Question

为什么它不能用于<Import />这个文件，当它替换语句时只需复制粘贴三个属性就可以了？

../../ Setup.Version.proj

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <InstallerMajorVersion>7</InstallerMajorVersion>
        <InstallerMinorVersion>7</InstallerMinorVersion>
        <InstallerBuildNumber>7</InstallerBuildNumber>
    </PropertyGroup>
</Project>

使用：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <InstallerMajorVersion>7</InstallerMajorVersion>
        <InstallerMinorVersion>7</InstallerMinorVersion>
        <InstallerBuildNumber>7</InstallerBuildNumber>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>

不起作用：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="../../Setup.Version.proj" />
    <PropertyGroup>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>

这里的变量只是简单地用空字符串...... :(我确定导入项目的路径是正确的。

所以当我从命令行运行msbuild时似乎工作正常，但是当我在Visual Studio中构建项目时却没有。为什么在这个世界？

我试图重现并且一切正常：

<强> importme.proj

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <InstallerMajorVersion>7</InstallerMajorVersion>
        <InstallerMinorVersion>7</InstallerMinorVersion>
        <InstallerBuildNumber>7</InstallerBuildNumber>
    </PropertyGroup>
</Project>

<强> main.proj

<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="importme.proj" />
    <PropertyGroup>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>
    </PropertyGroup>
    <Target Name="Build">
        <Message Text="$(OutputName)"/>
    </Target>
</Project>

<强>输出

使用

运行

msbuild main.proj

更新：您需要为要更新的Include'd文件重新加载项目，或使用workaround。

Answer 2

它没有工作的原因是Visual Studio缓存了包含的文件，因此我对其所做的任何更改都没有生效，直到我重新加载解决方案或重新启动Visual Studio。这似乎是VS 2010的限制。重新加载VS 2010后，一切都按预期工作。

Answer 3

Import元素仅在Project元素下有效。但是，代码似乎想要将值导入<ProjectGroup>元素。尝试将值声明为Setup.Version.proj中的变量，并在主MSBuild文件中引用它们，例如：

<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="../../Setup.Version.proj" /> <!-- Variables declared in here -->
    <PropertyGroup>
        <InstallerMajorVersion>$(MyInstallerMajorVersion)</InstallerMajorVersion>
        <InstallerMinorVersion>$(MyInstallerMinorVersion)</InstallerMinorVersion>
        <InstallerBuildNumber>$(MyInstallerBuildNumber)</InstallerBuildNumber>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>

VS2010 - 使用<import>在安装项目之间共享属性？</import>

所以当我从命令行运行msbuild时似乎工作正常，但是当我在Visual Studio中构建项目时却没有。为什么在这个世界？
