“GenerateJavaStubs”任务失败

Question

这个问题目前正在撞墙，这个错误阻止我构建和运行我的应用程序。这是一个PCL项目。

   Error The "GenerateJavaStubs" 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.

我在PCL中的汇编信息：

using System.Resources;
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

[assembly: AssemblyTitle("ConstructionMobileApp")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]

[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]
[assembly: NeutralResourcesLanguage("en")]

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

Android程序集信息：

Answer 1

您正在尝试编译的项目的路径是什么？

Windows对路径名称有限制，因此请尝试将项目移动到较短的命名路径。 例如，如果您使用C:\Users\YourUserName\Documents\VisualStudio2015\Projects\something的默认项目路径，则可以将其复制到C:\Dev。

Answer 2

只是复制here的答案：

尝试在项目中添加此msbuild属性，以缩短obj目录中的文件/文件夹名称

<PropertyGroup>
    <UseShortFileNames>True</UseShortFileNames>
</PropertyGroup>

或者这将输出文件夹更改为更接近C:\的文件夹

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
    <IntermediateOutputPath>C:\MyFolder\MyProj</IntermediateOutputPath>
</PropertyGroup>

希望能帮助到你。
