Question

我的解决方案由一个主要的Web应用程序组成，并附加了一些Azure Web作业。当我去发布主要的Web应用程序时，我收到此错误：

[project_path]\[project_name].csproj(0,0): Error MSB4057: The target "AddScheduledJob" does not exist in the project.

我不确定AddScheduledJob的来源。它不是解决方案中任何项目的名称。

我想我已经找到了“尝试”文件来引用这个幻影项目：

[solution_path]\packages\Microsoft.Web.WebJobs.Publish.1.0.7\tools\webjobs.console.targets

此文件包含以下文本片段：

 <Target Name="AddScheduledJob"
      DependsOnTargets="$(AddScheduledJobDependsOn)"
      AfterTargets="MSDeployPublish"
      Condition="'$(FilePreview)' == 'false' and ('$(WebJobPublishFromWAP)' == 'true' or '$(_DestinationType)' == 'AzureWebSite')">

<CreateScheduledWebJob JobConfig="@(JobConfig)"  
                       WebSiteName="$(WebSiteName)" 
                       WebSiteUrl="$(WebSiteUrl)"
                       ManagementUri="$(WebJobManagementUri)"
                       ManagementCertificatePath="$(ManagementCertificatePath)"
                       ManagementCertificatePassword="$(ManagementCertificatePassword)"
                       ManagementCertificate="$(ManagementCertificate)"
                       ManagementToken="$(ManagementToken)"
                       PublishSettingsPath="$(PublishSettingsPath)"
                       SubscriptionId="$(SubscriptionId)"
                       Condition="'%(RunMode)' == 'Scheduled'"/>

我不知道这是哪里来的，或者为什么会引起问题。我很想只删除该代码段，但是在文件顶部，我阅读了该代码段：

WARNING:  DO NOT MODIFY this file, this file is added to your project automatically...

我可以安全地从“ webjobs.console.targets”文件中删除此代码段吗？还是还有其他可能发生的事情？

更新

我发现，即使出现此错误，我的Web应用程序也已成功发布。这是发布过程结束时日志的更深入视图：

如您所见，它说“发布成功”，然后抱怨其中一个作业的“ StartTime”。然后抱怨“ AddScheduledJob”。我不关心“ StartTime”问题。我可以解决的。但是有关名为“ AddScheduledJob”的项目的错误令人困惑。即使发布似乎发生了，我也不希望这个错误使日志混乱。是什么导致此错误？

Answer 1

那是一个古老的NuGet软件包。在较早的版本中，如果您将Webjob配置为按计划而不是连续运行，则Visual Studio允许您配置该计划的计划。您可以按照以下指南删除该目标并配置计划：https://docs.microsoft.com/en-us/azure/app-service/web-sites-create-web-jobs#CreateScheduledCRON。如果您使用的是旧版的Visual Studio，请进行升级，以便拥有最新的WebJob项目模板。

Answer 2

首先，您必须从Nuget添加Microsoft.Web.WebJobs.Publish软件包。即使VS具有“发布到网络作业”操作，它也不会自动将该软件包添加到您的项目中。您可以参考此blog。

添加后，您仍然会感到困惑。 VS不会自动修改您的.csproj文件以使用此软件包。为此，您需要手动修改.csproj文件。最简单的方法是将其卸载到VS中，然后在CSharp目标之后添加以下行–我在上下文中包括了该行：

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<Import Project="..\packages\Microsoft.Web.WebJobs.Publish.1.0.11\tools\webjobs.targets" 
Condition="Exists('..\packages\Microsoft.Web.WebJobs.Publish.1.0.11\tools\webjobs.targets')" />

与您类似的issue。当他在asp.net网站上添加新的WebJob时，请保留Microsoft.Web.WebJobs.Publish软件包的较新版本。

从Visual Studio发布到Azure时，“项目中不存在目标'AddScheduledJob'”
