在 Window 10 上构建 Android 项目时出错 [英] Error when building Android Project on Window 10

问题描述

在为 Android 构建时，我一直遇到此错误:

When building for Android I keep having this error:

是什么原因造成的?我如何解决它?似乎不会发生在 CI 构建中.

What is causing it? How do I fix it? Doesn't seem to happen on the CI builds.

推荐答案

这里有一些方法可以用来解决 MAX_PATH 长度问题:

Here's a few methods you can use to fix MAX_PATH length issues:

在 Xamarin.Android .csproj 中:

1. True - 强制构建过程使用较短的路径名.

1. <UseShortFileNames>True</UseShortFileNames> - Forces the build process to use shorter path names.

<IntermediateOutputPath>C:\Projects\MyApp</IntermediateOutputPath> - 指定一个公共的中间输出根以制作更短的路径.

<IntermediateOutputPath>C:\Projects\MyApp</IntermediateOutputPath> - Specifies a common intermediate output root to make a shorter path.

更改组策略:

1. 启用 Win32 长路径支持(在 Visual Studio 2019+ 中受支持):https://blogs.msdn.microsoft.com/jeremykuhne/2016/07/30/net-4-6-2-and-long-paths-on-windows-10/
