尝试找到您的项目不具有在其非ASCII字符的路径;您的用户名是统一code和构建系统无法处理具有非ASCII统一code路径名。

这其实是Java中的一个缺陷，是相当困难的修复;看https://$c$c.google.com/p/android/issues/detail?id=56102了解详细信息。它的关键是，Java的发射器使用了错误的Windows API调用来从操作系统的命令行。

Try locating your projects in a path that doesn't have non-ASCII characters in it; your username is in Unicode, and the build system can't handle pathnames that have non-ASCII Unicode.

This is actually a bug in Java and is quite difficult to fix; see https://code.google.com/p/android/issues/detail?id=56102 for details. The crux of it is that Java's launcher uses the wrong Windows API call to fetch its command line from the OS.
