Xamarin Android 文件路径变长

Question

当我尝试构建我的 Xamarin 项目时，我总是收到以下错误。

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，我用谷歌搜索了这个错误，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 文件夹设置在 C:\TEMP。但是，这些似乎都没有帮助。当我查看给出此错误的代码行时，Visual Studio 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>

具体错误指向第四行。我不能修改这个文件，所以我没有在这里尝试任何东西。

我真的不知道该尝试什么了，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，这也不起作用。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，只能提供解决方法。

当我们将 Xamarin 升级到最新版本时开始发生这种情况，所以我想作为最后的手段，您可以降级回以前的版本。

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要长得多，因此我创建了一个普通用户帐户并以该用户身份运行 CC.NET 服务。这解决了问题。

Answer 3

遇到了同样的问题，还不能解决，但是好像没有创建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，因为目录有 130 个字符长，文件有 142 个字符。

目前解决这个问题的唯一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）
