避免需要将NuGet.exe添加到源代码管理 [英] Prevent needing to add NuGet.exe to source control

问题描述

某些环境:
我已经按照关于在不提交软件包的情况下使用NuGet的教程取得了一些成功.解决了此NuGet问题之后，通过为nuget手动添加<RestorePackages>和<Import ...>来解决此问题.目标文件运行正常.

Some context:
I've followed the tutorial on using NuGet without committing packages with some success. After working around this NuGet issue by manually adding <RestorePackages> and a <Import ...> for the nuget.targets file things were working.

但是，一旦我用Mercurial克隆了存储库，构建时就会出现以下错误:

However, once I cloned the repository with Mercurial, I got the following error when building:

无法找到'C:\ ... \ Visual Studio 2010 \ Projects \ MyProject \ .nuget \ nuget.exe'

Unable to locate 'C:\...\Visual Studio 2010\Projects\MyProject\.nuget\nuget.exe'

这很有意义，因为我的忽略模式使我无法检入exe文件.从这个相关的SO问题，我推断出将此文件包含在版本控制中并不少见(或者是?)，但是如果可以，我真的宁愿不要将NuGet.exe提交到版本控制中.

This makes sense, because my ignore pattern prevented me from checking in the exe file. From this related SO question I inferred that it's not uncommon to have this file in version control (or is it?), but really I'd prefer not to commit NuGet.exe to version control if I can help it.

问题:是否有一种方便的方法来防止需要检入NuGet.exe?

Question: Is there a convenient way to prevent needing to check in NuGet.exe?

我尝试了一些Google-fu，整理了一下文档，并摆弄了NuGet.targets文件，但到目前为止还算不上成功.如果我可以动态地指向构建解决方案的特定环境的NuGet.exe，那似乎是可取的.

I've tried some Google-fu, skimming the documentation, and fiddling with the NuGet.targets file, no luck so far. It seems preferable if I could just dynamically point to the NuGet.exe of the particular environment that's building the solution.

我知道我可以只添加exe文件，但是我更想知道是否还有其他方法可以解决这个问题，或者知道为什么没有可行的替代方法.

I know I could just add the exe file, but I'd prefer to know if there are other ways to handle this or know why there are no viable alternatives.

更新:
nuget.targets文件包含一些相关的xml:

Update:
The nuget.targets file holds some relevant xml:

<!-- only (relevant) parts of the xml shown below -->
<DownloadNuGetExe Condition=" '$(DownloadNuGetExe)' == '' ">false</DownloadNuGetExe>
...
<UsingTask TaskName="DownloadNuGet" TaskFactory="CodeTaskFactory" AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v4.0.dll">
    <Task>
        <Code Type="Fragment" Language="cs">
        <![CDATA[
        try {
            OutputFilename = Path.GetFullPath(OutputFilename);

            Log.LogMessage("Downloading latest version of NuGet.exe...");
            WebClient webClient = new WebClient();
            webClient.DownloadFile("https://nuget.org/nuget.exe", OutputFilename);

            return true;
        }
        catch (Exception ex) {
            Log.LogErrorFromException(ex);
            return false;
        }
        ]]>
        </Code>
    </task>
</UsingTask>

我不熟悉.targets文件的工作原理，但这似乎与我要寻找的一致.戴着牛仔帽，我尝试将DownloadNuGetExe元素中的false更改为true，但这没有按预期方式工作(带有或不带有condition属性).

I'm unfamiliar with the workings of .targets files, but this seems to be along the lines of what I'm looking for. With my cowboy-coding hat on I tried changing the false to true in the DownloadNuGetExe element, but this didn't work as expected (with or without the condition attribute).

推荐答案

只需检查一下:nuget.targets是一个msbuild文件.而且您走对路了，

Just checked: nuget.targets is an msbuild file. And you were on the right way, in:

<DownloadNuGetExe Condition=" '$(DownloadNuGetExe)' == '' ">false</DownloadNuGetExe>

将值更改为true:

<DownloadNuGetExe Condition=" '$(DownloadNuGetExe)' == '' ">true</DownloadNuGetExe>

但是您必须重新启动Visual Studio或重新加载解决方案(请参阅注释)，才能生效.

But you must restart Visual Studio or reload the solution (see comments) after this to take effect.
