GitLab CI本地include规则仅生效最后一条问题求助

我按照GitLab CI文档配置了分支特定的include规则，意图在dev分支加载.gitlab-ci-dev.yml，main分支加载.gitlab-ci-master.yml，配置如下：

include:
    - local: .gitlab-ci-dev.yml
      rules:
          - if: $CI_COMMIT_BRANCH == "dev"
    - local: .gitlab-ci-master.yml
      rules:
          - if: $CI_COMMIT_BRANCH == "main"

但实际执行时，无论当前分支是dev还是main，始终只加载.gitlab-ci-master.yml中的变量。完整CI配置文件如下：

完整配置文件 #

.gitlab-ci.yml #

include:
    - local: .gitlab-ci-dev.yml
      rules:
          - if: $CI_COMMIT_BRANCH == "dev"
    - local: .gitlab-ci-master.yml
      rules:
          - if: $CI_COMMIT_BRANCH == "main"
stages:
    - build
    - tests
    - deploy
before_script:
    - echo $iis_application_path
    - echo $application_pool_name
    - echo $CI_COMMIT_BRANCH
    - echo $CI_COMMIT_BRANCH == "AjmanTaxi"
build:
    stage: build
    script:
        - dotnet restore
        - dotnet build --no-restore
        - dotnet publish .\apicicdtest\apicicdtest.csproj -c Release -o $publish_path
    artifacts:
        paths:
            - $publish_path
        expire_in: '1 hrs'
    tags:
        - windows
    only:
        - branches

deploy:
    stage: deploy
    script:
        - |
            if((Get-WebAppPoolState -Name $application_pool_name).Value -ne 'Stopped'){
                 Write-Output ('Stopping Application Pool: {0}' -f $application_pool_name)
                 Stop-WebAppPool -Name $application_pool_name
                 New-Item -Path $iis_application_path -Name "app_offline.htm" -ItemType "file"
            }

        - Start-Sleep -s 5
        - Copy-Item ($publish_path + "*") -Destination $iis_application_path -recurse
        - |
            if((Get-WebAppPoolState -Name $application_pool_name).Value -ne 'Started'){
                Write-Output ('Starting Application Pool: {0}' -f $application_pool_name)
                if(Test-Path $iis_application_path\app_offline.htm){
                    Remove-Item -Path $iis_application_path\app_offline.htm
                }
                Start-WebAppPool -Name $application_pool_name
            }
    only:
        - branches
    tags:
        - windows
    dependencies:
        - build

.gitlab-ci-dev.yml #

variables:
    publish_path: 'bin\Release\net7.0\publish\'
    application_pool_name: 'testcicddev'
    application_name: 'testcicddev'
    iis_application_path: 'E:\temp_files\cicdtestpublishdev'

.gitlab-ci-master.yml #

variables:
    publish_path: 'bin\Release\net7.0\publish\'
    application_pool_name: 'testcicdmaster'
    application_name: 'testcicdmaster'
    iis_application_path: 'E:\temp_files\cicdtestpublishmaster'

解决思路 #

• 校验分支名称匹配度：查看流水线输出的$CI_COMMIT_BRANCH值，确认是否与规则中的分支名完全一致（注意大小写、拼写，比如是否是Dev而非dev，Main而非main）。从你的before_script输出可以看到有echo $CI_COMMIT_BRANCH == "AjmanTaxi"，需确认实际分支名是否为规则中指定的dev或main。
• 明确规则默认行为：为每个include的rules添加默认不加载的逻辑，避免潜在的规则匹配异常：

  include:
    - local: .gitlab-ci-dev.yml
      rules:
        - if: $CI_COMMIT_BRANCH == "dev"
          when: always
        - when: never
    - local: .gitlab-ci-master.yml
      rules:
        - if: $CI_COMMIT_BRANCH == "main"
          when: always
        - when: never
  

• 检查变量优先级：确认项目级、群组级或实例级变量中是否存在同名变量，这类变量优先级高于include文件中定义的变量，会覆盖后者。
• 验证include加载情况：在流水线页面的「CI/CD configuration」选项中，查看实际加载的配置文件列表，确认对应分支的include是否生效，定位是规则未匹配还是变量被覆盖。
• GitLab版本兼容性：如果使用的GitLab版本较旧，可能存在include规则的bug，建议升级到支持include rules的稳定版本（GitLab 12.0+开始支持该特性，但部分细节在后续版本完善）。
