您可以在 Azure Azure Devops 的内联脚本中使用 IF 语句吗？

Question

I have a task in Azure Devops which builds a VM

Task 1 builds a VM Task 2 adds datadisks if required

so in task 2 I have an inline powershell script but when i run it it gives an error " The term 'n' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. Not sure why it is giving the error? "

 ###Azure Devops pipeline variable is $(datadisk1required) this has the value 'n'
$datadisk1required = $(datadisk1required)
if ($datadisk1required -eq "n")
{
write-host "datadisk1 not required"
write-host $datadisk1required
}

Answer 1

The substitution of AzDO variables in the script happens before PowerShell runs, and that means that if the inline script definition is:

$powerShellVariable = $(azVariable)

and the value of the azVariable variable in the task is "string", the resulting script passed to PowerShell will be:

$powerShellVariable = string

PowerShell will interpret the bare word string as a command name, hence the error.

Put quotation marks in place around the AzDO variable macro and it'll work:

$datadisk1required = '$(datadisk1required)'
