Azure DevOps YAML 管道 - git diff 无法正常工作答案

【问题标题】：Azure DevOps YAML pipeline - git diff not working correctlyAzure DevOps YAML 管道 - git diff 无法正常工作

【问题描述】：

我正在我的 Azure DevOps YAML 管道中执行一个 git 命令，以通过 PowerShell 脚本获取两个提交之间的更改，例如 git diff commit1 commit2 --name-only - 请参阅下面的完整代码：

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'"
}

这会引发错误，声称未找到任何文件。但是，如果我在本地执行相同的 git diff 命令，我也同步了存储库，它会按预期返回更改的文件。

我是否需要手动更新已通过管道的签出步骤下载的存储库？

你可以尝试以这种方式运行“git diff”

$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
    }
}
