即使 PS 脚本已成功执行，Jenkins Job 仍然失败

Question

我有下面的脚本

停止网络服务

删除网络服务

将项目从 Jenkins 工作区复制到服务器路径

创建网络服务

启动网络服务

我在 Jenkins 作业中运行这个 PS 脚本，执行后，我收到一封电子邮件，因为构建失败。

val STOPPED
[SC] DeleteService SUCCESS
val DELETED
Remove-Item : Cannot remove item \Location.dll: Access to the 
path '\Location.dll' is denied.

我的PS脚本

# force strict - so any variable used before being assigned causes an error
Set-PsDebug -Strict

# force PowerShell to exit with a non-zero code on teh first error
$ErrorActionPreference = 'Stop'

# set $LASTEXITCODE to zero, so the script doesn't fail if no exit code returned
$LASTEXITCODE = 0

# set directories here once, so we can reuse
$MystiflySearchDir = "\Location"
$ReleaseDir   = "C:\Location"

# get directory contents (are you expecting these to return to Jenkins?)
Get-ChildItem "$ReleaseDir\*"

# create the search directory if it doesn't exist
if (-not (Test-Path -Path $val -PathType Container)) { New-Item -Path $val-type directory -Force }

# get the service, but fail gracefully if it doesn't exist
$service = Get-Service -Name val -Computername $env:SERVER -ErrorAction SilentlyContinue

# if we have a service, stop and delete it
if($service.Status)
{
    sc.exe \$env:SERVER stop val 
    if ($LASTEXITCODE -ne 0) { throw "error stopping the service: $LASTEXITCODE" }
    Write-Host "val STOPPED"
    Start-Sleep -s 10
    sc.exe \$env:SERVER delete val
    if ($LASTEXITCODE -ne 0) { throw "error deleting the service: $LASTEXITCODE" }
    Write-Host "val DELETED"
    Start-Sleep -s 25
    Remove-Item "$val\*" -Force -Recurse
}

# copy release to search
xcopy "$ReleaseDir\*" $val/k/e/d/Y

# (re)create the service
sc.exe \$env:SERVER create val start=auto DisplayName= "value"  binPath= D:\Location.exe
if ($LASTEXITCODE -ne 0) { throw "error creating the service: $LASTEXITCODE" }
sc.exe \$env:SERVER description val "val"
if ($LASTEXITCODE -ne 0) { throw "error adding description to service: $LASTEXITCODE" }
sc.exe \$env:SERVER start val
if ($LASTEXITCODE -ne 0) { throw "error starting the service: $LASTEXITCODE" }
Write-Host "val STARTED"

这里有什么我遗漏的吗

Answer 1

您的代码需要稍微整理一下，因为您有几个重复的部分，无论服务是否存在都会执行这些部分。还翻转了 if 逻辑。

在您的代码开头添加了一些步骤，使 PowerShell 更加严格并在 non-zero 代码出现任何错误时退出。

这还没有经过测试，所以可能需要一点fine-tuning。但是，应该有 95%，希望如此！

# force strict - so any variable used before being assigned causes an error
Set-PsDebug -Strict
# force PowerShell to exit with a non-zero code on the first error
$ErrorActionPreference = 'Stop'

# set $LASTEXITCODE to zero, so the script doesn't fail if no exit code returned
$LASTEXITCODE = 0

# se directories her once, so we can reuse
$AirSearchDir = "\Location"
$ReleaseDir   = "C:\Location"

# get directory contents (are you expecting these to return to Jenkins?)
Get-ChildItem "$ReleaseDir\*"

# create the search directory if it doesn't exist
if (-not (Test-Path -Path $AirSearchDir -PathType Container)) { New-Item -Path $AirSearchDir -type directory -Force }

# get the service, but fail gracefully if it doesn't exist
$service = Get-Service -Name val -Computername $env:SERVER -ErrorAction SilentlyContinue
# if we have a service, stop and delete it
if($service.Status)
{
    sc.exe \$env:SERVER stop val 
    if ($LASTEXITCODE -ne 0) { throw "error stopping the service: $LASTEXITCODE" }
    Write-Host "val STOPPED"
    sc.exe \$env:SERVER delete val 
    if ($LASTEXITCODE -ne 0) { throw "error deleting the service: $LASTEXITCODE" }
    Write-Host "val DELETED"
}

# copy release to search
Copy-Item "$ReleaseDir\*" $AirSearchDir -Force -Recurse

# (re)create the service
sc.exe \$env:SERVER create val start=auto DisplayName="val"  binPath= D:\Location.exe
if ($LASTEXITCODE -ne 0) { throw "error creating the service: $LASTEXITCODE" }
sc.exe \$env:SERVER description val "val"
if ($LASTEXITCODE -ne 0) { throw "error adding description to service: $LASTEXITCODE" }
sc.exe \$env:SERVER start val
if ($LASTEXITCODE -ne 0) { throw "error starting the service: $LASTEXITCODE" }
Write-Host "val STARTED"

尝试运行使用管理员帐户的 Jenkins，出现此错误的原因是您的 jenkins 用户无法与服务交互。

运行它与管理员帐户将赋予它足够的权限与其他服务进行交互。

即使 PS 脚本已成功执行，Jenkins Job 仍然失败
