包路径：org.apache.tools.ant.util.FileUtils
类名称：FileUtils
方法名：getRelativePath

FileUtils.getRelativePath介绍

[英]Calculates the relative path between two files.

Implementation note:
This function may throw an IOException if an I/O error occurs because its use of the canonical pathname may require filesystem queries.
[中]计算两个文件之间的相对路径。
实施说明：
如果发生I/O错误，此函数可能会引发IOException，因为它使用规范路径名可能需要文件系统查询。
