构建步骤“Windows PowerShell”将构建标记为失败，为什么？

以下是 Jenkins 中运行的三个 PowerShell 命令以及构建结果。为什么会失败？哪个命令可能会失败？我读过这篇文章：执行 Shell 如何/何时在 Jenkins 中将构建标记为失败？ https://stackoverflow.com/questions/22814559/how-when-does-execute-shell-mark-a-build-as-failure-in-jenkins，但无法弄清楚。我对MS的东西不太熟悉。

命令1：

& "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.com" "$env:WORKSPACE\ETL\OnePnL.sln" /Build

命令2：

###########################
# Deploy SSIS package           #
###########################  
$csource ="$env:WORKSPACE\ETL\Project Type 0\bin\DEFAULT\OnePnL.ispac"
$cserver = "SSASDBDEV01"
$cdest = "/SSISDB/OnePnL/OnePnL"    
echo $env:GIT_BRANCH    
if ($env:GIT_BRANCH  -like '*master*')
{
   # Call IS Deployment Wizard
   echo "Deploying SSIS package to $cdest on $cserver"    
   # "C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\ISDeploymentWizard.exe" "/Silent /SourcePath:""$csource""    #/DestinationPath:""$cdest"" /DestinationServer:""$cserver""" -Wait
   Start-Process "C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\ISDeploymentWizard.exe" "/Silent /SourcePath:""$csource""    /DestinationPath:""$cdest"" /DestinationServer:""$cserver""" -Wait
}

命令3：

#####################
# Copy Files to O: drive #
#####################

#Make build directory

#$outputparentdir = "\\orion\Shared\AppUpload\ApplicationPackage\OnePnL Cube\SSIS Jenkins Builds"
$outputparentdir = "\\inv\Shared\Transfer - Deleted Weekly\Jenkins\BI\OnePnL\SSIS Jenkins builds"
$outputdir = "$outputparentdir\${env:GIT_BRANCH}\Build ${env:BUILD_NUMBER}"
echo "Branch"
echo ${env:GIT_BRANCH}

echo "Output directory"
echo $outputdir 

if (!(Test-Path "$outputparentdir"))
{
  mkdir $outputparentdir
}

mkdir $outputdir

ROBOCOPY "$env:WORKSPACE\ETL\Project Type 0\bin\DEFAULT" "$outputdir" /E /v

echo "Done Copy"

构建结果：

Done Copy


Build step 'Windows PowerShell' marked build as failure

答案就在您链接的帖子中。

the 最后一个命令的退出代码Jenkin 的执行 Shell 构建步骤的决定了构建步骤的成功/失败

我知道你已经明白了这么多，但是让它发挥作用的是robocopy 的返回代码 https://support.microsoft.com/en-us/kb/954404这是你最后的命令。虽然该链接适用于服务器 2008，但如果它们是通用操作系统，我不会感到惊讶。

Value   Description
0       No files were copied. No failure was encountered. No files were mismatched. The files already exist in the destination directory; therefore, the copy operation was skipped.
1       All files were copied successfully.

如果所有文件均已成功复制，则返回代码为 1。Anything正如我们在链接问题中所读到的，除了 0 之外的其他值都被构建步骤报告为失败。

我认为你需要做的是检查 robocopy 的返回码并更改它。

要检查它，您需要查看PowerShell 自动变量 $? https://technet.microsoft.com/en-us/library/hh847768.aspx

$?
包含上次操作的执行状态。它包含 如果上次操作成功则为 TRUE，如果失败则为 FALSE。

所以最后几行可能是......

ROBOCOPY "$env:WORKSPACE\ETL\Project Type 0\bin\DEFAULT" "$outputdir" /E /v
If($?){exit 0}

这应该做的是从 robocopy 获取任何非零结果并强制脚本返回 true。再次请注意，这将为所有返回代码返回 OK。如果这是不可取的，那么您可以轻松地为某些代码构建一些逻辑。

我无法真正测试这段代码，因为我没有你的环境，但理论上它应该可以工作，或者至少可以让你开始你需要的地方。
