Question

在MVC4中，如果我为解决方案中的所有项目创建新的构建配置，那么在构建Web .csproj时我会得到以下内容：

msbuild Company.Directory.Web.csproj /p:Configuration=Dev

[错误] C：\ WINDOWS \ Microsoft.NET \框架\ v4.0.30319 \ Microsoft.Common.targets（483， 9）：没有为项目设置OutputPath属性 'Company.Directory.Web.csproj'。请检查以确保您已指定Configuration和Platform的有效组合这个项目。 Configuration ='Dev'Platform ='AnyCPU'。你可能看到这条消息，因为你正试图建立一个没有的项目解决方案文件，并指定了非默认配置或该项目不存在的平台。

但是，设置了OutputPath属性！

这是一个错误吗？我该如何解决？

Answer 1

事实证明，第一个PropertyGroup很重要。由于某种原因，Visual Studio在其前面插入了新配置（Dev）PropertyGroup。我猜它是一个错误。我通过将新配置移到其他配置后来修复它。

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

  <PropertyGroup>
    <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>

Answer 2

尝试使用msbuild.exe从命令行构建时出现类似错误。我的问题是当我应该放'AnyCPU'时，我指的是'任何CPU'。

Answer 3

我与Azure项目有类似的问题。在我将新配置Release-CLOUD-STAGE添加到解决方案后，我开始收到相同的错误：

未为项目
设置OutputPath属性

在编辑器中打开ccproj文件并搜索新配置后，我看到它接近结尾：

  <PropertyGroup Condition=" '$(Configuration)' == 'Release-CLOUD' ">
    <OutputPath>bin\Release-CLOUD\</OutputPath>
  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)' == 'Release-CLOUD-STAGE' ">
    <OutputPath>bin\Release-CLOUD-STAGE\</OutputPath>
  </PropertyGroup>

一切对我来说都很好 - 现有配置Release-CLOUD效果很好，但新配置没有。事实证明，项目文件中有两个PropertyGroup元素 - 一个 - 完成 - 在项目文件的最开头：

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release-CLOUD|AnyCPU' ">
    <DebugType>pdbonly</DebugType>
    <Optimize>true</Optimize>
    <OutputPath>bin\Release-CLOUD\</OutputPath>
    <DefineConstants>TRACE</DefineConstants>
    <ErrorReport>prompt</ErrorReport>
    <WarningLevel>4</WarningLevel>
  </PropertyGroup>

然后由于某种原因还有另一个，上面显示的SHORT版本，插入到文件末尾附近。在为新PropertyGroup配置创建Release-CLOUD-STAGE元素的正确COMPLETE版本之后（并删除了两个SHORT版本） - 一切都已完成。

我不确定这是否特定于Azure，但我确实浪费了一些时间，所以我也希望分享我的发现。

Answer 4

我有两个没有条件的PropertyGroup元素，我认为后者阻止前者生效。我将所有子项合并到第一个PropertyGroup元素中并删除了第二个，然后事情开始工作。

Answer 5

我为Azure WebRole项目收到了同样的错误，并将<PropertyGroup>元素手动添加到.csproj文件中。但是，我不小心将它们置于几个<Import>语句之下。构建将因问题中的错误而失败。

正确的订单

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Dev|AnyCPU'">
   <DebugSymbols>true</DebugSymbols>
   <OutputPath>bin\</OutputPath>
   <DefineConstants>DEBUG;TRACE</DefineConstants>
   <DebugType>full</DebugType>
   <PlatformTarget>AnyCPU</PlatformTarget>
   <ErrorReport>prompt</ErrorReport>
   <CodeAnalysisRuleSet>MinimumRecommendedRules.ruleset</CodeAnalysisRuleSet>
</PropertyGroup>
<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />

订单错误

<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Dev|AnyCPU'">

   <PlatformTarget>AnyCPU</PlatformTarget>
   <ErrorReport>prompt</ErrorReport
<CodeAnalysisRuleSet>MinimumRecommendedRules.ruleset</CodeAnalysisRuleSet>
</PropertyGroup>

设置OutputPath时，“没有为项目设置OutputPath属性”
