步骤及解释

设置git用户名

git config --global user.email "useremail"
git config --global user.name "username"

获取branch

$branch = "$(Build.SourceBranch)" -replace "refs/heads/"

"$(Build.SourceBranch)"：这是一个环境变量，它包含了触发当前构建的分支的完整引用路径。例如，如果构建是由 main 分支触发的，那么这个变量的值可能是 refs/heads/main。

-replace "refs/heads/"：这是PowerShell中的一个操作符，用于替换字符串中的指定模式。在这里，它用于从 $(Build.SourceBranch) 的值中移除 refs/heads/ 部分，只留下分支的名称。

示例

假设 $(Build.SourceBranch) 的值是 refs/heads/feature/new-feature，那么执行这行命令后：

• 原始值：refs/heads/feature/new-feature
• 处理后的值：feature/new-feature

修改并push

git checkout -b $branch
         
Write-Host "Adding changes to staging area..."
git -C "$(Build.SourcesDirectory)" add **/package.json
Write-Host "Committing changes..."
git -C "$(Build.SourcesDirectory)" commit -m "your change"
Write-Host "Pushing changes to remote repository..."
git -C "$(Build.SourcesDirectory)" -c http.extraheader="AUTHORIZATION: bearer $(System.AccessToken)" push --set-upstream origin $branch 
Write-Host "Done."

整体

- powershell: |
          git config --global user.email "email"
          git config --global user.name "name"
          $branch = "$(Build.SourceBranch)" -replace "refs/heads/"
          Write-Host "this is the $branch"
          git checkout -b $branch
         
                          
          Write-Host "Adding changes to staging area..."
          git -C "$(Build.SourcesDirectory)" add **/package.json
          Write-Host "Committing changes..."
          git -C "$(Build.SourcesDirectory)" commit -m "your changes"
          Write-Host "Pushing changes to remote repository..."
          git -C "$(Build.SourcesDirectory)" -c http.extraheader="AUTHORIZATION: bearer $(System.AccessToken)" push --set-upstream origin $branch
          Write-Host "Done."
        workingDirectory: "$(Build.SourcesDirectory)"
        failOnStderr: false
        displayName: "Update Version number to Repo"

git -C 在某路径下执行

git -c 设置变量
