MSBuild重置错误标志

我有一个任务在第一次调用时总会失败,因为它缺少一个文件,但我有一个 OnError 任务,它创建文件并恢复其他任务,但构建将始终失败,因为它处于错误状态。无论如何都要在 OnError Target?

中重置此错误状态

MSDN声明如下:

  

如果目标元素之一的任务失败且 ContinueOnError 属性设置为 ErrorAndStop OnError 元素>(或 false

话虽如此,如果我将 ContinueOnError 设置为 WarnAndContinue (或 true

,我将无法执行任务

这是我的代码:

<PropertyGroup>
    <AppVersion>0.0.0</AppVersion>
    <ChangelogFileName>Changelog_$(AppVersion).html</ChangelogFileName>
    <AppCastLocation>http://test/AppCast.xml</AppCastLocation>
</PropertyGroup> 

<!-- AppCastCreation target is the starting point, it attempts to download
     the AppCast.xml (Target=AppCastDownload), if it fails then we create
     a new AppCast.xml (Target=AppCastNew) and then update the AppCast with
     the new version bneing deployed (Target=AppCastUpdate) -->
<Target Name="AppCastCreation">
    <CallTarget Targets="AppCastDownload;AppCastUpdate" RunEachTargetSeparately="True" />
</Target>

<Target Name="AppCastDownload">
    <!-- Download latest AppCast.xml if it doesn't exist, then create a new one -->
    <WebDownload FileUri="$(AppCastLocation)" FileName="AppCast.xml" />
    <OnError ExecuteTargets="AppCastNew"/>
</Target>

<Target Name="AppCastNew">
    <!-- Create a new AppCast.xml -->
    <Message Text="Creating new AppCast.xml" />
    <Exec Command='python $(AppCastPublisherPath)AppCastPublisher.py new AppCast.xml "Changelog" "$(AppCastLocation)"'/>
    <OnError ExecuteTargets="MessageErrorHandler"/>
</Target>

<Target Name="AppCastUpdate" DependsOnTargets="AppCastDownload">
    <Message Text="Updating AppCast.xml with Version $(AppVersion)" />
    <!-- Create changeset info and upload -->
    <Exec Command="python GetJenkinsChangeset.py -html -out $(ChangelogFileName)" />
    <OnError ExecuteTargets="MessageErrorHandler"/>
</Target>

那么无论如何我可以重置我的 AppCastNew 目标中的错误状态,或者可能会执行另一个会执行相同结果的工作流程吗?

答案 0 :(得分:0)

您可以指定<OnError..."WarnAndContinue",然后使用条件检查$(MSBuildLastTaskResult)属性,而不是使用ContinueOnError

旧:

<WebDownload FileUri="$(AppCastLocation)" FileName="AppCast.xml" />
<OnError ExecuteTargets="AppCastNew"/>

新:

<WebDownload ContinueOnError="WarnAndContinue" FileUri="$(AppCastLocation)" FileName="AppCast.xml" />
<CallTarget Condition=" '$(MSBuildLastTaskResult)' == 'False' " Targets="AppCastNew"/>

(我相信"WarnAndContinue"$(MSBuildLastTaskResult)都是在MSBuild 4.0中引入的。)
