asp.net-core - 从 Visual Studio 2015 发布 asp.net 5 时出现“路径太长”

Question

这似乎是一个常见问题，我发现了几个 Stack Overflow 问题，但它们似乎都与 MSBuild 有关。

我试图通过在 Visual Studio 中右键单击我的 asp.net 5 rc1 项目并调用基于文件系统的发布配置文件来发布。

它的设置如下所示：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <WebPublishMethod>FileSystem</WebPublishMethod>
        <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
        <LastUsedPlatform>Any CPU</LastUsedPlatform>
        <SiteUrlToLaunchAfterPublish />
        <LaunchSiteAfterPublish>True</LaunchSiteAfterPublish>
        <ExcludeApp_Data>False</ExcludeApp_Data>
        <CompileSource>False</CompileSource>
        <_DefaultDNXVersion>dnx-clr-win-x86.1.0.0-rc1-final</_DefaultDNXVersion>
        <UsePowerShell>True</UsePowerShell>
        <IISCommand>web</IISCommand>
        <WebRoot>wwwroot</WebRoot>
        <WwwRootOut>wwwroot</WwwRootOut>
        <IncludeSymbols>False</IncludeSymbols>
        <Native>False</Native>
        <IgnoreDNXRuntime>False</IgnoreDNXRuntime>
        <publishUrl>C:\Source\CCollections\artifacts\bin\CCollections.Client.Web.Angular\Release\PublishOutput</publishUrl>
        <DeleteExistingFiles>False</DeleteExistingFiles>
    </PropertyGroup>
</Project>

这会产生以下输出：

C:\Source\CCollections\src\CCollections.Client.Web.Angular>

我想我的问题在这里：C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\

我需要使用较短的路径，例如 C:\Temp。

我已经尝试了其他堆栈溢出答案中的一些建议。

添加<AspnetCompileMergeIntermediateOutputPath>c:\shortPath\</AspnetCompileMergeIntermediateOutputPath>到个人资料似乎没有帮助。

添加<IntermediateOutputPath>..\Temp</IntermediateOutputPath>似乎也不起作用。

我猜这是因为这些设置被 MSBuild 拾取，而不是 dnu 发布。

那么如何告诉 dnu publish 在 C:\Temp 而不是我的 appdata 目录中构建包？

更新：找到罪魁祸首：我认为超出路径限制的文件不在上面的日志中，并且只记录了成功的副本。为了检验这个假设：

我通过手动运行 dnu publish 部署到 c:\temp
将文件从 c:\temp 复制到 C:\Users\Christopher\AppData\Local\Temp\PublishTemp
运行脚本以递归方式迭代所有文件并输出超过 248 个字符的路径长度。结果：

C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\approot\packages\Microsoft.Extensions.Configuration.FileProviderExtensions\1.0.0-rc1-final\lib\net451\Microsoft.Extensions .Configuration.FileProviderExtensions.dll

文件路径长：249 个字符

C:\Users\Christopher\AppData\Local\Temp\PublishTemp\CCollections.Client.Web.Angular96\approot\packages\Microsoft.Extensions.Configuration.FileProviderExtensions\1.0.0-rc1-final\lib\netcore50\Microsoft.Extensions .Configuration.FileProviderExtensions.dll

文件路径长：252 个字符

最大的文件夹是 191 个字符，文件是 252 个字符，因此分别不超过 240 和 260 个字符。

不管这一切，我如何告诉 Visual Studio 2015 使用“C:\temp”作为它的临时目录，而不是我的配置文件的临时目录？

将临时输出更改为具有较短路径名的路径。

从文本编辑器.pubxml中打开您的目标。.\Properties\PublishProfiles
更改或添加名为 PublishOutputPathNoTrailingSlashunder的元素PropertyGroup并将值设置为所需的路径。

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <PublishOutputPathNoTrailingSlash>C:\Temp\Publish</PublishOutputPathNoTrailingSlash>
  </PropertyGroup>

对于 project.json 中的新 asp.net mvc 6 使用

"exclude": [ "wwwroot", "node_modules" ],`
"publishExclude": [ "**.user",  "**.vspscc" ]

score 0 · Accepted Answer

我想这就是你要找的：

当您进入“发布 Web”对话框时，您需要在“连接”选项卡中更改“目标位置”。（点击方形框...）然后浏览到 C:\Temp 和您的文件去那里...

该对话框不允许您即时创建 C:\Temp，因此如果您尚未创建它，则需要事先创建。

我确实希望这样做。
