xbuild：在项目中找不到目标。 c# 类库答案

【问题标题】：xbuild: No target found in the project. c# class libxbuild：在项目中找不到目标。 c# 类库
【发布时间】：2016-03-31 13:52:12
【问题描述】：

我正在尝试在 Ubuntu 14.4 LTS 上使用 xbuild 编译项目。我有单声道 4.2.3 和 xbuild 12

整个解决方案之前是在 OSX 上使用 mono 构建的，但我的大学已经进行了一些更改（例如重命名项目），现在它也无法在 OSX 上构建。我一生都无法弄清楚导致这种情况发生的变化。它继续在 Visual Studio 中构建良好，并在 Jenkins 上使用 msbuild。

解决方案中有5个项目，最初都返回错误

<Projfile>:error : No target found in the project

经过一番谷歌搜索后，我将以下内容添加到我的所有项目文件中。

<Target Name="Build" DependsOnTargets="$(BuildDependsOn)" Outputs="$(TargetPath)" />

现在，只有 2 个类库项目返回此错误。

我已经通过运行诊断日志检查了我所有的 msbuild 变量是否设置为正确的路径，并且我还发现了一些 SO 帖子，这些帖子可以通过是否正确安装了 mono。

我有点不知所措。

编辑

这是按要求使用 /v:diag 运行的输出。

真正奇怪的是，我的 csproj 文件一开始看起来就像它们在源代码管理中的样子。类似这样的东西（因字数限制而删节）

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="12.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />
  <PropertyGroup>
    <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
    <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform>
    <ProjectGuid>{DAA924E0-7C89-4E49-B1C6-28B66ABAC229}</ProjectGuid>
    <OutputType>Library</OutputType>
    <AppDesignerFolder>Properties</AppDesignerFolder>
    <RootNamespace>Microlise.MonoTemplate.Logger</RootNamespace>
    <AssemblyName>Microlise.MonoTemplate.Logger</AssemblyName>
    <TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
    <FileAlignment>512</FileAlignment>
    <SolutionDir Condition="$(SolutionDir) == '' Or $(SolutionDir) == '*Undefined*'">..\</SolutionDir>
    <RestorePackages>true</RestorePackages>
    <TargetFrameworkProfile />
  </PropertyGroup>
......

但是如果我在构建失败后查看它，它已变为：

<?xml version="1.0" encoding="utf-8">                                                       
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" />

这就是文件中的全部内容。没有目标，什么都没有。所以在我看来，好像 xbuild/mono 在出于某种原因执行构建时正在修改 csproj 文件？

这是来自 Logger 项目的导入\

<Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />

【问题讨论】：

那个限制是没用的。您必须通过开关启用诊断日志记录才能生成更多日志条目。
是的，正如我所说，我已启用诊断日志记录，但它并没有给我任何新内容。它真正为我做的只是确认变量设置正确
你有旧的 .csproj 文件吗？如果是，则比较两者并查看差异。
您能分享一下使用 /v:diag 运行 xbuild 的完整输出吗？
@radical 我已将构建输出添加到问题中。

【解决方案1】：

好的，所以这都是 NuGet.exe 过时的症状。我不确定我使用的版本来自哪里，但我用来恢复软件包的命令是：

nuget update -safe Microlise.MonoTemplate.sln -repositoryPath ./packages

更新 nuget 后，我现在可以简单地运行

nuget restore Microlise.MonoTemplate.sln

其他问题都消失了。
