Nuget真是霸道啊。。。
我有这么个需求：
项目里想使用Common.Logging来输出log，但并不想固定的依赖log4net或者NLog之类的，所以我不能直接install log4net之类的package。但是运行时当然又需要，所以我要写个build脚本，整体build完了之后把log4net.dll之类的copy到debug下面。
于是问题就来了：我的所有project都没有依赖log4net，所以packages目录下自然就没有log4net.1.2.10咯，那我copy的时候source是啥？
首先想到的自然是Nuget从1.6开始提供的package restore功能，反正我已经自己写脚本了，调用一下NuGet.targets不就好了？
事实证明我图样图森破了。。。 打开NuGet.targets
<PackagesConfig>$([System.IO.Path]::Combine($(ProjectDir), "packages.config"))</PackagesConfig>
为毛写死了不许自定义啊。。。没关系，咱改了它
<PackagesConfig Condition="$(PackagesConfig) == ''">$([System.IO.Path]::Combine($(ProjectDir), "packages.config"))</PackagesConfig>
之后在我的脚本里添加如下内容
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Buid" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<RestorePackages>true</RestorePackages>
<PackagesConfig>$([System.IO.Path]::Combine($(MSBuildProjectDirectory), "MyComany.MyProduct.MySolution.Packages.config"))</PackagesConfig>
</PropertyGroup>
<Import Project="..\.nuget\nuget.targets" />
<!--Build All-->
<Target Name="Buid">
<CallTarget Targets="RestorePackages"/>
</Target>
</Project>
<Project ToolsVersion="4.0" DefaultTargets="Buid" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<RestorePackages>true</RestorePackages>
<PackagesConfig>$([System.IO.Path]::Combine($(MSBuildProjectDirectory), "MyComany.MyProduct.MySolution.Packages.config"))</PackagesConfig>
</PropertyGroup>
<Import Project="..\.nuget\nuget.targets" />
<!--Build All-->
<Target Name="Buid">
<CallTarget Targets="RestorePackages"/>
</Target>
</Project>
结果一运行，报错说我的"MyComany.MyProduct.MySolution.Packages.config"找不到。
我检查了好几遍路径都没错啊~~~结果把文件重命名为packages.config，成功了。。。
最后看了一下帮助(nuget help install)
usage: NuGet install packageId|pathToPackagesConfig [options]
Installs a package using the specified sources. If no sources are specified, all
sources defined in %AppData%\NuGet\NuGet.config are used. If NuGet.config spec
ifies no sources, uses the default NuGet feed.
Specify the id and optionally the version of the package to install. If a
path to a packages.config file is used instead of an id, all the packages
it contains are installed.

你妹啊！为啥只认packages.config啊！
