Error:(1, 0) Your project path contains non-ASCII characters. 这是个什么错误？

完整的是这样的：Error:(1, 0) Your project path contains non-ASCII characters. This will most likelycause the build to fail on Windows. Please move your project to a differentdirectory. See http://b.android.com/95744 for details.This warning can be disabled by using the command line flag-Dcom.android.build.gradle.overridePathCheck=true, or adding the line'com.android.build.gradle.overridePathCheck=true' to gradle.properties filein the project directory.从网上下demo直接用android studio import进去就报这个错，其他demo有时候可以，有时又不行，请问该怎么解决？
解决方法：
项目的路径上有中文，比如：E:/workspace/项目/Hello，把中文改一下就行了；
