直接在jenkins管道中执行powershell命令 [英] Executing powershell command directly in jenkins pipeline

问题描述

是否可以在管道常规脚本中直接调用PowerShell命令?在Jenkins中使用自定义作业时，我可以使用PowerShell插件调用该命令.但是在groovy脚本中没有片段可以使用.

Is it possible to call a PowerShell command directly in the pipelines groovy script? While using custom jobs in Jenkins I am able to call the command with the PowerShell Plugin. But there is no snippet to use this in the groovy script.

我也尝试过sh()，但是似乎该命令不允许命令中包含多行和注释.

I also tried sh() but it seems that this command does not allow multiple lines and comments inside the command.

推荐答案

要从Groovy脚本调用PowerShell脚本:

To call a PowerShell script from the Groovy-Script:

• 您必须使用bat命令.
• 此后，您必须确保正确返回错误代码(errorlevel)变量(EXIT 1应导致FAILED作业).
• 最后，要与PowerShell-Plugin兼容，您必须确保将考虑使用$LastExitCode.
• 我注意到'powershell'现在可以在管道中使用，但是由于存在多个问题，因此我更喜欢此变体.仍在等待它稳定.实际上，我的"dontKillMe"行为存在问题.

• you have to use the bat command.
• After that, you have to be sure that the Error Code (errorlevel) variable will be correctly returned (EXIT 1 should resulting in a FAILED job).
• Last, to be compatible with the PowerShell-Plugin, you have to be sure that $LastExitCode will be considered.
• I have notice that the 'powershell' is now available in pipeline, but since it have several issues I prefer this variant. Still waiting it works stabil. I actually have an issue with the 'dontKillMe' behavior.

为此，我写了一些时髦的方法，可以将其集成到任何管道脚本中:

For that porpuse I have written a little groovy method which could be integrate in any pipeline-script:

def PowerShell(psCmd) {
    psCmd=psCmd.replaceAll("%", "%%")
    bat "powershell.exe -NonInteractive -ExecutionPolicy Bypass -Command \"\$ErrorActionPreference='Stop';[Console]::OutputEncoding=[System.Text.Encoding]::UTF8;$psCmd;EXIT \$global:LastExitCode\""
}

我添加了UTF8 OutputEncoding:与Server 2016和Win10一起使用非常好.[/EDIT] 我添加了'％'掩码[/EDIT]

然后，您可以在管道脚本中这样调用脚本:

In your Pipeline-Script you could then call your Script like this:

stage ('Call Powershell Script')
{
    node ('MyWindowsSlave') {
        PowerShell(". '.\\disk-usage.ps1'") 
    }
}

该方法的最好之处在于，您可以调用CmdLet而不用在脚本中进行操作，这是最佳实践.

The best thing with that method, is that you may call CmdLet without having to do this in the Script, which is best-praxis.

调用ps1定义CmdLet，然后调用CmdLet

Call ps1 to define CmdLet, an then call the CmdLet

PowerShell(". '.\\disk-usage.ps1'; du -Verbose")

• 别忘了使用 withEnv()，那么比完全兼容Powershell插件要好.
• 使用.推迟脚本，以确保当脚本返回错误代码时应该执行此步骤(应优先使用)，如果您不关心它，请使用&.
• Do not forget to use withEnv() an then you are better than fully compatible with the Powershell plugin.
• postpone your Script with . to be sure your step failed when the script return an error code (should be preferred), use & if you don't care about it.
