在运行时获取 $(SolutionDir)

Question

我已经设法使用此任务在运行时获取 $(SolutionDir) 变量：

<Target Name="GenerateCode" Outputs="$(IntermediateOutputPath)ResourcesPath-Constants.cs">
  <Exec Command=
        "
        echo namespace SRE.Widgets.Blend &gt; $(IntermediateOutputPath)ResourcesPath-Constants.cs
        echo { &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.cs
        echo     public static partial class ResourcesPath &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.cs
        echo     { &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.cs
        echo         public static string SOLUTION_DIR = @&quot;$(SolutionDir)&quot;; &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.cs
        echo     } &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.cs
        echo } &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.cs
        " />
</Target>
<Target Name="CompileGeneratedCode">
  <ItemGroup>
    <Compile Include="$(IntermediateOutputPath)ResourcesPath-Constants.cs" />
  </ItemGroup>
</Target>
<PropertyGroup>
  <CompileDependsOn>
    GenerateCode;
    CompileGeneratedCode;
    $(CompileDependsOn);
  </CompileDependsOn>
</PropertyGroup>

我遇到的问题是，由于该任务没有“输入”，因此始终会构建该项目。这很奇怪，因为它破坏了增量编译。该项目用于不同的解决方案，我只希望在更改解决方案时对其进行编译。

我尝试使用 Inputs="$(SolutionPath)。如果您只使用一种解决方案，那么这种方法效果很好，但是当您使用另一种解决方案中的项目时，sln.cache 会损坏并永远停止构建任务。无论您是否删除“输入”变量。让它再次工作的唯一方法是删除 .sln.cache 文件。

方法可以停止项目的每次编译吗？

什么

有谁知道有 解决办法：

<Target Name="GenerateTmpCode">
  <Exec
    Command=
        "
        echo namespace SRE.Widgets.Blend &gt; $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp
        echo { &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp
        echo     public static partial class ResourcesPath &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp
        echo     { &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp
        echo         public static string SOLUTION_DIR = @&quot;$(SolutionDir)&quot;; &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp
        echo     } &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp
        echo } &gt;&gt; $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp
        fc $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp $(IntermediateOutputPath)ResourcesPath-Constants.g.cs
        "
    ContinueOnError="true">
    <Output PropertyName="CommandExitCode" TaskParameter="ExitCode"/>
  </Exec>
</Target>

<Target Name="GenerateCode"
        Condition="'$(CommandExitCode)'!='0'"
        Outputs="$(IntermediateOutputPath)ResourcesPath-Constants.cs"
        Inputs="$(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp" >
  <Exec Command=
        "
        copy $(IntermediateOutputPath)ResourcesPath-Constants.g.cs.tmp $(IntermediateOutputPath)ResourcesPath-Constants.g.cs
        " />
</Target>

<Target Name="CompileGeneratedCode">
  <ItemGroup>
    <Compile Include="$(IntermediateOutputPath)ResourcesPath-Constants.g.cs">
      <AutoGen>True</AutoGen>
    </Compile>
  </ItemGroup>
</Target>

<PropertyGroup>
  <CompileDependsOn>
    GenerateTmpCode;
    GenerateCode;
    CompileGeneratedCode;
    $(CompileDependsOn);
  </CompileDependsOn>
</PropertyGroup>

有两个第一个在临时文件中创建一个包含 $(solutiondir) 值的字符串的部分类，并将其与当前使用的部分类进行比较（如果需要），第二个将复制临时文件。
