TFS 2015.3 自定义构建步骤不向脚本发送变量

Question

我已严格遵循找到的设计指南 here, here and here，但我不断收到此 PowerShell 错误：

Cannot process command because of one or more missing mandatory parameters: SourcePath FilePattern BuildRegex.

相关配置数据如下。

我已经反复检查以确保这些变量存在于我的 task.json 文件中。我还查看了其他工作任务（例如 VSBuild）的配置，变量声明和 PowerShell 执行语法没有显着差异。

这里可能出了什么问题？这是一个非常简单的架构——没有什么可以破坏的。但很明显，有些事情已经做到了。

来自task.json：

"inputs": [
  {
    "name": "SourcePath",
    "type": "filePath",
    "label": "Source path",
    "defaultValue": "",
    "required": true,
    "helpMarkDown": "Path in which to search for version files (like AssemblyInfo.* files). NOTE: this is case sensitive for non-Windows systems." 
  },
  {
    "name": "FilePattern",
    "type": "string",
    "label": "File pattern",
    "defaultValue": "AssemblyInfo.*",
    "required": true,
    "helpMarkDown": "File filter to replace version info. The version number pattern should exist somewhere in the file(s). Supports minimatch. NOTE: this is casese sensitive for non-Windows systems."
  },
  {
    "name": "BuildRegEx",
    "type": "string",
    "label": "Build RegEx pattern",
    "defaultValue": "\d+\.\d+\.\d+\.\d+",
    "required": true,
    "helpMarkDown": "Regular Expression to extract version from build number. This is also the default replace RegEx (unless otherwise specified in Advanced settings)."
  },
  {
    "name": "BuildRegExIndex",
    "type": "string",
    "label": "Build RegEx group index",
    "defaultValue": "0",
    "required": false,
    "helpMarkDown": "Index of the group in the Build RegEx that you want to use as the version number. Leave as 0 if you have no groups.",
    "groupName": "advanced"
  },
  {
    "name": "ReplaceRegEx",
    "type": "string",
    "label": "RegEx replace pattern",
    "defaultValue": "",
    "required": false,
    "helpMarkDown": "RegEx to replace with in files. Leave blank to use the Build RegEx Pattern.",
    "groupName": "advanced"
  },
  {
    "name": "ReplacePrefix",
    "type": "string",
    "label": "Prefix for replacements",
    "defaultValue": "",
    "required": false,
    "helpMarkDown": "Prefix for the RegEx result string.",
    "groupName": "advanced"
  },
  {
    "name": "ReplaceSuffix",
    "type": "string",
    "label": "Suffix for replacements",
    "defaultValue": "",
    "required": false,
    "helpMarkDown": "Suffix for the RegEx result string.",
    "groupName": "advanced"
  },
  {
    "name": "FailIfNoMatchFound",
    "type": "boolean",
    "label": "Fail if no target match found",
    "defaultValue": "false",
    "required": false,
    "helpMarkDown": "Fail the build if no match is found for the replace RegEx in the target file(s).",
    "groupName": "advanced"
  }
],
"execution": {
  "PowerShell3": {
    "target": "VersionAssembly.ps1"
  }
}

来自VersionAssembly.ps1：

[CmdletBinding()]
param(
  [string][Parameter(Mandatory=$True)][ValidateNotNullOrEmpty()] $SourcePath,
  [string][Parameter(Mandatory=$True)][ValidateNotNullOrEmpty()] $FilePattern,
  [string][Parameter(Mandatory=$True)][ValidateNotNullOrEmpty()] $BuildRegex,
  [string]$BuildRegexIndex,
  [string]$ReplaceRegex,
  [string]$ReplacePrefix,
  [string]$ReplaceSuffix,
  [string]$FailIfNoMatchFound,
  [string]$BuildNumber = $ENV:BUILD_BUILDNUMBER
)

Answer 1

显然我没有密切关注...我错过了 this page 上的警告：

Words of warning

Tasks can be versioned, use this to your advantage. All build definitions use the latest available version of a specific task, you can’t change this behavior from the web interface, so always assume the latest version is being used.

If you don’t change the version number of your task when updating it, the build agents that have previously used your task will not download the newer version because the version number is still the same. This means that if you change the behavior of your task, you should always update the version number!

一旦我弄清楚了一切，一切正常。

可能在参数部分接受输入的例子已经过时了。看来您现在需要使用 PowerShell 脚本中的 Vsts-task-lib 命令来获取输入参数。

[CmdletBinding()]
param()

$myParam = Get-VstsInput -Name myParam -Require
