错误：src refspec master 与 VSTS 中的 powershell 不匹配

Question

我有一个 powershell 脚本，它从 SFTP 下载文件，然后尝试将它们提交到 git，但是我在最后一步遇到了问题。

try
{
    # Load WinSCP .NET assembly
   Add-Type -Path  "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "myhostname"
        UserName = "myusername"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 myfingerprint"
        #GiveUpSecurityAndAcceptAnySshHostKey = "true" 
    }

    $session = New-Object WinSCP.Session

    try
    {
        New-Item -ItemType directory -Path "C:\tempfolder"

        # Connect
        $session.Open($sessionOptions)

        # Download files
        $transferOptions = New-Object WinSCP.TransferOptions
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary

        $transferResult =
            $session.GetFiles("/BE_Test3rdPartyUpload2VSTS/Project1/upload/*", "c:\tempfolder\*", $False, $transferOptions)

        # Throw on any error
        $transferResult.Check()

        # Print results
        foreach ($transfer in $transferResult.Transfers)
        {
            Write-Host "Download of $($transfer.FileName) succeeded"
        }

        git config --global user.email "myusername"
        git config --global user.name "myname"

        git pull --rebase origin master
        git push origin master


        git add .
        git commit -m "Add existing file"
        git push origin "master"
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    exit 0
}
catch [Exception]
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}

我的错误是这样的：

要将更改推送到 master 分支，您应该从以下方面更改 powershell 脚本：

1. 取消选择 PowerShell 任务的标准错误失败选项

   由于大多数 git 命令显示非标准输出，因此您需要取消选择 PowerShell 任务的 Fail on Standard Error 选项，否则 PowerShell 将失败。

2. git repo URL 中的提供者凭据

   将更改推送到远程仓库时，您需要提供提供者凭据。您可以在 git repo URL 中使用 PAT 或备用凭据。 git repo URL 格式如下：

   https://Personal%20Access%20Token:{PAT}@{account}.visualstudio.com/{project}/_git/{repo}
   https://{AlternateUserName}:{AlternatePassword}@{account}.visualstudio.com/{project}/_git/{repo}
   

   所以你应该用命令推送：

   git push https://Personal%20Access%20Token:{PAT}@{account}.visualstudio.com/{project}/_git/{repo} master
   

   或者

   git push https://{AlternateUserName}:{AlternatePassword}@{account}.visualstudio.com/{project}/_git/{repo} master
   

3. 结帐到构建分支

   在构建源目录中，git repo默认在HEAD detached中，所以需要通过以下方式切换到构建分支：

   git checkout $(Build.SourceBranchName)
   

4. 删除不必要的命令

   脚本中的以下两个命令似乎对本地 master 分支和远程 master 分支都没有更改：

   git pull --rebase origin master
   git push origin master
   

因此您可以在脚本中删除它们。

以下是更改后的 powershell 脚本的示例：

try
{
    # Load WinSCP .NET assembly
   Add-Type -Path  "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "myhostname"
        UserName = "myusername"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 myfingerprint"
        #GiveUpSecurityAndAcceptAnySshHostKey = "true" 
    }

    $session = New-Object WinSCP.Session

    try
    {
        New-Item -ItemType directory -Path "C:\tempfolder"

        # Connect
        $session.Open($sessionOptions)

        # Download files
        $transferOptions = New-Object WinSCP.TransferOptions
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary

        $transferResult =
            $session.GetFiles("/BE_Test3rdPartyUpload2VSTS/Project1/upload/*", "c:\tempfolder\*", $False, $transferOptions)

        # Throw on any error
        $transferResult.Check()

        # Print results
        foreach ($transfer in $transferResult.Transfers)
        {
            Write-Host "Download of $($transfer.FileName) succeeded"
        }

        git config --global user.email "myusername"
        git config --global user.name "myname"

        git checkout $(Build.SourceBranchName)

        git add .
        git commit -m "Add existing file"
        git push https://Personal%20Access%20Token:tp3iai4yextum26xa6k6qbflhjrvpt4jcaak8fkhbhlpis7zkndq@marinaliu.visualstudio.com/Git2/_git/product1 master 
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    exit 0
}
catch [Exception]
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}
