如何解决Azure Yaml Pipelines Powershell任务参数中的MissingEndParenthesisInExpression问题 [英] How to troubleshoot MissingEndParenthesisInExpression in Azure Yaml Pipelines powershell task arguments

问题描述

yaml PowerShell任务看起来像这样:

yaml PowerShell task looks something like this:

- task: PowerShell@2
  displayName: 'test'
  inputs:
    targetType: filePath
    filePath: '$(Agent.BuildDirectory)\$(artifactName)\testpath\testscript.ps1'
    arguments: '-parameterFilePath $(Agent.BuildDirectory)\$(artifactName)\mainfolder\params.json -appSecurePassword (convertTo-SecureString $(appPassword) -AsPlainText -Force) -vmSecurePassword (convertTo-SecureString $(vmPassword) -AsPlainText -Force)'

但是，出现此错误:

有人可以让我知道我在想什么吗?我确信PowerShell脚本没有问题，因为我可以在代理上手动运行它.

Can anyone please let me know what I am missing? I am sure there is no problem with the PowerShell script as I can run that manually on the agent.

推荐答案

上述错误消息 ... urePassword(convertTo-SecureString *** -AsPlainText -Force)表示问题来自powershell任务的 arguments .

The above error message ... urePassword (convertTo-SecureString *** -AsPlainText -Force) indicates the issue comes from the arguments of powershell task.

并且表达式中 Missing close')'的错误表示您的密码中包含("字符.

And the error Missing closing ')' in expression indicates that there is "(" character in your Password.

我在管道上进行了测试，如果密码是"pass(word" (不带双引号).我收到相同的 Missing close')'错误消息.

I tested on my pipeline, if my password is "pass(word"(without double quotes). I got the same Missing closing ')' error message.

在自变量中引用密码时，可以尝试双引号.见下文:

You can try double quoting your passwords when you refer to them in the arguments. See below:

-appSecurePassword (convertTo-SecureString "$(appPassword)" -AsPlainText -Force) -vmSecurePassword (convertTo-SecureString "$(vmPassword)" -AsPlainText -Force)

您也可以尝试使用反引号转义密码中的特殊字符.例如，在管道变量中定义的密码中转义特殊字符(例如"pass`(单词" )

You can also try using backtick to escape the special characters in the password. For example, escape the special characters in the Passwords defined in the pipeline Variables (eg. "pass`(word")

请参见包含特殊字符的密码PowerShell 以获取更多信息.
