在 powershell 构建步骤中出现“=”错误后缺少表达式

Question

我正在进行团队城市建设步骤。这是我使用 %teamcity.build.branch% 和 %teamcity.build.checkoutDirectory% 参数的 powershell 步骤。这是脚本：

param([string]$branchName=%teamcity.build.branch%, [string]$bldCheckOutDir=%teamcity.build.checkoutDir%)

write "Value of branchName is $branchName"
write "Value of bldCheckOutDir is $bldCheckOutDir"

if ($branchName.Substring(0,1) -like "F") {Write "Working on a Feature Branch"; CD $bldCheckOutDir\DCD-GUI; npm test; sonar-scanner -X}
elseif ($branchName.Substring(0,2) -like "US") {Write "Working on a Story Branch"}
elseif ($branchName.Substring(0,2) -like "DE") {Write "Working on a Defect Branch"}
elseif ($branchName.Substring(0,2) -like "QA") {Write "Working on a QA1 Branch"; CD $bldCheckOutDir\DCD-GUI; npm test; CD ..; FortifyBatchFile.bat; sonar-scanner -X; }
else {Write "BranchName not known"}

当我在构建配置中将此脚本作为构建步骤运行时，出现以下错误：

【Step 4/4】工作目录：E:\BuildAgent\work\d429bf6e9117eae6 [04:25:58][步骤 4/4] PowerShell 参数：[-NonInteractive, -ExecutionPolicy、ByPass、-File、E:\BuildAgent\temp\buildTmp\powershell6621137048056018482.ps1] [04:26:08][步骤 4/4] '=' 后缺少表达式。 [04:26:08][步骤 4/4] 在 E:\BuildAgent\temp\buildTmp\powershell6621137048056018482.ps1:1 char:27 [04:26:08][Step 4/4] + param([string]$branchName= : ParserError: (=:String) [], ParentContainsErrorR [04:26:08][步骤 4/4] ecodException [04:26:08][步骤 4/4] + FullyQualifiedErrorId : MissingExpressionAfterToken

我在这里做错了什么？

Answer 1

在参数块中，您需要将 teamcity 变量用双引号或单引号括起来：

param(
    [string]$branchName = "%teamcity.build.branch%",
    [string]$bldCheckOutDir = "%teamcity.build.checkoutDir%"
)

没有它们，% 字符可能会被视为特殊字符。
