获取 TFS 构建过程参数

Question

我正在尝试从 PowerShell 脚本更新构建定义，但在尝试反序列化进程参数时遇到了问题。

我的脚本

add-type -Path 'C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Client.dll'
add-type -Path 'C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Build.Client.dll'
add-type -Path 'C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Build.Common.dll'
add-type -Path 'C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Build.Workflow.dll'

$tfsCollectionUrl = "http://{myurl}/tfs/{mycollection}"
$server = new-object Microsoft.TeamFoundation.Client.TfsTeamProjectCollection(New-Object Uri($tfsCollectionUrl))
$buildServer = $server.GetService([Microsoft.TeamFoundation.Build.Client.IBuildServer])
$buildDef = $buildServer.GetBuildDefinition("{MyProjectName}", "{MyBuildName}")
$processParams = [Microsoft.TeamFoundation.Build.Workflow.WorkflowHelpers]::DeserializeProcessParameters($buildDef.ProcessParameters)
$processParams

还有错误

Exception calling "DeserializeProcessParameters" with "1" argument(s): "Set property 'Microsoft.TeamFoundation.Build.Common.BuildParameter.Json' threw an exception."
At line:14 char:1
+ $processParams = [Microsoft.TeamFoundation.Build.Workflow.WorkflowHel ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : XamlObjectWriterException

我所看到的关于如何做我想做的事情（即更新内部版本号格式）的所有内容都给了我这个确切的代码，所以不知道从哪里开始。构建定义和过程参数确实回来了，只是不是以我真正可以使用的方式。

我们使用的是 TFS 2013 Update 4，cmdlet 来自 2013 TFS PowerTools。

我缺少对 Newtonsoft.Json.dll 的引用：

Add-Type -Path "C:\Folder\SharedAssemblies\Newtonsoft.Json.dll"

我把它加进去了，一切都很好。

最终脚本：

Add-Type -Path "C:\{Folder}\SharedAssemblies\Newtonsoft.Json.dll"
Add-Type -Path "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Client.dll"
Add-Type -Path "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Build.Client.dll"
Add-Type -Path "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Build.Workflow.dll"

$tfsCollectionUrl = "http://{myurl}/tfs/{mycollection}"
$server = new-object Microsoft.TeamFoundation.Client.TfsTeamProjectCollection(New-Object Uri($tfsCollectionUrl))
$buildServer = $server.GetService([Microsoft.TeamFoundation.Build.Client.IBuildServer])

$buildDefinition = $buildServer.GetBuildDefinition("{MyProjectName}", "{MyBuildName}")

$processParams = [Microsoft.TeamFoundation.Build.Workflow.WorkflowHelpers]::DeserializeProcessParameters($buildDefinition.ProcessParameters)
$processParams.BuildNumberFormat = "`$(BuildDefinitionName)_`$(Year:yy).222.0`$(Rev:.r)"

$buildDefinition.ProcessParameters = [Microsoft.TeamFoundation.Build.Workflow.WorkflowHelpers]::SerializeProcessParameters($processParams)
$buildDefinition.Save()
