Azure DevOps YAML 管道 - git diff 無法正常工作

Question

我正在我的 Azure DevOps YAML 管道中執行 git 命令，以通過 PowerShell 腳本獲取兩次提交之間的更改，例如git diff commit1 commit2 --name-only - 請參閱下面的完整代碼：

Write-Information "git diff --name-only $git_event_before $git_event_after --diff-filter=ACM ""*.txt"""
$txt_files = @($(git diff --name-only $git_event_before $git_event_after --diff-filter=ACM "*.txt"))
$txt_files = $txt_files | ForEach-Object { Join-Path $root_path $_ | Get-Item }

if ($txt_files.Count -eq 0) {
    Write-Error "Something went wrong, could not find any changed .txt files using the above 'git diff'"
}

這會引發一個錯誤，聲稱未找到任何文件。 但是，如果我在本地執行完全相同的git diff命令，我也同步了存儲庫，它會按預期返回更改的文件。

我是否需要手動更新已由管道的結帳步驟下載的存儲庫？

你能嘗試以這種方式運行“git diff”嗎

$gitDiffCmd = 'diff "origin/{0}" "origin/{0}@{{1}}" --name-only' -f $buildSourceBranch
$gitCommitFiles = Invoke-Git $gitDiffCmd

function Invoke-Git {
    [CmdletBinding()]
    [OutputType([string])]
    param (
        [Parameter(Mandatory)]
        [string] $Command 
    )
    try {
        $old_env = $env:GIT_REDIRECT_STDERR
        $env:GIT_REDIRECT_STDERR = '2>&1'
        $response = Invoke-Expression "git $Command "
        return $response
    } catch {
        Write-Host $_.ScriptStackTrace
    } finally {
        $env:GIT_REDIRECT_STDERR = $old_env
    }
}
