正在使用 Gitlab CI。下面是 .gitlab-ci.yml 文件。

stages:
 - build

variables:
  GIT_SUBMODULE_STRATEGY: recursive
  
build-backend:
  image: mcr.microsoft.com/dotnet/core/sdk:3.1
  stage: build
  script:
    - echo "build-backend"
    - apt update -y
    - apt install -y nodejs npm
    - node --version
    - npm --version
    - ls -al MyApp/client
    - dotnet publish MyApp /p:PublishProfile="Profile"

gitmodules 文件看起来像这样

[submodule "MyApp/client"]
    path = MyApp/client
    url = ../myappclient.git
    branch = master

如果我对源代码进行更改并推送到 Gitlab，那么 Gitlab 会失败并出现此错误

fatal: destination path '/builds/def/abc/xyz/MyApp/client' already exists and is not an empty directory.

如果我推动另一个更改（任何人为的更改），那么构建工作。

  1. 为什么Gitlab第一次获取子模块失败？
  2. 我需要在最后一次构建后清理吗？
