c# - TFS - 链式构建 - 如何将信息从一个构建传递到下一个构建？

Question

我正在研究一个 TFS 构建定义，该定义通过使用此处博客中的代码启动另一个构建:Queue another Team Build when one Team Build succeeds

我对帖子底部的前几条评论很感兴趣。基本上，我只想将第一个内部版本号传递给下一个版本。

更改 XAML 模板以传递 IBuildRequest 相当简单而不是 IBuildDefinition ...

<Sequence.Variables>
    <Variable x:TypeArguments="mtbc:IBuildDefinition" Default="[BuildServer.GetBuildDefinition(BuildDetail.TeamProject, buildChainItem)]" Name="ChainedBuildDefinition" />
    <Variable x:TypeArguments="mtbc:IBuildRequest" Default="[BuildServer.CreateBuildRequest(ChainedBuildDefinition.Uri)]" Name="ChainedBuildRequest" />
    <Variable x:TypeArguments="mtbc:IQueuedBuild" Default="[BuildServer.QueueBuild(ChainedBuildRequest)]" Name="QueuedChainedBuild" />
</Sequence.Variables>

更棘手的是将当前内部版本号添加到 ProcessParameters 中新的 IBuildRequest .

我可以看到如何使用 Default 添加代码行<Variable> 的属性像上面一样，但似乎每一行都必须返回一些东西。但是我想运行的一些行只是调用一个没有返回值的方法，例如将新元素添加到 ProcessParameters 时字典。这是我尝试过的...

<Sequence.Variables>
    <Variable x:TypeArguments="mtbc:IBuildDefinition" Default="[BuildServer.GetBuildDefinition(BuildDetail.TeamProject, buildChainItem)]" Name="ChainedBuildDefinition" />
    <Variable x:TypeArguments="mtbc:IBuildRequest" Default="[BuildServer.CreateBuildRequest(ChainedBuildDefinition.Uri)]" Name="ChainedBuildRequest" />

    <Variable x:TypeArguments="x:String" Default="[ChainedBuildRequest.ProcessParameters]" Name="NextProcessParameters" />
    <!-- deserialize processparameters string into dictionary -->
    <Variable x:TypeArguments="scg:IDictionary(x:String, x:Object)" Default="[WorkflowHelpers.DeserializeProcessParameters(NextProcessParameters)]" Name="DeserializedProcessParameters" />
    <!-- *** add new parameter, but no return value, so will not work *** -->
    <Variable x:TypeArguments="x:String" Default="[DeserializedProcessParameters.Add(&quot;PreviousBuildNumber&quot;, &quot;1.1.1.1&quot;)]" Name="AddNewParameter" />
    <!-- serialize back into a string -->
    <Variable x:TypeArguments="x:String" Default="[WorkflowHelpers.SerializeProcessParameters(DeserializedProcessParameters)]" Name="SerializedProcessParameters" />
    <!-- *** also no return value, so will not work *** -->
    <Variable x:TypeArguments="x:String" Default="ChainedBuildRequest.ProcessParameters = SerializedProcessParameters" Name="UpdateProcessParameters" />

    <Variable x:TypeArguments="mtbc:IQueuedBuild" Default="[BuildServer.QueueBuild(ChainedBuildRequest)]" Name="QueuedChainedBuild" />
</Sequence.Variables>

那么，我的第一个问题...是否可以在序列变量中运行没有返回值的代码行？

我对这些技术还很陌生，所以可能错过了一些基本知识。如果有人有不同的方法将以前的版本号传递给下一个版本，我们也将不胜感激。

非常感谢你能走到这一步:-)

感谢@Jason Stangroome对于他的原始博客文章，并向我指出 InvokeMethod事件。在优秀的帮助下WCF & WF Samples for .NET 4 ，我像这样更新了 XAML:

<Sequence DisplayName="Queue chained build" sap:VirtualizedContainerService.HintSize="222,146">
    <Sequence.Variables>

        <Variable x:TypeArguments="x:String" Default="[ChainedBuildRequest.ProcessParameters]" Name="NextBuildProcessParameters" />
        <Variable x:TypeArguments="scg:IDictionary(x:String, x:Object)" Default="[WorkflowHelpers.DeserializeProcessParameters(NextBuildProcessParameters)]" Name="DeserializedParameters" />
