Question

当我尝试构建我的Xamarin项目时，我总是会收到以下错误。

指定的路径，文件名或两者都太长。完全限定的文件名必须少于260个字符，目录名必须少于248个字符。

当然我用Google搜索了这个错误并发现它很常见，所以我尝试了很多不同的解决方案。我将所有项目文件和我的Android SDK，NDK等直接移动到C：。我还将我的TEMP文件夹设置为C：\ TEMP。但是，这似乎没有帮助。当我查看出现此错误的代码行时，Visual Studio会将我发送到Xamarin.Android.Common.targets中的这行代码。

<Target Name="_BuildAdditionalResourcesCache"
  Inputs="@(ReferencePath);@(ReferenceDependencyPaths)"
  Outputs="$(_AndroidResourcePathsCache)"
 >
 <GetAdditionalResourcesFromAssemblies
  AndroidSdkDirectory="$(_AndroidSdkDirectory)"
  AndroidNdkDirectory="$(_AndroidNdkDirectory)"
  Assemblies="@(ReferencePath);@(ReferenceDependencyPaths)"
  CacheFile="$(_AndroidResourcePathsCache)"
  Condition=" '$(DesignTimeBuild)' != 'true' "
 />
</Target>

错误指向第四行是具体的。我无法修改此文件，因此我没有尝试任何操作。

我真的不知道该怎么办，所以非常欢迎任何解决方案！我已经尝试卸载并重新安装Visual Studio和Xamarin，但这也无法正常工作。该项目在其他计算机上运行良好。

Answer 1

编辑您的Android项目文件并添加IntermediateOutputPath属性以将该项目的输出重定向到更短的路径（可以是绝对路径或相对路径）。

<IntermediateOutputPath>..\..\shorter-path</IntermediateOutputPath>

Answer 2

我们遇到了同样的问题。我无法提供解决方案，只能解决方法。

当我们将Xamarin升级到最新版本时，它开始发生，所以我想作为最后的手段，你可以降级回到以前的版本。

富

更新：我们在LocalSystem帐户下运行CC.NET服务（调用MSBuild）。这意味着AppData路径比常规用户长得多，因此我创建了一个常规用户帐户并以此用户身份运行CC.NET服务。这解决了这个问题。

Answer 3

遇到同样的问题，暂时无法解决，但看起来没有创建resourcepaths.cache文件，因为systemprofile appdata的路径太长了。

C:\Windows\system32\config\systemprofile\AppData\Local\Xamarin\
C:\Windows\system32\config\systemprofile\AppData\Local\Xamarin\Xamarin.Android.Support.Animated.Vector.Drawable\23.4.0.0\embedded
C:\Windows\system32\config\systemprofile\AppData\Local\Xamarin\Xamarin.Android.Support.Animated.Vector.Drawable\23.4.0.0\embedded\classes.jar

仍然很奇怪，因为目录长130个字符，文件142。

目前只有解决问题的方法是以本地管理员身份运行构建。

Answer 4

我通过以管理员身份运行Visual Studio并取消选中来解决它：

使用共享运行时
启用开发人员检测（调试和分析）

在Droid项目属性中，在 Android选项标签上。

Xamarin Android文件路径很长
