我已经密切关注了here，here和here设计指南，但我不断收到此PowerShell错误：
由于一个或多个缺少必需参数而无法处理命令：SourcePath FilePattern BuildRegex。
相关配置数据如下。
我已经检查并仔细检查以确保变量存在于我的GET_ACCOUNTS文件中。我还查看了其他工作任务的配置（例如VSBuild），并且变量声明和PowerShell执行语法没有显着差异。
这里可能出现什么问题？这是一个非常简单的架构 - 没有什么可以打破的。但显然有些事情已经做到了。
来自task.json：

显然我没有足够密切关注......我错过了this page上的警告：
警告字
可以对任务进行版本控制，将此用于您的优势。所有构建定义都使用特定任务的最新可用版本，您无法从Web界面更改此行为，因此始终假设正在使用最新版本。
如果在更新任务时未更改任务的版本号，则之前使用过您的任务的构建代理将不会下载较新版本，因为版本号仍然相同。这意味着如果您更改任务的行为，则应始终更新版本号！
一旦我完全理顺了，一切都运转良好。

可能接受参数部分输入的示例已过时。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
