use*_*725 6 c# android visual-studio xamarin.android xamarin
When I try to build my Xamarin project I always get the following error.
The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.
Of course I Googled this error and found out that it is quite common, so I tried a lot of different solutions. I moved all my project files and my Android SDK, NDK's etc directly to C:. I also set my TEMP folder at C:\TEMP. However, non of this seems to help. When I look at the line of code that gives this error, Visual Studio sends me to this line of code in Xamarin.Android.Common.targets.
<Target Name="_BuildAdditionalResourcesCache"
Inputs="@(ReferencePath);@(ReferenceDependencyPaths)"
Outputs="$(_AndroidResourcePathsCache)"
>
<GetAdditionalResourcesFromAssemblies
AndroidSdkDirectory="$(_AndroidSdkDirectory)"
AndroidNdkDirectory="$(_AndroidNdkDirectory)"
Assemblies="@(ReferencePath);@(ReferenceDependencyPaths)"
CacheFile="$(_AndroidResourcePathsCache)"
Condition=" '$(DesignTimeBuild)' != 'true' "
/>
</Target>
The error points to the fourth line to be specific. I can't modify this file so I didn't try anything here.
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.

我们有同样的问题。我无法提供解决方案，只能提供解决方法。
当我们将 Xamarin 升级到最新版本时，这种情况就开始发生，所以我想作为最后的手段，您可以降级回以前的版本。
富有的
更新：我们在 LocalSystem 帐户下运行 CC.NET 服务（调用 MSBuild）。这意味着 AppData 路径比普通用户的路径长得多，因此我创建了一个普通用户帐户并以此用户身份运行 CC.NET 服务。这解决了问题。
