无法为Android构建“ Hello World” Xamarin应用

Question

我收到此错误：

Severity    Code    Description Project File    Line    Suppression State
Error       The "Javac" task failed unexpectedly.
System.IO.PathTooLongException: 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.

我的应用程序的名称为XamarinApp1；肯定不会太久？

这是开箱即用的默认Xamarin Android XAML项目。我只是试图建立它...

Answer 1

打开Android .csproj，然后插入此PropertyGroup，并用计算机中的短路径替换IntermediateOutputPath。MSBuild将在此处“ E：\ temp \ MyApp”创建输出文件。

<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <UseShortFileNames>True</UseShortFileNames>
    <IntermediateOutputPath>E:\temp\MyApp</IntermediateOutputPath>
  </PropertyGroup>
...
