但现在它失败了：

它有相同的错误信息，但现在还有“Dotnet命令失败，以下项目的退出代码不为零...”

Answer 1

我可以确认，我们已经看到了完全相同的行为，而我们没有对构建管道或源代码进行任何更改。第一个失败的构建在任务日志顶部的横幅中也有Version : 2.173.0。

在我们的例子中，错误是由于多个依赖的nuget包导致的，这些包都包含一个.targets文件，其中的元素如下：

<Content Include="Deployment\**\*.*" Pack="true" PackagePath="\..\Deployment\" />

错误一直由任务记录，只有以前的版本忽略了它，并且仍然通过了构建。这是因为尽管出现错误，nuget pack仍会发出.nupkg文件。

我们的解决方法是在include之前添加一个Remove元素：

<Content Remove="Deployment\**\*.*" />
<Content Include="Deployment\**\*.*" Pack="true" PackagePath="\..\Deployment\" />

Answer 2

您提供的日志显示该错误是由于您的.NET Core SDK/运行时版本太旧而导致的。

推荐的解决方案是在原始任务之前添加UseDotNet任务：

- task: UseDotNet@2
  inputs:
    version: {version}

您还可以将自托管代理与您想要的.NET Core SDK/运行时版本一起使用，而不是托管代理，或者使用较新的版本。但这两种解决方案都会显著改变建筑环境，因此需要根据您的情况谨慎使用。

Answer 3

dotnet包最近出现故障

根据错误消息：

错误NU5118:未添加文件'Create-Identity.sql‘，因为包已包含文件'content\Create-Identity.sql’

似乎项目中有IncludeSource=true，而中有几个文件具有相同的文件名。这就是为什么它说包已经包含文件的原因。

要解决此问题，最简单的方法是删除相同的文件或重命名(如果可能)。

如果我们无法删除或重命名这些文件，我们可以尝试使用不同目标路径中的这些文件来创建nuspec文件。
